GROUP Aal1Ces CustomerIdentifierData (CidData)

Properties Provisioned

Description This group contains the attribute for a component’s CustomerIdentifier (CID). Refer to the attribute description for a detailedexplanation of CIDs.

ATTRIBUTE Aal1Ces customerIdentifier (cid)

Access Read and write

Description This attribute holds the Customer Identifier (CID).

Every component has a CID. If a component has acid attribute,the component’s CID is the provisioned value of that attribute;otherwise the component inherits the CID of its parent. The top-level component has a CID of 0.

Every operator session also has a CID, which is the CIDprovisioned for the operator’s user ID. An operator will see onlythe stream data for components having a matching CID. Also, theoperator will be allowed to issue commands for only thosecomponents which have a matching CID.

An operator CID of 0 is used to identify the Network Manager(referred to as “NetMan” in DPN). This CID matches the CID of

GROUP Aal1Ces Provisioned (Prov)


Description This group contains basic provisioning data for the AAL1 CircuitEmulation Service.

ATTRIBUTE Aal1Ces serviceType (servType)


Criticality Process

Description This attribute specifies the service type for the CES.

In anunstructured service, the entire data stream at the serviceinterface (including any framing bits which may be present) ispassed across the network transparently.

The unstructured service uses the Unstructured Data Transfer(UDT) mode of AAL1.

In a structured service, an Nx64kbit/s fraction of the data streamat the service interface is passed across the network. Two modesof structured service are supported:basicStructured andcasStructured. In acasStructured service, the ChannelAssociated Signalling (CAS) bits are carried in a separate datastructure from the Nx64 payload; in abasicStructured servicethey are not.

The structured service uses the Structured Data Transfer (SDT)mode as defined in ITU-T Recommendation I.363.1.

TheserviceType attributes at both ends of a connection must bethe same.

The4pDS3ChAal1 card does not supportcasStructured services.

ATTRIBUTE Aal1Ces bufferSize (bufSize)


Criticality Component

Description On4pDS1Aal1 and4pE1Aal1 cards, this attribute specifies thesize of the AAL1 receive segment reassembly buffer in bytes. Oninitialization the buffer is filled to a level determined bycellDelayVariationTolerance.Thereafter the buffer is emptied asTDM frames are transmitted, and is filled as ATM cells arereceived. If the buffer overflows, sufficient data is discarded tobring the level down to that set after initialization. The cause of abuffer overflow may be one or a combination of any of thefollowing: cell-arrival-jitter, initialization with delayed ATMcells, or TDM clock difference or wander.

On4pDS1Aal1 and4pE1Aal1 cards, if this attribute isautoConfigure, the buffer size applied is equivalent to two timescellDelayVariationTolerance. A provisioned numeric value ofbufferSize must be higher than the equivalentcellDelayVariationTolerance, plus an allowance of one ATMCell for the quantization of data in cells, and an allowance, ifapplicable, for the ATM overheads of structured CES.

On MSA and4pDS3ChAal1 cards this attribute’s value must beautoConfigure, to acknowledge thatmaximumBufferDelay isprovisioned instead of this attribute.

Setting this attribute too low allows traffic with normal CDV tocause unnecessary loss of data on the service interface. Settingthis attribute too high permits the buffer to introduce anunnecessarily high propagation delay.

Values Decimal (94..15651)autoConfigure



Units bytes

Default autoConfigure

ATTRIBUTE Aal1Ces cellLossIntegrationPeriod (lossPeriod)


Description This attribute specifies the cell loss integration period. Thisperiod defines the interval of time (in milliseconds) for which aloss of cells condition must persist before a buffer underflowalarm is raised. A loss of cells condition occurs when the flow ofcells to the AAL1 reassembly buffer stops, causing a bufferunderflow or starvation condition.

The operational attributecellLossStatus will be set tolosswhenthe buffer underflow alarm is raised, andnoLoss when it iscleared.

The minimum value of this attribute is 10 seconds for the4pDS3ChAal1 card.

The valueautoConfigure corresponds to a period of 10 secondson a4pDS3ChAal1 card, and 2 seconds on all other cards.

ATTRIBUTE Aal1Ces partialFill (partFill)



Description A significant source of delay in a structured service is the amountof time it takes to collect enough data to fill a cell. This period oftime can be reduced by sending cells that are only partially filledwith data (idlePattern octets are added to the ATM payloadbeyond the partial fill level).

This attribute specifies the number of payload octets to fill withdata. It is applicable to structured services only, and must be setto 47 for unstructured services.

On a given AAL1 Function Processor, the maximum cell rate thatcan be sustained is dependent upon the combined bandwidths ofthe provisioned services, and (for structured services) the levelsof partialFill . The smaller thepartialFill level, the greater thecell rate and hence the fewer the services that can be sustained atthat fill level.

On the4pDS3ChAal1 card, the only allowed value for thisattribute is47.

Values Decimal (8..47)

Units octets

Default 47

ATTRIBUTE Aal1Ces idleSuppression (idleSup)



Description This attribute controls the suppression of idle cells. An idle cell isone in which the bytes of the ATM payload (up to thepartialFilllevel) match theidlePattern.

If idleSuppression is off, idle cells are not suppressed.



If idleSuppression is on, at least 75% of cells are suppressedunder idle conditions.

The strategy is as follows: the first idle cell after a sequence ofnon-idle cells is always sent; those that follow are suppressed.Note, however, that at least one cell in eight is always sent (toallow the receive end to regenerate the suppressed cells) andmore often than not, two cells are sent (the cell containing theAAL1 pointer, which will almost always fail to match, and theone after that).

This feature is not supported by the4pDS3ChAal1 card. Thus,this attribute must be set tooff for this card type.

Values offon

Default off

ATTRIBUTE Aal1Ces idlePattern (idlePat)



Description This attribute specifies the pattern which the bytes of an ATMpayload, up to thepartialFill level, must match in order for thecell to be classified as idle. Payload bytes beyond thepartialFilllevel are not checked.

The suppression of idle cells is controlled by the attributeidleSuppression. If idleSuppression is on, at least 75% of cellsare suppressed under idle conditions.

Values Hex (H.0..H.ff)

Default H.7e

ATTRIBUTE Aal1Ces cellLossRecoveryPeriod (recPeriod)


Description This attribute specifies the cell loss recovery period. This perioddefines the interval of time (in seconds) for which a loss of cells


241-5701-060 2.0S1 Load 2.0.30

condition must desist before the buffer underflow alarm iscleared.

The operational attributecellLossStatus will be set tonoLosswhen the buffer underflow alarm is cleared.


Units seconds

Default 20

ATTRIBUTE Aal1Ces dummyDataByte



Description This attribute specifies the pattern which is played out onto theservice interface to maintain bit integrity when data is unavailablefrom the ATM network.

For an unstructured service (serviceType is set tounstructured),dummyDataByte must be set toFF.


Default H.ff

ATTRIBUTE Aal1Ces maximumBufferDelay (maxBufDelay)



Description This attribute specifies the maximum delay that a Cell DelayVariation buffer is permitted to add to the egress stream. Thedelay in the buffer is modified in response to variation in theegress cell stream. At the point that the delay would be modifiedin excess of the maximum, sufficient data is discarded that thedelay returns tocellDelayVariationTolerance.

Setting this attribute too low allows traffic with normal CDV tocause unnecessary loss of data on the service interface. Settingthis attribute too high permits the buffer to introduce an



unnecessarily high propagation delay.

If this attribute isautoConfigure, the maximum delay tolerated inthe buffer is two timescellDelayVariationTolerance.

On MSA cards, “best-effort” applies on a channel with highcellDelayVariationToleranceand low ATM bandwidth. Thevalue applied is the same as the range limit on provisionedmaximumBufferDelay on that channel.

On MSA cards this attribute’s value is rounded up to the nearestmultiple of 0.125 ms when applied to the buffer. The range isnominally 0.12 to 63.62 ms, but the upper limit may be reducedby up to 6 ms one a channel with highcellDelayVariationTolerance and low ATM bandwidth.

On4pDS1Aal1 and4pE1Aal1 cards this attribute’s value isrounded up to the nearest multiple of 1 ms when applied to thebuffer. The upper limit is roughly inverse- proportional to theATM bandwidth of the channel.

On the4pDS3ChAal1 card, this attribute’s value is rounded up tothe nearest multiple of 1 ms when applied to the buffer. The rangeis nominally 1 to 32 ms in steps of 1 ms.

Values Decimal (0.01..655.00)autoConfigure

Units msec


ATTRIBUTE Aal1Ces cellDelayVariationTolerance (cdvt)



Description This attribute specifies the maximum time that a cell may arrivelate, compared to a nominal time established at bufferinitialization, without producing errors on the service interface.The nominal time of a cell’s arrival is predicted according to thetime interval required to transmit a cell’s worth of data on the


241-5701-060 2.0S1 Load 2.0.30

service interface.

