It can be use for installation, serve, andmaintenance of 2Mbps transmission paths which contain voice, data service at 2.048 Mbps rate.The test set is connected to the primary data transfer interface (ITU-T Recommendation G.703). It can be operate as agenerator/supervisor for different types of test signal in AMI and HDB-3 coding or as a monitor/signal analyzer for PCM systems(ITU-T Recommendation 0.162)Technical specificationsOutput Line interfaceInterfaceConnectorG.703RJ-45, banana or BNCTX50E e-Manual D07-00-009 Rev A01Page 4 of 28RateImpedancePulse masksLine codeMaximum peak to peakjitter2.048 Mbit/s120 O balance or 75 O unbalanceG.703AMI, HDB-30.015 UIpp (Conforms to G.823)Input Line interfaceInterfaceConnectorRateImpedancePulse masksLine codeMaximum input jitterG.703RJ-45, banana or BNC2.048 Mbit/s120 O balance or 75 O unbalanceG.703AMI, HDB-3Conforms to G.823TransmitterTransmitter ClockClock sourceFrom received signalInternal: 2.048 Mbps ± 3ppmExternal: 2.408 MHz or 2,048 MbpsInternal clock stabilityFrequency offset5 ppm± 6 KHz in 1 Hz resolutionFrame structure2048 kbit/s G704PCM 30, PCM31 with/without CRC-4Test PatternPattern typesFixed: All 1, All 0, 1010PRBS: 2n-1 where n = 6, 9, 11, 15, 23Pattern StandardO.153O.152, O.153O.151O.151O.151TX50E e-Manual D07-00-009 Rev A01Page 5 of 28Fixed word lengthPolarity24 bitNormal, invertedAlarm and ErrorsGeneration modesErrors/Slips insertionErrors rateAlarm typeSingle, continuous, user definedContinuous or single1 x 10-n, where n= 2 to 7LOS - Loss of SignalAIS - Alarm indication signalLOF - Loss of Frame alignmentRDI - Remote Alarm IndicatorLOM - Loss of CAS Multiframe AlignmentRMA - Multiframe Remote Alarm IndicatorLSS - Loss of Test Sequence SynchronizationARTF: Unstructured alternating 1s and 0s.Error typeCODE - Code errorFAS - Frame alignment errorCRC - CRC-4 block errorREBE - CRC block error in remote endBIT - Bit error in PRBS and fixed word+SLP - Positive bit slip-SLP - Negative bit slipE-bit - Transmitted E-bit errorsMFAS - Multiframe Alignment SynchronizationReceiverReceiver ClockClock sourceRecovered form received data streamFrame structure2048 kbit/s G704PCM 30, PCM31 with/without CRC-4Test PatternPattern typesFixed: All 1, All 0, 1010PRBS: 2n-1 where n = 6, 9, 11, 15, 23Pattern StandardO.153 [ Pobierz całość w formacie PDF ]
