Procedure for DS1 Testing
1. Beginning with address ‘a-1-1’, place a physical DS1 loopback at ONLY this
address at the DSX-1 panel. If more than one loopback is present incorrect
wiring may not be apparent.
2. The following command and parameters test the DS1 channel’s cabling for
60 seconds.
Issue the command:
test-trmsn-t1:a-1-1
direction (mux)=demux
duration (1)=<return>
3. If transmission is not error-free, correct the problem by checking circuit
packs and associated cabling.
4. Move the physical DS1 loopback to the next DS1 channel at the DSX-1
panel; press UPD to clear the alarm caused by removing the loopback
plug. Verify that no alarms exist and continue testing the next channel.
Procedure for DS3 Testing
1. Beginning with address ‘a’, place a physical DS3 loopback at ONLY this
address at the DSX-3 panel. If more than one loopback is present incorrect
wiring may not be apparent. If DS3 cabling connects directly to DACS IV
2000 have Craft personnel put up an internal loopback or connect the DS3
‘in’ cable to the DS3 ‘out’ cable using a BNC to BNC connector.
2. The following command and parameters test the DS3 channel’s cabling for
60 seconds.
Issue the command:
test-trmsn-t3:a
direction (mux)=demux
duration (1)=<return>
3. If transmission is not error-free, correct the problem by checking circuit
packs and associated cabling.
4. Move the physical DS3 loopback to the next DS3 channel at the DSX-3
panel or place a loopback at the terminating equipment. Press UPD to
clear the alarm caused by removing the loopback plug. Verify that no
alarms exist and continue testing the next channel.