This attribute’s value is the delay that the Cell Delay VariationTolerance buffer adds to the egress stream immediately after thebuffer initializes. The buffer absorbs variation in the arrival timeof cells from the network, so that a steady stream of data appearson the service interface. If the buffer underflows, due to a latecell, fill-in data is output on the service interface while the bufferre-initializes. When the buffer has re-initialized, normal data isoutput on the service interface and the delay in the buffer isrestored to the value of this attribute.

This attribute must have a value lower than a numeric value ofmaximumBufferDelay. The relationship between this attribute andbufferSize is described under that attribute.

Setting this attribute too low allows traffic with normal CDV tocause unnecessary loss of data on the service interface. Settingthis attribute too high imposes an unnecessarily high propagationdelay on the egress stream.

On MSA cards this attribute’s provisionable range is 0.01..32msand the value applied is rounded up to the nearest multiple of0.125ms.

On4pDS1Aal1 and4pE1Aal1 cards, this attribute’sprovisionable range is strongly dependent on the bandwidth ofthe channel, and the value applied is rounded up to the nearestwhole number of milliseconds, then rounded down to theequivalent number of cells.

Values Decimal (0.01..655.00)

Description This attribute indicates whether the path for this PLC wasdetermined automatically or by static provisioning.NormalpathTypesare selected automatically by Route Selector.The otherpathTypes are both manualpathTypes where the operator mustspecify, through provisioning, a static route termed themanualPath. A manualpathTypeconnection is nearly identical toa normal path type connection with the exception that the route ispre-provisioned. For a manualpathType, bandwidth reservationsare respected along the path exactly as in a normal path. The lasttype, theforcedpathType, is also a manual path but regardless ofthe bandwidth available the route is granted provided the trunksare operational and there are sufficient Logical Channels (LChs).

TheforcedpathTypecould result in over committing the reservedbandwidth allowed on a trunk. A better way to achieve the effectsof a forcedpathType is to use amanualpathType withsetupPriority= 0 andholdingPriority= 0. In this manner the pathwill reserve correct bandwidth and it will bump other paths ifrequired while not being bumped itself.

This attribute applies to the last path failureonly. If a path is no longer up, this may give an indication to thereason that the path has failed. In many cases an alarm will alsobe generated with more specific information. The following is abrief description of the reasons:none - This path has no information for the teardown this istypical of a path provisioned with noremoteName that has notbeen up.normalShutDown - This path has gone down due to normal calltermination.insufficientTxLcOrBandwidth - At present there is either noavailable bandwidth or logical channel numbers available on oneor more of the trunks for this path in the transmit direction.insufficientRxLcOrBandwidth - At present there is either noavailable bandwidth or logical channel numbers available on oneor more of the trunks for this path in the receive direction.trunkFailure - A trunk on the path has failed or has gone downdue to a provisioning change of a critical attribute.trunkCardFailure- A trunk FP card has failed along the path.accessCardFailure- The FP on which the peer access service wasrunning has failed.operatorForced- The path has terminated due to the operatorlocking a trunk along the path.lostLcnClash- The path has terminated because the PA’s at bothends of an intermediate trunk have allocated the same LC todifferent calls. When this happens both calls must go down andthen try to come up again a fraction of a second later (effectivelyensuring that they will now be assigned different LC’s). It isnormal to get the odd clash especially when the PA’s usedLC isapproaching the PA’s maxLC.



networkCongestion - The path has failed due to controlinformation being lost and not recoverable.trunkNotFound - Occurs on amanualpath usually. Check fortrunks not up or names provisioned incorrectly.farEndNotFound - The far end is not provisioned or is not up.Check remote Name.wrongModuleReached - This may occur on amanualpath.Check provisioning for correct trunk and service names.

Re-provision since this is invalid.unknownReason - The failure was not resolved.farEndNotReady - The remote end was reached but theconnection was refused due to the remote end not being enabled.remoteNameMismatch - The remote end has alarmed andrejected this setup due to remoteName provisioning.serviceTypeMismatch - The remote Service Type does not matchthis service type. Check provisioning.reconnectFromFarEnd- The remote end re-established thisconnection. Check the remote endlastTearDownReason todetermine the real reason.bumped - Another call bumped this path from a trunk to getbandwidth (or an LC) which it required to come up. This otherpath had a highersetupPrioritythan this path’sholdingPriorityhence it was allowed to steal the bandwidth (or LC) from thispath.optimized - This call has been rerouted due to the optimizationfeature. The call is still active this just indicates why the pathchanged.trunkOrFarEndDidNotSupportMode - This call was unable tocomplete because a mode required by the service was notsupported by one of the trunks the route went through or by thefar end service it connected to. Currently the only mode that thisapplies to is the map/mux mode on TRUNK PA ATM component.Map mode was required by the application (CES/FrAtm etc.) butwas not available on the TRUNK PA ATM component throughwhich the call was routed or the far end CES/FrAtm component

ATTRIBUTE Aps mode


Description This attribute specifies the protection mode to use. It has possiblevalues ofunidirectional andbidirectional.

Theunidirectional mode allows theAps to decide independentlyof the far end which channel, either working or protection, isactive for receive. For this value, the transmit and receive may beon different channels. Therefore one end may receive from theprotection line while the other end receives from the active line.



Thebidirectional mode instructs theAps to decide jointly withthe far end which channel, either working or protection, is activefor receive.For this value, the transmit and receive is to be on thesame channel. Therefore both the ends receive from the sameline.

Note that if either end is set tounidirectional, the link operates inunidirectional mode.

Note that while anAps Test is being run, theAps operates inunidirectional mode, regardless of the actual provisioned mode.

Values unidirectionalbidirectional

Access Read only

DescriptionThis attribute is not displayed for ATM cards because thephysical layer drops all errored frames at the controller interface.

For all other card types, this attribute is the calculated bit errorrate on the link. Test data are generated and sent in frames of apreset size (frameSize). TheTest component will try to estimatethe number of bit errors in any errored frame which isidentifiable. The statistics will be updated accordingly. A lostframe (may be due to an error on the flag sequence) will bediscarded for the bit error rate calculation. The result is presentedin the form of xEsyy, where x is the mantissa, syy is theexponent, for example 0E+00, 2E-09.Note that thebitErrorRate is an estimate only. For more reliabletest results, the test should be done over a long period. Multipletests would also improve the confidence level of the test results.

Description This attribute specifies the load balancing method for the selectedservice category of the call.

maxAvCr. PNNI routing chooses the path that has the maximumavailable cell rate as the routing path.

random. The routing path is chosen randomly from all theacceptable paths.

avCrProb. The routing path is chosen with a probability inproportion to its available cell rate. This method will result in themore frequent selection of a route having a higher available cellrate over that with a lower available cell rate.

optMetricProb. The routing path is chosen with a probabilityinversely proportional to the optimization metric. This methodwill result in the more frequent selection of a route having thelowest value of the optimization metric over that with a higheroptimization metric.

ATTRIBUTE ARtg Pnni Rf useRouteCaching (useRc)


Description This attribute specifies whether to look in the route cache beforedoing an on-demand route computation.

SettinguseRouteCaching to no causesRouteFinder to use on-demand route computation and displays the resulting list ofcomputed routes. Acceptable paths found in this computation arenot stored in theCache.

SettinguseRouteCachingto yes, and using the same values as theprovisionedLoadBalancing variance attributes, causesRouteFinder to search the cache for an acceptable route beforeperforming an on-demand route computation. The acceptablepaths are displayed and the newly computed routes are stored inthe cache.

SettinguseRouteCaching to yes and applying load balancing onthis iteration of theRouteFinder, uses the regularLoadBalancingminVariance andslopeVariance values since all routes stored inthe cache are within these provisioned multi_path varianceparameters.



Setting theRouteFinder attributes to a different value from theirLoadBalancing counterparts is the same as settinguseRouteCaching to no.

Values noyes

ATTRIBUTE ARtg Pnni Rf rxTrafficDescParm (rxTdp)


Description This attribute is a vector of four traffic parameters whosemeanings are defined by therxTrafficDescType attribute. Thevalues of peak cell rate (PCR) and sustained cell rate (SCR) areexpressed incell/s. Maximum burst size (MBS) is expressed in cells. Thevalue of CDVT is expressed in microseconds. The values of PCR,SCR, MBS and CDVT are used for usage parameter control(UPC).

WhenrxTrafficDescTypeis 1 or 2, all of the parameters must beset to zero (unused).

WhenrxTrafficDescTypeis 3, parameter 1 represents the PCR forCLP0+1 traffic. Parameter 1 must be non-zero. Parameters 2 and3 must be set to zero (unused).

