Ethernet Interface Setting

The Ethernet interface for the connection must be selected. There are three options:• If the PseudoWire traffic is delivered to the BTS site via 100 Base-T Ethernet, you need to

configure the PseudoWire mode with the EIF1 or EIF2 interface selected.

• If the PseudoWire traffic is delivered to the BTS site via optical Gigabit Ethernet, you needto configure the PseudoWire mode with the EIF3 interface selected. Auto negotiation isnot applicable for EIF3. Note that this option can only be selected if a compatible SFPmodule is inserted into the FIQA or FIYA.

• If you select none, you can continue with the PseudoWire configuration but no Ethernetinterface is taken into use. PseudoWire operation is not possible in this case.

• Note that the Ethernet switching feature is supported as soon as more than one Ethernet

interface is taken into use. In case of Fast Ethernet, the default speed is 100 Mbps. If Auto

negotiation is disabled, the fixed 100 Mbps speed is in use. If Auto negotiation is enabled,

the interface uses the negotiated speed. In case of Gigabit Ethernet, the fixed speed is1Gbps.

• Auto negotiation is not supported. Manual configuration of speed or duplexity is notsupported for any of the Ethernet interfaces.

• The Interface role settings can also be specified. When defining the role for the three

Ethernet interfaces, backhaul port is mandatory and should be assigned to only one in use

interface. The default role is Access_Switched. A port which is already assigned with

Backhaul role cannot have any other role. Ingress policing is mandatory only if the role

given to a port is 'Access QoS IPSec scheduled'. For all the other roles this field is

disabled




RA22754EN03GLA0 90

Packet Abis Transport

This screen allows you to configure packet and traffic related parameters in packet Abis andPacket Abis Relay modes for a packet switched network. In the Packet Configuration tab,the MTU is not a mandatory field. The DSCP parameters are displayed when the 2G FlexiBTS Site manager is in online mode only.




RA22754EN03GLA0 91


In the Shaping and Scheduling tab, the Committed information rate field is enabledonly if traffic shaping is enabled. If traffic shaping is enabled, the Committed information rateis a mandatory field.

Traffic shaping is used for the network or traffic sources to control traffic entering thenetwork, and to limit the allowed egress rate over the Abis interface.

The Committed information rate is the average rate up to which packets or frames aredelivered by the network.




RA22754EN03GLA0 92

Network Plane Settings

All the fields in this screen are mandatory.When Packet Abis is used, it is mandatory to have supervision for the user plane. The BTSsends dummy packets in periodic intervals to the BSC.

The BSC filters these packets based on the UDP Radio Channel port (indicating a non-validTRX) and forwards them back to the BTS. BTS starts sending dummy packets when there isat least one functioning TRX, and stops sending the packets when there are no functioningTRXs (no TRX signaling link). You can specify the time interval for the BTS to send thepackets for data and voice under User plane supervision.

The BTS IP address is the M-plane IP address, and the BSC IP address is the BSC MplaneIP address for that BTS. The subnet mask is the BTS M-plane subnet mask. The gateway IPaddresses are of the local subnet that the BTS belongs to.

In PAoPSN Relay Mode, when the system is uncommissioned (with bypass capacity) and

commissioned again, then the BSC IP address parameter must be configured again.




RA22754EN03GLA0 93

Ethernet Operation and Maintenance Support

This feature is used to monitor the performance of the network.You can specify the Maintenance Entity Group (MEG) and Maintenance Entity Point (MEP)parameters using this screen.

Each MEG can have a maximum of two MEPs.




RA22754EN03GLA0 94

This screen allows you to configure the SCTP and IU A parameters. By default, thetransmission medium selected is 'Fast' and all the fields that depend on the transmissionmedium are provided with the default value corresponding to that medium.

If you try to change any of the default values, the transmission medium automaticallychanges to ‘User defined’.

The supported transmission mediums are 'Fast', 'Medium', 'Satellite' and 'User defined'.

When there is a fast connection to the BSC, ‘Fast’ is selected as the transmission medium.

This facilitates faster retransmission and earlier error detection, whereas, when thetransmission time is longer, leading to longer error detection times, “Satellite’ is selected asthe transmission medium.

The Minimum SCTP port must match the OMU SCTP port at the BSC.




RA22754EN03GLA0 95

Packet Abis Security

Packet Abis security feature is available only with FIYx/FIQx PIUs operating in Packet Abisor Packet Abis Relay online mode for a packet switched network.

This is a licensed feature.

Global IP Security is enabled when you want secured traffic to be sent/received for any ofthe planes.

This option can also be used to fetch certificates from the certification authority orcertification repository.

In this case, Certificate Management Protocol also needs to be enabled.

In the IPSec tab, specify the security and encryption parameters.




