LCT CONNECTION (1) The Pasolink equipment can be configured controlled

and monitored locally using the Local Craft Terminal(LCT). Using the LCT it is possible to monitor the localIndoor Unit and related Out Door Unit

A personal computer can be used as the LCT andterminal software like windows Hyper terminal can beused to communicate with the IDU.

The terminal software, communications parametersshould be set as follows

LCT CONNECTION (2) The Remote Pasolink equipment (opposite station ) can

be configured controlled and monitored from the localIDU using the Local Craft Terminal (LCT). Connect theLCT to the NMS/RA port. Using the LCT it is possible tomonitor the Remote Indoor Unit and related Out DoorUnit

Remote configuring/monitoring is not possiblewhen the PM card is mounted or during HBER alarmcondition.

FRAME IDSelect item No.This item

defines the Frame ID ofthe transmit/receive signal.The Frame ID is used atthe receive station toidentify the correct receivesignal.

As a signal with a differentFrame ID cannot bereceived, the Frame ID ofthe opposite stationshould be set to the sameID number.

BER ALARM THRESHOLDWhen excessive BER is

detected, the IDU insertAIS into the data streamssent to the MUXequipment. Thresholdvalue for AIS insertion canbe selected as 1 x 10-3, 1x 10-4, 1 x 10-5 or 1 x10-6.

In the (1+1) Hot standby system, both No.1 and No.2channels should have the same Frame ID. Thenumber of Frame IDs, which can be set, is eight (ID0to ID7).