WhenrxTrafficDescTypeis 4, parameter 1 represents the PCR forCLP0+1 traffic; parameter 2 represents the PCR for CLP equal to0 traffic with cell discard. Parameters 1 and 2 must be non-zero.Parameter 3 must be set to zero (unused). Parameter 1 must begreater than or equal to parameter 2.

WhenrxTrafficDescTypeis 5, parameter 1 represents the PCR forCLP0+1 traffic; parameter 2 represents the PCR for CLP equal to0 traffic with cell tagging. Parameters 1 and 2 must be non-zero.Parameter 3 must be set to zero (unused). Parameter 1 must begreater than or equal to parameter 2.

WhenrxTrafficDescriptorType is 3 through8, there are certainextreme combinations ofrxTrafficDescParm which are outsidethe capabilities of the UPC hardware.

To calculate the limits, use the following formulae:I1 = 1 000 000 000 / PCRL1 = CDVT * 1000I2 = 1 000 000 000 / SCRL2 = CDVT + (MBS - 1) * (I2 - I1)I1 and I2 must be less than or equal to 335 523 840. I1 + L1 mustbe less than or equal to 1 342 156 800. I2 + L2 must be less thanor equal to 1 342 156 800. Note that I2 and L2 only apply whentherxTrafficDescriptorType is 6 through8.

If the values of I1, L1, I2 or L2 are closer to the limits describedabove, a further restriction applies. Specifically, if either:I1 > 41 940 480 or



I2 > 41 940 480 orI1 + L1 > 167 769 600 orI2 + L2 > 167 769 600then both I1 and I2 must be greater than 20 480.

Parameter 5 of therxTrafficDescParm is always unused.

If the rxTrafficDescType is sameAsTx, the values in this attributewill be taken from thetxTrafficDescParm.

Description Artg Pnni CacheThis component represents the PNNI Routing Cache. It enhancescall setup performance by providing a call setup request with apreviously computed route from theCache, whenever possible.

TheCache must be populated with previously computed routesbefore it is usable and it reduces the number of on-demand routecomputations once populated.

TheCache stores and maintains entries to several destinationsand uses them to provide suitable routing paths for subsequentcall setup requests. Theclear verb removes allCache entries.

A Cache route entry consists of multiple alternate routes to a

ThenumCrankbackInvalidationsvalue wraps to zero when themaximum value is exceeded or when thetotalEntriesRemovedvalue is exceeded.



If this value is high, it suggests that the route entries in theCacheare becoming invalid during their lifetime. This means that theagingPeriod might have to be decreased. Reroutes due tocrankbacks are resource-intensive and add to network latency.ThereforenumCrankbackInvalidations takes precedence over theavgLifetime status.

Description This attribute specifies the delay before faults detected at the VPlayer are propagated to the VC layer, and thus to the applicationusing the connection.

If the value is 0 (zero), applications using aVirtualPathTerminator are immediately notified of faultsdetected by the VP. Using this value allows these applications tobe advised of faults without requiring loopbacks on eachVcc.Typically, the application goes out of service when advised of afault.

If the value isinfinity , applications are not notified of VP layerfaults. Using this value allows the applications to survivetransient VP layer fault conditions.

The value chosen applies only toVpts andVccs directly beneath aVpt.

Values 0infinity

Default infinity

ATTRIBUTE AtmIf ctdCalculation (ctdCalc)




Description This attribute specifies whether cell transfer delay calculationshould be performed on loopback cells for each SPVC and SPVPconnection under this interface.

Cell transfer delay is calculated as half of the measured segmentround trip delay of a loopback cell.

Cell transfer delay calculation is only supported when segmentswitch side loopback is enabled on the source segment endpoint.Cell transfer delay calculation is only performed on supportedconnections when theaccountCollection attribute of theAtmIfUni or AtmIf Iisp component has a non-empty reason. Celltransfer delay calculation is not provided for connections undertheVpt.

ATTRIBUTE AtmIf txCellMemoryAvailable

Access Read only

Description This attribute is only valid forAtmIf’s on ATM IP FPs. It is notdisplayed forAtmIf’s on other card types.



This attribute indicates the current amount of transmit cellsavailable for thisAtmIf. Transmit cell memory is the memoryavailable for storing ATM cells to be transmitted by connectionsunder thisAtmIf.

ATTRIBUTE AtmIf txCellMemoryCongestionState (txCellCcState)

Access Read only


This attribute indicates the congestion state of the transmit cellmemory for thisAtmIf. It indicates whichtxCellMemoryThreshold corresponds to the current value oftxCellMemoryAvailable.

The congestion state of memory is indicated by a numeric valueranging from 0 to 3. When memory is in a congested state “x”,only traffic with discard priority (DP) < “x” is definitely stillqueued for transmit. Traffic with DP > “x” is definitely discarded.Traffic with DP = “x” may be either queued or discardeddepending on how close the value oftxCellMemoryAvailableis tothe next threshold as displayed intxCellMemoryThreshold. Forexample, CLP1 traffic is queued until the value indicated bytxCellMemoryAvailable reaches the DP3 threshold. At that point,the CLP1 traffic is discarded.

ATTRIBUTE AtmIf txCellMemoryThreshold

Access Read only



241-5701-060 2.0S1 Load 2.0.30

This attribute indicates the transmit cell memory size and threediscard thresholds for thisAtmIf. Transmit cell memory is usedfor storing ATM cells to be transmitted by connections under thisAtmIf.

The first value indicates the total transmit cell memory size. Thisis derived based upon thetxCellMemoryThreshold 0attribute oftheLp/x eng arc aqm/0 componentandLp/x eng arc aqm/0 Ov,and on thetxCellMemory attribute of thisAtmIf.

When thetxCellMemoryAvailable attribute decreases to thesecond value, thetxCellMemoryCongestionState changes from 3to 2. In congestion state 2, traffic with discard priority (DP) > 2 isdiscarded. This threshold is set approximately at 25 percent of thefirst value, the transmit cell memory size.

When thetxCellMemoryAvailable attribute decreases to the thirdvalue, thetxCellMemoryCongestionState changes from 2 to 1. Incongestion state 1, traffic with discard priority (DP) > 1 isdiscarded. This threshold is set approximately at 20 percent of thefirst value, the transmit cell memory size.

When thetxCellMemoryAvailable attribute decreases to thefourth value, thetxCellMemoryCongestionState changes from 1to 0. In congestion state 0, traffic with discard priority (DP) > 0 isdiscarded. This threshold is set approximately at 10 percent of thefirst value, the transmit cell memory size.

The opposite effect occurs when thetxCellMemoryAvailableattribute increases (txCellMemoryCongestionState changes from0 to 3 accordingly).

GROUP AtmIf ConnMap Ov Provisioned (Prov)


Description This group contains provisionable attributes which specify theVCC space to be supported by this ATM interface. The VCCspace consists of an optional “VPI Zero VCC Space” and anoptional “Programmable VCC Space”. If not specified otherwise,the semantic checks described below are applicable only for theCQC-based cards.

The VPI Zero VCC Space is used to support VCCs with a VPI ofzero. The VCI values supported in this space range from 0 to aprovisioned maximum. The size of the VPI Zero VCC Spacemust either be 0 or a multiple of 256. A value of 0 implies that noprogrammable VCCs can be used. In this casenumNonZeroVpisForVccs must also be 0.

The optional Programmable VCC Space is used to support VCCswith a VPI other than zero. The VPI values supported in thisspace must lie in a single contiguous range which excludes VPI0. The VCI values supported in this space range from 0 to aprovisioned maximum. The size of the Programmable VCCSpace (should it exist) must adhere to the following rules:

If (firstNonZeroVpiForVccs = 1) THEN (numNonZeroVpisForVccs + 1) * numVccsPerNonZeroVpi must be a multiple of 256OTHERWISE

numNonZeroVpisForVccs * numVccsPerNonZeroVpi must be a multiple of 256



The number of connection identifier resources in the VCC andVPC space can be determined as follows:

The number of connection identifier resources in the VCC andVPC space (not all of which are available for user connections) isreported in theLp/n Eng Arc totalConnectionPoolAvailableattribute, and can be determined as follows:

IF (numNonZeroVpisForVccs = 0) THEN number of connection ID resources = 256 + numVccsForVpiZeroOTHERWISE IF (firstNonZeroVpiForVccs = 1) THEN number of connection ID resources =

The number of connection identifier resources must not exceedthe capacity of the port to which the interface is linked. If theLphas anEng Arc Cqc Ov component provisioned with a non-zeroconnectionPoolCapacity the port’s capacity is specified by thisattribute. Otherwise the port’s capacity is indicated by theLp/nEng Arc totalConnectionPoolAvailabledivided by the number ofphysical ports on the card.

This attribute is used by the CAC function to compute theequivalent cell rate (ECR) required by a given CBR connection.The larger the value of CDVT, the larger is its ECR.

