FE and over air gross bitrate

– Support FE up to 155 Mbps

VLAN transparent, max packet size

– VLAN packets are passed through without modification.

– Max packet size is 1536 bytes

QoS, Flow control and priority

– QoS to monitor the quality of service.

– Flow control is supported in both full-duplex and half-duplex. Full-Duplex is implemented with respect for PAUSE packets as well as generation of PAUSE packets. Half-Duplex is implemented with back-pressure.

– Priority is supported based upon Ethernet switch capabilities.

ISR IDU Standard I/O Modules: EthernetISR IDU Standard I/O Modules: Ethernet

Ingress / Egress rate setting options

– The ISR IDU slows the egress from the Ethernet switch which will initiate flow-control via the front-panel ports. The scaling of Ethernet traffic will in effect limit the front-panel egress rate on the far end of the link.

Latency

– One way latency 400 to 900 µsec at 100 Mbps (depending on packet size). Longer latency at lower data rates.

– Latency is primarily a function of

– Switch implementation

– Framing Latency

Link capacity monitoring / packet monitoring

– Link capacity is not variable, unless capacity is considered to be reduced when errored-seconds are occurring. No link capacity monitoring is available. Packet monitoring is provided in the form of Ethernet Switch Statistics (i.e. Tx Packets, Tx Bytes, Tx Errors, Rx Packets, Rx Bytes, Rx Errors).

• The ISR interleaver depth is programmable

• Evaluated latency for interleaver depths of 2, 4, 8, 16

• Various packet sizes from 64 to 1536 bytes

• Interleaver depth = 2 results in estimated performance degradation of approximately 1-2 dB– Further study may be conducted to evaluate performance

• Diversity mode: the link between each pair of modems is the same, providing complete redundancy

• This arrangement requires bandwidth for both links and non-interference between the links, but it provides hitless receive and transmit switching

• The ISR supports both frequency and space diversity

– Frequency diversity: two frequencies are used

– Space diversity: two non-interfering paths are used

• In either case, the proprietary framer chooses the best, error-free, data stream and forwards it to the Line Interface Units (LIUs)

• Does not require the extra bandwidth or interference protection of diversity mode

• Provides hitless receive switching and hot standby

• ISR IDU automatically switches transmit ODU upon appropriate ODUalarm or ODU interface error, minimizing transmit outage time

Without Spanning Tree Protocol and Ethernet loop would be

formed and packets would flood

the network.

With Spanning Tree, an artificial network break is created to

eliminate the Ethernet loop.

ISR IDU Installation OverviewISR IDU Installation Overview

• CAUTION: Do not operate units without an antenna, attenuator, or load connected to the antenna port. Damage may occur to the transmitter due to excessive reflected RF Energy.

• CAUTION: Always attenuate the signal into the receiver antenna port to less than –20 dBm. This will prevent overload and possible damage to the receiver.

• WARNING: High voltage is present inside the ODU and ISR IDU when the unit is plugged in.

• SAFETY REQUIREMENT: A switch must be employed between the ISR IDU external power supply and the ISR IDU power supplies.

ISR IDU Installation WarningsISR IDU Installation Warnings

• Back-to-back testing provides familiarity with the ISR IDU

• Required equipment

– Low-loss cables, TNC-male connectors on ODU interfaces

– Inline RF attenuators rated for ODU frequency,

• Four 40 dB or two 40dB and one 80 dB

• IDU and ODUs must be in an operational configuration

ISR IDU Installation and EvaluationISR IDU Installation and Evaluation

• The received signal level (RSL) can be estimated using the following:

RSL (dBm) = PTX + GTX ANT – LPath + GRX ANT

PTX = transmitter output power (dBm)

GTX ANT = transmit antenna gain (dB)

GRX ANT = receive antenna gain (dB)

LPath = path loss (dB)

LPath = 36.6 + 20 log10 (F*D)

F = frequency (MHz)

D = path distance (miles)

• The expected RSL and measured RSL should be close (± 5 - 10 dB)

ISR RSL and Link BudgetISR RSL and Link Budget

• The fade margin is the difference between the actual

received signal and the ISR’s threshold, for the modulation

mode selected

• Used to determine availability

• Should be at least 10 dB

ISR Fade Margin CalculationISR Fade Margin Calculation

• Availability of the microwave path predicts the percent of time that the link will operate without producing an excessive BER due to multipath fading

• Vigants Barnett Method

Availability = 100 x (1 – P)

P = 2.5 x 10-9 x C x F x D3 x 10(-FM/10)

F = Frequency (MHz)

D = Distance (miles)

FM = Fade Margin (dB)

C = Climate/ Terrain Factor =

4 for Humid/ Over Water (worst case)1 for Average Conditions0.25 for Dry/ Mountains (best case)

ISR Availability CalculationISR Availability Calculation

• Location should:

– Have easy access to power supply and other equipment in network (i.e. a router or PC)

Grounding the ISR IDU

– Connect the system or building ground

point:

• Rack ground

• Power third-wire ground

– Cable should be ≤ 36 inches

– Connect to either ground on front panel

• Use 6-32 x 5/16 maximum length

screws to fasten

ISR IDU: GroundingISR IDU: Grounding

1. Connect ISR power cable to a –48 Vdc supply

• Connect a voltmeter to the unconnected IDU cable end– Positive probe to pin 2 (-V)

– Negative probe to pin 1 (RET)

• Verify that: –44 Vdc ≥ voltmeter reading ≥ -52 Vdc

2. Turn the –48 Vdc supply off

3. Plug the ISR IDU power cable into the ISR IDU

• Place the voltmeter probes on the cable connector terminal screw heads

4. Turn the –48 Vdc power supply on

• Verify that: –44 Vdc ≥ voltmeter reading ≥ -52 Vdc

5. Connect the ISR to a PC

• Use a Cat-5 Ethernet Cable

• Connect directly to a PC or to a computer network

• Connect the NMS 1 or NMS 2 connector

• Check the connection by performing a “ping” command