RA22754EN03GLA0 96


In the Transmission Plane tab, the tunnel settings for planes can be specified.The tunnel IPs become mandatory when the 'Global IP security' is 'On' and the 'IPSec‘ forthe corresponding plane is either 'On' or 'Probe'.

By default, it is mandatory to fill the values for first tunnel Id in the tunnel settings table.

If there is already a tunnel configured in the tunnel settings table or you start configuring thesecond tunnel, then the mandatory indication in the first row disappears.




RA22754EN03GLA0 97


In the Firewall tab, you can specify the firewall settings. Select the Enable ICMPredirect option if IP routing is used between the source and destination, that is, if anIP gateway is configured.

With ICMP redirect message, the gateway may update the routing to a dedicated destinationby providing a new gateway address. So, when the BTS receives an ICMP redirectmessage from the gateway, it updates the routing table for the destination of the packet thattriggered the ICMP redirect message.

However, this routing update is not permanent, that is, the configured gateway address isnot changed and becomes effective again after a reset. The purpose of this feature is tooptimize routing to the destination.

Select the Enable packet filtering option to activate the BTS firewall.

This feature should always be enabled.

Synchronization

On the Sources tab, you can:• Configure the clock priority list from a list of available clock sources. You can only selectone of the PseudoWire interfaces as a synchronization source.

• Add or remove sources from the priority list.

• Increase or decrease the priority of a source in the list.

Note that if Internal Timing is part of the priority list, it has always the lowest priority.

When the FIYB/FIQB plug-in units are used, there are some additional synchronizationsources available. The synchronization sources specific to FIYB/FIQB are Timing overPacket (ToP) and Synchronous Ethernet (SyncE). ToP and SyncE have separate licenses.

Only one among ToP, SyncE, and PseudoWires can be moved into the priority list at a time.

ToP master IP address parameter becomes mandatory when ToP is moved into the prioritylist. When ToP or SyncE are moved to the Priority List, the 'Optional Parameters' button isdisplayed. The optional parameters of ToP and SyncE can be configured through thewindow which appears on clicking the 'Optional Parameters’ button.

The ToP parameters define the synchronization message rate and time interval formeasuring the rate. In the ‘Announce message rate’ field, specify the interval of receivingannounce messages by ToP Slave clock from ToP master. The ‘Unicast transmissionduration’ specifies the duration for which the TRS receives sync messages from the ToPmaster.

You can enable Synchronization status messages (SSM). The SSM message includes thequality level of incoming reference signals. This enhances reliability across the network forthe operator and eases troubleshooting.

This screen enables you to configure the Packet Abis transport parameters. You can viewthe DSCP parameters when the 2G Flexi BTS Site Manager is in online mode only.

Click on the ML/MC-PPP Class Mapping button to view the DSCP and ML/MC-PPPClass mapping. The ML/MC-PPP Class Mapping and the scheduling weights are defined inthe BSC, and can only be viewed in the 2G Flexi BTS Site Manager.

If header compression of ML- PPP and UDP/IP headers are enabled, IP headercompression is the process of compressing excess protocol headers before transmittingthem on a link and uncompressing them to their original state on reception at the other endof the link. It is possible to compress the protocol headers due to the redundancy in headerfields of the same packet as well as consecutive packets of the same packet stream.

Since header compression may not be available in all network elements, this functionality isoptional and to be enabled/disabled by configuration. The header compression settingsmust be in line with those at the BSC.




RA22754EN03GLA0 113

Network Plane Setting

All the fields in this screen are mandatory.When Packet Abis is used, it is mandatory to have supervision for the user plane. The BTSsends dummy packets in periodic intervals to the BSC. The BSC filters these packets basedon the UDP Radio Channel port (indicating a non-valid TRX) and forwards them back to theBTS. BTS starts sending dummy packets when there is at least one functioning TRX, andstops sending the packets when there are no functioning TRXs (no TRX signaling link).

You can specify the time interval for the BTS to send the packets for data and voice underUser plane supervision.

The BTS IP address is the M-plane IP address, and the BSC IP address is the BSC MplaneIP address for that BTS. The subnet mask is the BTS M-plane subnet mask.




RA22754EN03GLA0 114

Protocol Settings

This screen allows you to configure the SCTP and IUA parameters.By default, the transmission medium selected is 'Fast' and all the fields that depend on thetransmission medium are provided with the default value corresponding to that medium. Ifyou try to change any of the default values, the transmission medium automatically changesto ‘User defined’. The supported transmission mediums are 'Fast', 'Medium', 'Satellite' and'User defined'.

When there is a fast connection to the BSC, ‘Fast’ is selected as the transmission medium.This facilitates faster retransmission and earlier error detection, whereas, when thetransmission time is longer, leading to longer error detection times, “Satellite’ is selected asthe transmission medium. The Minimum SCTP port must match the one at the BSC.