If Usage Parameter Control (UPC) is enabled for a connection,CDVT is used by the UPC function to decide whether a cell isconforming or non-conforming based on the connection’s trafficdescriptor type. The larger the CDVT value, the more tolerant isthe UPC of bandwidth usage beyond the traffic contract.

Description This attribute specifies the peak-to-peak cell delay variation(CDV) which is contributed to the entire ATM Interface for CBRtraffic.

The CDV is a measure of the delay jitter introduced mostly bytraffic buffering and cell scheduling. The worst case value of thisattribute can be computed as thetxQueueLimitdivided by the linkrate of this ATM Interface.



The value of this attribute is used by PNNI in the ResourceAvailability Information Group (RAIG) topology updates androute selection. It is also used by CAC at connection set-up timeto determine whether this ATM Interface can meet the CDVrequirements of the connection. If so, the value of this attribute isadded to the cumulative CDV field of the extended QoSinformation element.

ATTRIBUTE AtmIf CA Cbr cellLossRatio (clr)


241-5701-060 2.0S1 Load 2.0.30


Criticality Process

Description This attribute specifies the tolerable cell loss ratio (CLR) for CBRtraffic except for connections managed by aVpt CA. The numberis the negative logarithm (base 10) of the CLR. For example, ifthe target CLR = 1E-10 thenCbr cellLossRatio = 10. Thisnumber must be the same as theRtVbr cellLossRatio since CBRand rt-VBR traffic have the same discard priority. TheCbrcellLossRatio is used by the Connection Admission Control(CAC) algorithm to compute the required (equivalent) cell ratefor CBR connections.

There is a trade-off between the service category CLR and theachievable link utilization. To guarantee an excellent servicecategory, the CLR should be as small as possible (e.g., 1E-10).However, a smaller CLR results in a larger equivalent cell rate fora given connection and hence a lower link utilization.

Setting this attribute to 0 means that a CLR of 1 can be tolerated.In this case, no bandwidth is reserved for CBR connections, andCAC is effectively turned off. All CBR connections are admitted.


Default 10

ATTRIBUTE AtmIf CA Cbr txQueueLimit (txql)


Criticality Process

Description This attribute specifies the default maximum queue length for theemission queues used to buffer the traffic of the CBR servicecategory. It is used as the basis for setting the discard thresholdson both common and per-VC queues. For the common queue, thediscard thresholds are set at approximately 35, 75, and 90 percentof the value of this attribute for traffic at discard priority 3(DP=3), DP=2 and DP=1 respectively.

For a per-VC queue, the actual limit may be reduced depending



on the shaping rate of the connection (for standardVpt Vccs, thisis the shaping rate of theVpt). The discard thresholds are set atapproximately 35, 75 and 90 percent of the scaled queue limit fortraffic at discard priority 3 (DP=3), DP=2 and DP=1 respectively.However, a reduction will never result in a value that is less thanthe value set for theminPerVcQueueLimit attribute. CQC-basedATM cards and 1pOC12SmLrAtm cards do not support per-VCqueues at the CBR service category.

ATTRIBUTE AtmIf CA Cbr minPerVcQueueLimit (minpervcql)


Criticality Process

Description This attribute specifies the minimum queue limit for the per-VCqueues of connections of the CBR service category.

This attribute is ignored on CQC-based ATM cards,1pOC48SmSrAtm, and 1pOC12SmLrAtm cards, because they donot support per-VC queues at the CBR service category.

The queue limit of a per-VC queue is obtained by scaling downthetxQueueLimit based on the shaping rate of that queue(shaping rate for the connection, and for standardVpt Vccs, theshaping rate of theVpt). This produces a constant delay forvarious queue lengths. ThetxQueueLimit provides an upperbound whileminPerVcQueueLimit provides the lower bound.The value of this attribute must not be greater than the value ofthetxQueueLimit attribute. If this service category is used byTrunks the value ofminPerVcQueueLimit must be at least 88.

For Vpts, this attribute does not apply. Regardless ofVpt servicecategory, standardVpts always use theAtmIf Ca NrtVbrminPerVcQueueLimitvalue as their default. To determine thequeue limit of a standardVpt Vcc, thetxQueueLimit is scaleddown by theVpt shaping rate.

ATTRIBUTE AtmIf CA Cbr emissionPriority (ep)


Criticality Process

Description This attribute is not applicable and is ignored for CQC-basedATM cards.

This attribute specifies the emission priority (EP) which is used totransmit traffic of the CBR service category. A lower numericalvalue for this attribute specifies a higher emission priority. 0 is thehighest EP and 7 is the lowest. Cells at a higher emission priorityreceive higher preference for link bandwidth. EPs 0 and 1 are inthe absolute priority range, and are unaffected by any minimum



bandwidth guarantees. EPs 2 through 7 are in the guaranteedbandwidth range. Minimum bandwidth guarantee is specified intheAtmIf/n Ep/m component.

Emission priority setting must comply with all of the followingconstraints:1. The emission priority numbers must be in the following order:CBR <= rt-VBR <= nrt-VBR <= ABR <= UBR2. Two different ATM service categories may share the same EPonly if they are both shaped.3. CBR and rt-VBR may be placed either in the absolute priorityrange (EP 0 or 1) or in the guaranteed bandwidth range (EP 2through 7).4. If both CBR and rt-VBR are shaped, rt-VBR must share thesame EP with CBR or ABR. If either one of CBR or rt-VBR arenot shaped, then they cannot share the same EP.5. ABR service category is always deemed to be shaped. If nrt-VBR is shaped, it must share the same EP with ABR. If nrt-VBRis not shaped it must have a higher EP than ABR.6. If UBR is shaped, it must share the same EP with ABR. IfUBR is not shaped, it must have a lower EP than ABR.

If the Vcc Tm, Vpc Tm, orVpt Tm, txTrafficDescType indicatestype 1 or 2, this attribute is ignored, and traffic shaping is notapplicable for that connection.

When this attribute is set toinverseUpc, traffic shaping for aconnection is enabled according to the value of theVcc Tm, VpcTm,or Vpt Tm txTrafficDescType.

If this attribute is set toinverseUpc, and thetxTrafficDescType is3, 4, or 5, linear traffic shaping is enabled. Linear traffic shapinguses a single static traffic shaping rate.

If this attribute is set toinverseUpc, and thetxTrafficDescType is6, 7, or 8, inverse-UPC (also referred to as VBR or dual leakybucket) traffic shaping is enabled. Inverse-UPC traffic shapingcan burst above the sustained cell rate to the peak cell rate for theduration defined by maximum burst size.

ATTRIBUTE AtmIf CA Cbr shapeRecoupPolicy (recoup)




Criticality Process

Description This attribute specifies the shaping recoup policy for the CBRservice category. This is the policy which is used to recoupshaping opportunities which are lost when more than oneconnection schedules a cell for the same transmit opportunity. Inthis case, one connection is scheduled, and the cell from the otherconnection is delayed by one cell time. This attribute affects howthe transmit time is calculated for the next cell on the delayedconnection. This attribute is ignored if this service category is notshaped.

When the connection which was delayed schedules the next cellto transmit, it may calculate the time as a difference from eitherthe previous actual cell transmit time, or the time when theprevious cell should have been transmitted.

Setting this attribute tomaximumEfficiency results in eachconnection trying to recoup or regain any delays in scheduling.The transmit time from the next cell is calculated from the timewhen the cell should originally have been sent. Cell delayvariation (CDV) occurs in this case since the cells are sent withless than the shaping delay between them. However, in generalthe shaper recovers (recoups) lost opportunities and improvesefficiency.

Setting this attribute tominimumCdv results in connections nottrying to recoup or regain any delays in scheduling. The transmittime for the next cell is calculated from the time when theprevious cell was actually transmitted. This minimizes CDV, butresults in missed cell opportunities.

ATTRIBUTE AtmIf CA Cbr weightPolicy


Criticality Process



Description This attribute specifies the default policy which is applied whencalculating the fairness weight for unshaped connections of theCBR service category. The fairness weight for a connectiondetermines the relative amount of bandwidth which thatconnection obtains, compared to other connections in the sameservice category. Connections with equal weight get equaltransmit opportunities. Connections with higher weights get moretransmit opportunities compared with connections that havelower weights. An override to this default may be specified for aprovisioned connection under theVcd Tm or Vpd Tm component.

The fairness weight for a connection is directly proportional tothe value of one of the traffic descriptor parameters for thatconnection. This attribute specifies which traffic descriptorparameter is used for connections of the CBR service category.

This attribute is ignored on CQC-based ATM cards. This attributeis also ignored on ATM IP cards ifunshapedTransmitQueueingisset for common queuing.

If this attribute is set toscr, the fairness weight is proportional tothe transmit sustained cell rate (SCR) of a connection.Connections with a higher SCR have a higher fairness weight.For connections withtxTrafficDescType 3, which have no SCR,the sustained cell rate is assumed to be equal to the peak cell rate.

If this attribute is set topcr, the fairness weight is proportional tothe transmit peak cell rate (PCR) of a connection. Connectionswith a higher PCR have a higher fairness weight. Connectionswith txTrafficDescType 1 or 2 get a minimum weight, which is 1.

If this attribute is set toecr, the fairness weight is proportional tothe equivalent cell rate (ECR) of a connection as calculated byconnection admission control (CAC). Connections with a higherECR have a higher fairness weight. Connections with an ECR of0 get a minimum weight, which is 1.

ATTRIBUTE AtmIf CA RtVbr cellLossRatio (clr)


Criticality Process

Description This attribute specifies the tolerable cell loss ratio (CLR) for rt-VBR traffic except for connections managed by aVpt CA. Thenumber is the negative logarithm (base 10) of the CLR. Forexample, if the target CLR = 1E-10 thenRtVbr cellLossRatio =10. This number must be the same as theCbr cellLossRatio sinceCBR and rt-VBR traffic have the same discard priority. TheRtVbr cellLossRatio is used by the Connection AdmissionControl (CAC) algorithm to compute the required (equivalent)cell rate for rt-VBR connections. This number must be less thanor equal to theNrtVbr cellLossRatio, since rt-VBR traffic has ahigher discard priority.


Setting this attribute to 0 means that a CLR of 1 can be tolerated.In this case, no bandwidth is reserved for rt-VBR connections,and CAC is effectively turned off. All rt-VBR are admitted.

ATTRIBUTE AtmIf CA NrtVbr cellLossRatio (clr)


Criticality Process

Description This attribute specifies the tolerable cell loss ratio (CLR) for nrt-VBR traffic except for connections managed by aVpt CA. Thenumber is the negative logarithm (base 10) of the CLR. In otherwords if the target CLR = 1E-10 thenNrtVbr cellLossRatio = 10.This number must be greater than or equal toRtVbr cellLossRatiosince rt-VBR traffic has a higher discard priority. TheNrtVbrcellLossRatio is used by the Connection Admission Control(CAC) algorithm to compute the required (equivalent) cell ratefor nrt-VBR connections.


Setting this attribute to 0 means that a CLR of 1 can be tolerated.In this case no bandwidth is reserved for nrt-VBR connections,and CAC is effectively turned off. All nrt-VBR connections areadmitted.

ATTRIBUTE AtmIf CA NrtVbr txQueueLimit (txql)


Criticality Process

Description This attribute specifies the default maximum queue length for theemission queues used to buffer the traffic of the nrt-VBR servicecategory. It is used as the basis for setting the discard thresholdson both common and per-VC queues. For the common queue, thediscard thresholds are set at approximately 35, 75, and 90 percentof the value of this attribute for traffic at discard priority 3(DP=3), DP=2, and DP=1 respectively.

For per-VC queue, the actual limit may be reduced depending onthe shaping rate of the connection (for standardVpt Vccs, this isthe shaping rate of theVpt). The discard thresholds are set atapproximately 35, 75, and 90 percent of the scaled queue limitfor traffic at discard priority 3 (DP=3), DP=2, and DP=1respectively. However, a reduction will never result in a value thatis less than the value set for theminPerVcQueueLimitattribute.

When the value of this attribute isautoConfigure, an appropriatevalue is selected based on the card type. It is set to 1792 for lowspeed cards such as DS1, E1, and IMA, set to 2304 for highspeed CQC-based ATM cards such as JT2, DS3, E3 and OC3,and set to 10240 for high speed ATM IP cards such as3pDS3Atm2, 3pE3Atm2, 2pOC3SmAtm2 and 2pOC3MmAtm2.

ATTRIBUTE AtmIf CA NrtVbr minPerVcQueueLimit (minpervcql)


Criticality Process

Description This attribute specifies the minimum queue limit for the per-VCqueues of connections of the nrt-VBR service category.

The queue limit of a per-VC queue is obtained by scaling downthetxQueueLimitbased on the shaping rate of that queue(shaping rate for the connection, and for standardVpt Vccs, theshaping rate of theVpt). This produces a constant delay forvarious queue lengths. ThetxQueueLimit provides an upperbound whileminPerVcQueueLimitprovides the lower bound.The value of this attribute must not be greater than the value ofthetxQueueLimit attribute. If this service category is used byTrunks the value ofminPerVcQueueLimit must be at least 88.

On CQC-based ATM cards, this attribute must be set to the same

Criticality Process

Description This attribute specifies the default Rate Decrease Factor (RDF)for ABR connections. An override to this default may bespecified for a provisioned connection under theVcd Tm AbrorVpd Tm Abr component, or signalled in the ABR SetupParameters Information Element.

The RDF value is computed by using the provisioned value ofthis attribute, n, as 2 to the inverse power n. For example, if thevalue of this attribute is8, RDF is 2E-8 = 1/256.

RDF controls the amount by which the cell transmission rate maydecrease upon receipt of a backward Resource Management (B-RM) cell. For example, if a backward RM cell is received withthe Congestion Indication (CI) field set to 1, the Allowed CellRate (ACR) value would be reduced by the amount (RDF*ACR).The ACR is not allowed to fall below the Minimum Cell Rate(MCR), in which case the ACR is set to MCR.

CDF controls the decrease in the Allowed Cell Rate (ACR)associated with the CRM parameter. CRM is the limit of thenumber of forward Resource Management (F-RM) cells whichmay be sent in the absence of received backward RM cells. Whenthis limit is crossed, the ACR value would be decreased by theamount (CDF*ACR). The ACR is not allowed to fall below theMCR, in which case the ACR is set to MCR.

ADTF is the time interval permitted between sending forwardResource Management (F-RM) cells before the Allowed CellRate (ACR) is decreased to the Initial Cell Rate (ICR). In otherwords, if the source does not transmit a forward RM cell for aperiod of ADTF centi-seconds (hundredths of a second), it willreduce its ACR to the value of its ICR. If ACR is already at orbelow ICR, further rate reductions are defined by the CRM ABRparameter.

ATTRIBUTE AtmIf CA Abr dgcraMaximumDelay (dgcraMaxDelay)


Criticality Process

Description This attribute specifies the default maximum delay for DynamicGeneral Cell Rate Algorithm (DGCRA) rate changes for ABRconnections. An override to this default may be specified for aprovisioned connection under theVcd Tm Abror Vpd Tm Abrcomponent.

This attribute specifies an upper bound on the delay after whichthe rate change induced by a backward Resource Management(B-RM) cell departing from this interface (in the backwarddirection) is expected to be observed at the interface (in theforward connection).

This upper bound may be approximated as the round trip sum ofthe fixed and propagation delays and the maximum queueingdelays between the ABR source and this interface.

The value of this attribute is used in policing an ABR connectionusing the DGCRA. A larger value for this attribute implies amore lenient policer. When there is a decrease in the Allowed



Cell Rate (ACR), the policer waits a correspondingly longerperiod of time before it enforces the new cell rate.

The value of this attribute must be greater than or equal todgcraMinimumDelay, since the maximum delay must be greaterthan or equal to the minimum delay.

ATTRIBUTE AtmIf CA Abr dgcraMinimumDelay (dgcraMinDelay)


Criticality Process

Description This attribute specifies the default minimum delay for DynamicGeneral Cell Rate Algorithm (DGCRA) rate changes for ABRconnections. An override to this default may be specified for aprovisioned connection under theVcd Tm Abror Vpd Tm Abrcomponent.

This attribute specifies a lower bound on the delay after which therate change induced by a backward Resource Management (B-RM) cell departing from this interface (in the backward direction)is expected to be observed at the interface (in the forwardconnection).

This lower bound may be approximated as the round trip sum ofthe fixed and propagation delays between the ABR source andthis interface.

The value of this attribute is used in policing an ABR connectionusing the DGCRA. A smaller value for this attribute implies amore lenient policer. When there is an increase in the AllowedCell Rate (ACR), the policer waits for a correspondingly shorterperiod of time before it enforces the new cell rate.

The value of this attribute must be less than or equal to

ATTRIBUTE AtmIf CA Ubr minPerVcQueueLimit (minpervcql)


Criticality Process

Description This attribute specifies the minimum queue limit for the per-VCqueues of connections of the UBR service category.

The queue limit of a per-VC queue is obtained by scaling downthetxQueueLimit based on the shaping rate of that queue(shaping rate for the connection, and for standardVpt Vccs, theshaping rate of theVpt). This produces a constant delay forvarious queue lengths. ThetxQueueLimit provides an upperbound whileminPerVcQueueLimitprovides the lower bound.The value of this attribute must not be greater than the value ofthetxQueueLimit attribute. If this service category is used byTrunks the value ofminPerVcQueueLimit must be at least 88.