RA22754EN03GLA0 115

PPP Configuration

You can select between the MC4, MC2, ML, and PPP modes.When the mode selected is PPP, only one channel can be configured for each bundle in thePPP bundle allocation screen if the mode is changed from a non-PPP mode to PPP whenmore than one channel misconfigured for each bundle, the following error is displayed




RA22754EN03GLA0 116

Define the PPP bundles.

This page allows you to allocate bundles for the chosen E1/T1 interface. A bundle is acollection of timeslots of one or multiple E1/T1 interfaces.

The minimum required bundle size is 128kbps.

The same bundle can span across different interfaces. Each bundle has a bundle id. Achunk of continuous timeslots of a bundle is called a channel. A bundle can have maximumup to 8 channels. Maximum number of channels possible for all the bundles is 68.Configuration of bundle 1 is mandatory as it is used for routing the backhaul traffic to BSC.For bundle 1 no other routing is possible.




RA22754EN03GLA0 117

PPP bundle protection values

In this screen, you can define protection of one interface with another interface, that is if oneinterface goes down, the protecting interface becomes active for transmission.




RA22754EN03GLA0 118

Routing configuration between different PPP bundles

You can enable/disable the IP routing state using the IP routing enabled checkbox.

You can also add new routes and configure up to 128 routing entries irrespective of the IProuting state. You can add or delete the routing entries.

Route to the IPCP peer IP addresses of a bundle is implicitly learned to go via that bundleas soon as the bundle comes up. Removal of any routing information from routing table bythe operator has no impact on these implicitly learned routes. The IP Routing screen doesnot display these implicit routes.




RA22754EN03GLA0 119

Synchronization Parameters

Synchronization parameters.

On the Protection tab, you can define the synchronization/Q1 Loop protection.

If synchronization/Q1 Loop protection is not configured, then the topology is shown as'Chain'. If 'Loop' topology is selected to configure synchronization/Q1 Loop protection, it ismandatory to configure Master Clock Bit/Loop Control Bit (MCB/LCB). You need to specifythe position of MCB/LCB bits on a Priority 1/Primary Interface and a Priority 2/SecondaryInterface.

PDH Loop Protection is a function that provides instant recovery from transmission failuresin a network of network elements, where each element is assigned two independenttransmission routes. In the case of a fault in one route, traffic, synchronization and Q1management functions are switched by the system automatically to the intact route.

Q1 Management

Click Add, select the sampling rate (will be the same for all Q1 EOC allocations), and definethe other settings in the table to meet user requirements. If user enable the Q1 loopprotection, select the Loop option (primary and secondary) in the table.

Note :

For Q1 polling to work properly over time-slot 0, the base transceiver station (BTS) has to becommissioned with the OMUSIG or cross-connected traffic.

Q1 EOC Allocation Q1 EOC channels are used to carry Q1 commands from the Q1 entities- Master/Slave over the interfaces. User can add and delete the Q1 EOC channels. Onlyone EOC channel can be made for each Interface.

Q1 Polling Mode is displayed in the online mode. The values can be BTS Polling or BSCPolling.

In BTS polling, Flexi MultiRadio BTS supervises (is Q1 master) all internal or externaltransmission equipment connected to the BTS.

In BSC polling, the BSC supervises all transmission equipment (is Q1 master). The externalequipment can be connected to the BTS through Q1 cable or via configured Q1 EOCchannel. The polling mode cannot be changed manually at the BTS but is the result of theconfiguration at the BSC.

In the Flexi MultiRadio BTS it is not necessary to manually configure any Q1 switches toestablish the internal Q1 paths. The configuration is done automatically based on the Q1polling mode. As a consequence all internal or external transmission devices connected tothe BTS must be either BTS polled or BSC polled. A combination of polling modes is notpossible. This must be observed particularly when configuring the external devices(connected either through Q1 cable or EOC channel).

When the FIYB/FIQB plug-in units are used, there are some additional synchronization

sources available. The synchronization sources specific to FIYB/FIQB are Timing over

Packet (ToP) and Synchronous Ethernet (SyncE). ToP and SyncE have separate licenses.

Only one among ToP, SyncE, and PseudoWires can be moved into the priority list at a time.ToP master IP address parameter becomes mandatory when ToP is moved into the priority

list. When ToP or SyncE are moved to the Priority List, the 'Optional Parameters' button is

displayed. The optional parameters of ToP and SyncE can be configured through the

window which appears on clicking the 'Optional Parameters’ button.

The ToP parameters define the synchronization message rate and time interval for

measuring the rate. In the ‘Announce message rate’ field, specify the interval of receiving

announce messages by ToP Slave clock from ToP master. The ‘Unicast transmission

duration’ specifies the duration for which the TRS receives sync messages from the ToP

master. The ‘Unicast transmission duration’ specifies the duration for which the TRS