ATTRIBUTE AtmIf CA Ubr shapeRecoupPolicy (recoup)


Criticality Process

Description This attribute specifies the shaping recoup policy for the UBRservice category. This is the policy which is used to recoupshaping opportunities which are lost when more than oneconnection schedules a cell for the same transmit opportunity. Inthis case, one connection is scheduled, and the cell from the otherconnection is delayed by one cell time. This attribute affects howthe transmit time is calculated for the next cell on the delayedconnection. This attribute is ignored if this service category is notshaped.



Setting this attribute tominimumCdv results in connections nottrying to recoup or regain any delays in scheduling. The transmittime for the next cell is calculated from the time when theprevious cell was actually transmitted. This minimizes CDV, but



results in missed cell opportunities.

ATTRIBUTE AtmIf CA Ubr unshapedTransmitQueueing (unshap)


Criticality Process

Description This attribute specifies the default queuing option for unshapedconnections of the UBR service category. This attribute controlswhether common or per-VC queueing is used.


Common queueing means that cells are queued in First In FirstOut order on a common queue. The common queue has one set ofcongestion control levels for all cells enqueued on it. For ATM IPcards, there is one common queue for the UBR service category.For CQC-based ATM cards, there is one common queue which isshared by the nrt-VBR, ABR and UBR service categories.

For 1pOC12SmLrAtm cards this attribute must be set tocommonor autoConfigure. This attribute cannot be set toperVc since per-Vc queueing is not available on the 1pOC12SmLrAtm card. ThevalueautoConfigure is interpreted to meancommon queueing.

For ATM IP cards, if traffic shaping for this service category isdisabled, this attribute may take any of the three values. In thiscase, the valueautoConfigure is interpreted to mean per-VCqueueing.

ATTRIBUTE AtmIf CA Ubr weightPolicy


Criticality Process

Description This attribute specifies the policy which is applied whencalculating the fairness weight for unshaped connections of theUBR service category. The fairness weight for a connectiondetermines the relative amount of bandwidth which thatconnection obtains, compared to other connections in the sameservice category. Connections with equal weight get equaltransmit opportunities. Connections with higher weights get moretransmit opportunities compared with connections that havelower weights. An override to this default may be specified for aprovisioned connection under theVcd Tm or Vpd Tm component.

The fairness weight for a connection is directly proportional tothe value of one of the traffic descriptor parameters for thatconnection. This attribute specifies which traffic descriptorparameter is used for connections of the UBR service category.

Description This attribute contains the current state of the receive side OAMcell congestion for this connection. Its value reflects whether therate of received OAM cells for this connection is below aspecified threshold. The connection maintains a count of thenumber of OAM cells which are terminated per second. Once thatcount exceeds the specified threshold, extraction of all OAM cellsfor this connection is disabled for a period of one minute. This isa congestion management mechanism to prevent the processorfrom being overloaded with handling OAM cells for a particularconnection. This mechanism ensures that tasks, such as trunksobtain enough processor cycles to remain in service, and are notadversely affected by excessive rate of OAM cells on a particularconnection.

The value isgood when the rate of received OAM cells is lessthan the allowed threshold.

The value isbad when the arrival rate has exceeded the allowedthreshold. It remainsbadfor one minute, before returning togoodagain. During this timeout, extraction of all OAM cells isdisabled for this connection. As a result, other loopback failureconditions may occur.

The value isunknownwhen the application has not yet begun touse this connection. An example is theTest component before atest has been started.



Each type of OAM cell is counted separately. The threshold forAIS cells is three cells per second. If more than three AIS cellsare received within a one second interval, this attribute is set tobad. The threshold for RDI cells and each loopback type is alsothree, but the threshold for trace cells is 250 per second.

The state of this attribute has no direct effect on the value of theoperStatus attribute or on the number of troubled connections.

TheconstantBitRate service category is intended for real timeapplications, that is those requiring tightly constrained delay anddelay variation, as would be appropriate for voice and videoapplications. The consistent availability of a fixed quantity ofbandwidth is considered appropriate for CBR service. Cellswhich are delayed beyond the value specified by Cell TransferDelay are assumed to be of significantly reduced value to theapplication.

ThertVariableBitRate service category is intended for real timeapplications, that is those requiring tightly constrained delay anddelay variation, as would be appropriate for voice and videoapplications. Sources are expected to transmit at a rate whichvaries with time. Equivalently, the source can be described as“bursty”. Cells which are delayed beyond the value specified byCTD are assumed to be of significantly reduced value to theapplication. Real time VBR service may support statisticalmultiplexing of real time sources.

ThenrtVariableBitRate service category is intended for non-realtime applications which have bursty traffic characteristics andwhich can be characterized in terms of a PCR, SCR, and MBS.For those cells which are transferred within the traffic contract,the application expects a low cell loss ratio. For all connections, itexpects a bound on the mean cell transfer delay. Non-real timeVBR service may support statistical multiplexing of connections.

TheavailableBitRate service is an ATM layer service categoryfor which the limiting ATM layer transfer characteristicsprovided by the network may change subsequent to connectionestablishment. ABR service has a flow control mechanism whichsupports several types of feedback to control the source rate inresponse to changing ATM layer transfer characteristics.

ATTRIBUTE AtmIf Vpc Vpd Tm txPacketWiseDiscard (txpd)


241-5701-060 2.0S1 Load 2.0.30



Description This attribute specifies whether packet-wise discard functions areto be enabled or disabled in the transmit data direction for thisconnection. Packet-wise discard functions should only berequested if this connection is transferring AAL5 frame traffic.This attribute is not applicable forVpts.

Packet-wise functions increase the “goodput” of the link. Thetransmit packet-wise functions are Early Packet Discard (EPD)and Partial Packet Discard (PPD).

EPD allows the connection to discard an entire frame once thetransmit queue has reached the EPD threshold. EPD increases the“goodput” of a link, since discarding an entire frame means thatsome queue capacity is guarded for some other frame which isalready partially transmitted. All cells of the frame are discardedfrom the Beginning of Message (BOM) cell up to and includingthe End of Message (EOM) cell.

PPD allows the connection to discard the remainder of a cell-forwarded AAL5 frame if one cell of this frame has beendiscarded. All cells are discarded up to but not including theEOM cell. The PPD function increases the “goodput” of the link,since cells which are only going to be discarded at the AAL5reassembly point are not transmitted.

On CQC-based ATM cards, the packet-wise discard functions arePPD and EPD. PPD is available at VCC cell-transfer points. PPDis not applicable at frame-cell conversion points, and is notapplicable forVpcs. PPD is configured by this attribute. Packet-wise discard should only be enabled for connections carryingAAL5 segmentation traffic. Setting the value toenabledfor anyother traffic type may result in all traffic being discarded. OnCQC-based ATM FPs, EPD is automatically enabled at frame-to-cell conversion points, independent of the setting of this attribute.

On CQC-based ATM cards, at a permanent VCC connectionendpoint, this attribute is not applicable and is ignored. If AAL5



segmentation and reassembly has been requested, PPD and EarlyPacket Discard (EPD) are automaticallyenabled.

On ATM IP cards, packet-wise discard functions include EPDand PPD. PPD and EPD apply to individual VCCs and VCCswithin VPCs at all connection points, including tandem VPCconnections. Both PPD and EPD are controlled by this attribute.This attribute may safely be set toenabled for any connection(Vcc or Vpc) on ATM IP FPs since they have the ability toautomatically detect AAL5-segmented traffic on a connection,and only enable packet-wise discards if AAL5-segmented trafficis detected.

When this attribute is set toenabled, packet-wise discardfunctions are applied to transmit traffic at this connection point.When this attribute is set todisabled, packet-wise discardfunctions are not applied to transmit traffic at this connectionpoint.

At a SPVC origin on a PNNI interface, a value ofenabledspecifies that frame discard is requested in the backwarddirection. When this attribute is set todisabled, backward framediscard is not requested in the SPVC call setup.

The transmit packet-wise discard functions that are active arevisible in theVcc/Vpc Tm txPacketWiseDiscard operationalattribute.

ATTRIBUTE AtmIf Vpc Vpd Tm rxPacketWiseDiscard (rxpd)



Description This attribute specifies whether packet-wise discard functions areto be enabled or disabled in the receive data direction for thisconnection. Packet-wise discard functions should only berequested if this connection is transferring AAL5 frame traffic.


241-5701-060 2.0S1 Load 2.0.30

This attribute is not applicable forVpts.

Packet-wise functions increase the “goodput” of the link. Thereceive packet-wise function is Partial Packet Discard (PPD).

PPD allows the connection to discard the remainder of a cell-forwarded AAL5 frame if one cell of this frame has beendiscarded, for example due to UPC. All cells are discarded up tobut not including the EOM cell. The PPD function increases the“goodput” of the link, since cells which are only going to bediscarded at the AAL5 reassembly point are not transmitted.

PPD is available at all VCC connection points where UPC maybe activated. PPD is not applicable forVpcs.

On CQC-based ATM FPs, packet-wise discards should only beenabled for connections carrying AAL5 segmentation traffic.Setting the value toenabledfor any other traffic type may resultin traffic being discarded.

On CQC-based ATM cards, at a permanent VCC connectionendpoint, this attribute is not applicable and is ignored. If AAL5segmentation and reassembly has been requested, PPD and EarlyPacket Discard (EPD) are automaticallyenabled.

On ATM IP cards, this attribute may safely be set toenabled forany connection (Vcc or Vpc) since they have the ability toautomatically detect AAL5-segmented traffic on a connection,and only enables packet-wise discards if AAL5-segmented trafficis detected.

When this attribute is set toenabled, packet-wise discardfunctions are applied to receive traffic at this connection point.When this attribute is set todisabled, packet-wise discardfunctions are not applied to receive traffic at this connectionpoint.

At a SPVC origin on a PNNI interface, a value ofenabledspecifies that frame discard is requested in the forward direction.When this attribute is set todisabled, forward frame discard isnot requested in the SPVC call setup.

ATTRIBUTE AtmIf Vpc Vpd Tm abrConnectionType (abrType)



Description This attribute specifies the type of ABR behavior which is to beenforced at this connection. This attribute is only applicable if theatmServiceCategory attribute isavailableBitRate. If theatmServicecategory attribute is notavailableBitRate, thisattribute value is ignored.

The actual ABR functionality which is in effect is visible in theVcc/Vpc/Vpt TmabrConnectionType operational attribute.

For CQC-based ATM cards, the only allowable values aresameAsCa, nonAbrInterworking or abrSwitch. If abrSwitch isselected, the CQC implements EFCI marking behavior.

For the 1pOC12SmLrAtm card, the only allowable values aresameAsCa or abrSwitch.If abrSwitch is selected, EFCI markingbehavior is implemented.

sameAsCa is used to request the default behavior as specified intheCA Abr component for thisVcc. Otherwise, this attributeoverrides the default behavior.

virtualSourceDest is used to request that this connection pointfunction as a virtual source/virtual destination. VS/VDfunctionality is only supported on ATM IP FPs.

sourceDest requires that this connection point function as a S/Dfor RM cells. S/D mode is automatically invoked at this

connection point either if this is a connection end point, or if thenext hop connection point is configured asnonAbrInterworking.

nonAbrInterworking is used to request that this connection pointfunction as an interworking between ABR and non-ABR servicecategories. This means that there are no RM cells on the link sideof this connection, and that the next hop connection point isperforming as an ABRsourceDest.

abrSwitch is used to request ABR switch behavior for thisconnection point. The ABR switch behavior is first, to confirm tovirtualSourceDest or nonAbrInterworking setting on the nexthop, and otherwise to implement ABR ER switch behavior. ForCQC-based FPs, ABR switch behavior is implemented as EFCImarking.

Parameter 1 must be non-zero and must be greaterthan or equal to parameter 3. Parameter 3 may be optionally zero.

Whenever it is valid for PCR to be specified, parameter 5 mayalso be used to specify a requested shaping rate. A non-zero valuein parameter 5 overrides the value in parameter 1 and is used asthe peak cell rate in calculations of CAC and shaping rate. WhentheatmServiceCategory is availableBitRate (ABR), the shapingrate is dynamically chosen, based on the ABR flow controlmechanism, as a value between the MCR and the PCR or therequested shaping rate if applicable.

For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped atthe next available shaping rate less than the PCR.

For txTrafficDescType 6, 7 and 8 if linear traffic shaping is



selected, the transmit traffic is shaped at the highest available ratewhich is between PCR and SCR. However, if there is no availableshaping rate between PCR and SCR, traffic is shaped at the nextrate above the PCR.

For txTrafficDescType6, 7 and 8 if inverse-UPC traffic shaping isselected, the transmit traffic is shaped at a variable rate whichconforms to the PCR, SCR and MBS of the connection trafficdescriptor. Inverse-UPC traffic shaping is available only on ATMIP cards.

WhenrxTrafficDescType is any value from 3 through 8,parameter 4 represents the CDVT.

If the value of CDVT either in parameter 2 or in parameter 4 iszero, the CDVT is taken from theCAdefaults for the particularatmServiceCategory of this connection.



On a CQC-based ATM card, whenrxTrafficDescriptorType is 3through 8, there are certain extreme combinations ofrxTrafficDescParm which are outside the capabilities of the UPChardware. Thecheck prov command detects such cases andgenerates an error message. If this happens, adjust the parametersuntil they fall within the supported limits.

To calculate the limits, use the following formulae:I1 = 1 000 000 000 / PCRL1 = CDVT * 1000I2 = 1,000,000,000 / SCRL2 = CDVT + (MBS - 1) * (I2 - I1)I1 and I2 must be less than or equal to 335,523,840. I1 + L1 mustbe less than or equal to 1,342,156,800. I2 + L2 must be less thanor equal to 1,342,156,800. Note that I2 and L2 only apply whentherxTrafficDescriptorType is 6 through 8.

If the values of I1, L1, I2 or L2 are closer to the limits describedabove, a further restriction applies. Specifically, if either:I1 > 41,940,480 orI2 > 41,940,480 orI1 + L1 > 167,769,600 orI2 + L2 > 167,769,600then both I1 and I2 must be greater than 20,480.


If the rxTrafficDescType is sameAsTx, the values provisioned inthis attribute are ignored. The traffic parameters for the receivedirection are taken from thetxTrafficDescParm.

RDF controls the amount by which the cell transmission rate maydecrease upon receipt of a backward Resource Management(RM) cell. For example, if a backward RM cell is received withthe Congestion Indication (CI) field set to 1, the Allowed CellRate (ACR) value would be reduced by the amount (RDF*ACR).The ACR is not allowed to fall below the Minimum Cell Rate(MCR), in which case the ACR is set to MCR.

Description This attribute specifies an upper bound on the delay after whichthe rate change induced by a backward Resource Management(RM) cell departing from this connection point (in the backwarddirection) is expected to be observed at this connection point (inthe forward direction).

This upper bound may be approximated as the sum of the roundtrip fixed and propagation delays and the maximum queuingdelays between the ABR source and this interface.

The value of this attribute is used in policing an ABR connectionusing the Dynamic General Cell Rate Algorithm (DGCRA). Alarger value for this attribute implies a more lenient policer.When there is a reduction in the Allowed Cell Rate (ACR), thepolicer waits for a correspondingly longer period of time before itenforces at the new cell rate.

Description This attribute shows the amount by which the bandwidth has beenreduced for this connection. This value is non-zero only forconnections which havebandwidthElastic displayed asyes, andwhich are also operating in a reduced bandwidth mode. This istypically the case for selected connections running over an IMAlink. This attribute takes a value from 0 (no reduction) up to theECR. For all connections which are running at their full allocatedbandwidth,bwReduction has the value 0. Connections whichhave been reduced in allocated bandwidth have a positive numberfor this attribute.

TheTest componentrequires exclusive use of its parentVcc and cannot co-exist with


241-5701-060 2.0S1 Load 2.0.30

other ATM service components (such asNep, Nrp, andLoop).

An ATM connection test circulates traffic through a VCC havingaTestcomponent at one end and the other end configured to loopback ATM cells. TheTest component generates test frames,transforms them into ATM cells using AAL5 segmentation, andtransmits them through the VCC; the returned cells are receivedby theTest component, reassembled back into frames, and theframes are consumed.

The test frames generated by the test are grouped into twoindependent streams.1) The loading frame stream circulates a set of “loading frames”through the connection as rapidly as possible. The intent of thisstream is to verify the operation of the connection under acontrolled load.2) The verification stream transmits a series of “verificationframes” through the connection; as each frame is returned, theTest component verifies its contents and the next verificationframe in the series is transmitted. The intent of this stream is toverify that frames are not being corrupted.The test can be configured to send frames from either or bothstreams. The size and content of the test frames can also becontrolled.

ATTRIBUTE AtmIf Vcc Test bandwidthElastic (bwElastic)




Description This attribute specifies whether the connection (VCC) should beconfigured with elastic bandwidth or not. Elastic bandwidth is ofimportance in conjuction with IMA links, where some links failand the resulting bandwidth is less than the requested bandwidthfor all connections. In that case, some connections may bereduced in bandwidth based on the setting of thebwElasticattribute.

If this attribute is set toyes, the Test application signals to theconnection that the bandwidth for this connection is elastic, andmay be reduced in the case of IMA link failures. If the bandwidthis reduced, the rate of test cells which can be handled by theconnection will also be reduced.

If this attribute is set tono, the Test application signals to theconnection that the bandwidth for this connection must bemaintained at the requested level. If the connection cannotmaintain the full bandwidth, the connection may be released(cleared) based on the holding priority of the connection.

In that case, someconnections may be released based on the connection’s holdingpriority.

Zero (0) is the highest holding priority, andfour (4) is the lowestpriority. A setting ofzero to four overrides whatever holdingpriority that has been configured at the connection (VCC). Asetting ofnoOverride means that the connection should use itsinternally configured holding priority.

Access Read only

Description This attribute indicates the ATM service category used for trafficin both directions of the connection.

TheconstantBitRate service category is intended for real timeapplications, that is, those requiring tightly constrained delay anddelay variation, as would be appropriate for voice and videoapplications. The consistent availability of a fixed quantity ofbandwidth is considered appropriate for CBR service. Cellswhich are delayed beyond the value specified by Cell TransferDelay are assumed to have significantly reduced value for theapplication.


241-5701-060 2.0S1 Load 2.0.30

ThertVariableBitRate service category is intended for real timeapplications; that is those requiring tightly constrained delay anddelay variation, as would be appropriate for voice and videoapplications. Sources are expected to transmit at a rate whichvaries with time. Equivalently, the source can be described as“bursty”. Cells which are delayed beyond the value specified byCell Transfer Delay are assumed to be of significantly reducedvalue to the application. Real time VBR service may supportstatistical multiplexing of real time sources.



TheunspecifiedBitRateservice is intended for non-real timeapplications, that is those not requiring tightly constrained delayand delay variation. UBR sources are expected to be bursty. UBRservice supports a high degree of statistical multiplexing amongsources. UBR service does not specify traffic related serviceguarantees. No numerical commitments are made with respect tothe cell loss ratio experienced by a UBR connection, or as to thecell transfer delay experienced by cells on the connection.

Description This attribute is a vector of five traffic parameters whosemeanings are defined by thetrafficDescTypeattribute. The valuesof peak cell rate (PCR), sustained cell rate (SCR) and requestedshaping rate are expressed in cell/s. Maximum burst size (MBS)is expressed in cells. CDVT is expressed in microseconds. Thevalues of PCR, SCR, MBS and CDVT are used for connectionadmission control (CAC). The value of CDVT is only used forconnections where theatmServiceCategory is constantBitRate.For all other values ofatmServiceCategory, CDVT is ignored.The values of PCR, SCR and requested shaping rate are used todetermine the actual shaping rate where traffic shaping isenabled.

WhentrafficDescTypeis 3, parameter 1 represents the PCR forCLP equal to 0 and 1 traffic; parameter 4 represents the CDVT;and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1.This result is used as the PCR. Parameter 1 must be non-zero.Parameters 2 and 3 must be zero.

WhentrafficDescTypeis 6, parameter 1 represents the PCR forCLP equal to 0 and 1 traffic; parameter 2 represents the SCR forCLP equal to 0 and 1 traffic; parameter 3 represents the MBS forCLP equal to 0 and 1 traffic; parameter 4 represents the CDVT;and parameter 5 represents the requested shaping rate. A non-zero value in parameter 5 overrides any value in parameter 1.This result is used as the PCR. Parameters 1, 2, and 3 must benon-zero. Parameter 1 must be greater than or equal to parameter2. Parameter 5 must either be zero (unused) or greater than orequal to parameter 2.

WhentrafficDescTypeis 7, parameter 1 represents the PCR forCLP equal to 0 and 1 traffic; parameter 2 represents the SCR forCLP equal to 0 with cell discard; parameter 3 represents the MBSfor CLP equal to 0 traffic; parameter 4 represents the CDVT; andparameter 5 represents the requested shaping rate. A non-zero



value in parameter 5 overrides any value in parameter 1. Thisresult is used as the PCR. Parameters 1, 2, and 3 must be non-zero. Parameter 1 must be greater than or equal to parameter 2.Parameter 5 must either be zero (unused) or greater than or equalto parameter 2.

WhentrafficDescTypeis 8, parameter 1 represents the PCR forCLP equal to 0 and 1 traffic; parameter 2 represents the SCR forCLP equal to 0 traffic with cell tagging; parameter 3 representsthe MBS for CLP equal to 0 traffic; parameter 4 represents theCDVT; and parameter 5 represents the requested shaping rate. Anon-zero value in parameter 5 overrides any value in parameter 1.This result is used as the PCR. Parameters 1, 2, and 3 must benon-zero. Parameter 1 must be greater than or equal to parameter2. Parameter 5 must either be zero (unused) or greater than orequal to parameter 2.


For trafficDescType3 the traffic is shaped at the next rate lessthan the PCR.

For trafficDescType6, 7, and8, the traffic is shaped at the highestavailable rate which is between PCR and SCR. However, if thereis no available shaping rate between PCR and SCR, traffic isshaped at the next rate above the PCR.

Description AtmIf/n Uni Address/address,typeAtmIf/n Vpt/m Uni Address/address,type

This component represents an address (dynamic or static)associated with the interface. The index is a string of 1 to 40 hexdigits or a single wildcard (‘?’), and a type. The type identifieswhether the Address component is for aprimary, alternate,registered, ordefault address.

The typesprimary andalternate are used for provisionedaddresses. The typeregistered is used for dynamic addressesthrough ILMI. The typedefault is used for Soft PVP andSoftPVC addresses. Virtual interfaces do not have addresses oftypedefault.

The wildcard is only valid for provisioned addresses. If theaddress is a single wildcard, then that indicates that the interfacesupports all addresses. If there is no better match, then thisinterface may be chosen in the routing. If there is more than oneinterface with a single wildcard static address, then the choice ismade using a round robin algorithm.

The round robin algorithm first tries the primary routes. If noneof the primary routes succeed, then the alternate routes are tried.

Note that theUniInfo andPnniInfo sub-components are



mutually exclusive. Only one of these may be added under theAtmIf Uni Addr component.

This component represents an address (dynamic or static)associated with the interface. The index is a string of 1 to 40 hexdigits or a single wildcard (‘?’), and a type. The type identifieswhether the Address component is for aprimary, alternate,registered, ordefaultaddress.

The typesprimary andalternate are used for provisionedaddresses. The typeregisteredis used for dynamic addressesregistered through ILMI. The typedefault is used for Soft PVPand Soft PVC addresses.Virtual interfaces do not have addressesoftypedefault.

The wildcard is only valid for provisioned addresses. If theaddress is a single wildcard, then that indicates that the interfacesupports all addresses. If there is no better match, then thisinterface may be chosen in the routing. If there is more than oneinterface with a single wildcard static address, then the choice isdriven through a round robin algorithm.

The round robin algorithm tries the primary routes and then thealternate routes if none of the primary routes succeed.If this node participates in a PNNI hierarchy, then aPnniInfosubcomponent can be provisioned under theAtmAddress

GROUP AtmIf Vpt Vpd Provisioned (Prov)


Description This group contains the provisionable ATM Virtual PathDescriptor attributes for aVptcomponent.

ATTRIBUTE AtmIf Vpt Vpd vptType


Description This attribute specifies the type of theVpt.

On CQC-based ATM FPs allVptsmust bebasic. Vptson ATM IPFPs may be of any type.

A value ofbasicconfigures one level of traffic management (TM)for the VPT, at the VC level. VCs within the VP are treated likeindependent VCC connections, and thus, are scheduled the sameas other VCs under theAtmIf, with no scheduling done for the VPitself.

A value ofstandard configures two levels of TM for the VPT,one level for VP TM and one level for VC level TM. VCs withinthe VP use weighted fair queueing (standard VPT VCCscheduling) to schedule VCs within the VPT, with VCsdifferentiated as either real-time (CBR, rt-VBR) or non-real-time(nrt-VBR, UBR) connections. The VP itself has a full range of



emission scheduling and service category differentiation availablebetween itself and the other connections under theAtmIf.

ATTRIBUTE AtmIf Vpt CA Cbr cellLossRatio (clr)



Description This attribute specifies the tolerable cell loss ratio (CLR) for CBRtraffic. The number is the negative logarithm (base 10) of theCLR. For example, if the target CLR = 1E-10 thenCbrcellLossRatio = 10. This number must be the same as theRtVbrcellLossRatio since CBR and rt-VBR traffic have the samediscard priority. TheCbr cellLossRatiois used by the ConnectionAdmission Control (CAC) algorithm to compute the required(equivalent) cell rate for CBR connections.

There is a trade-off between the service category CLR and theachievableVpt bandwidth utilization. To guarantee an excellentservice category, the CLR should be as small as possible (e.g.,1E-10). However, a smaller CLR results in a larger equivalent cellrate for a given connection and hence a lowerVpt bandwidthutilization.

Setting this attribute to 0 means that a CLR of 1 can be tolerated.In this case, no bandwidth is reserved for CBR connections, andCAC is effectively turned off. All CBR connections are admitted.
