LOOPBACK TEST (ADR6, NT1)

Loopbacks in the network to customer direction can be initiated from either the ISDN switch (eoc) or the BR1/10 LIU and BCU. The down-stream direction is automatically selected based on the channel unit position in the circuit. To initiate a loopback, perform the following steps:

1. Insert TX and RX bantam plugs of the DS0 digital test set (i.e. TPI 108/109) to the TEST jacks of the

LIU

2. Connect test set clock interface to DB9 connector of the LIU and configure the test set for Near Logic and 64kb/s

3. Select the desired U-BRITE using the DSL rotary switch on the LIU( the selected U-BRITE LED flashes red and green for 3 seconds

4. Select the desired loopback address using the address rotary switch on the LIU (note: ADR1 is always the U-BRITE your test set is connected to

5. Select DS0 option and select the desired Bearer channel B1/B2 dip switches on the BCU

6. Press the recessed TEST push-button on the BCU to initiate the loopback test

7. The DS0 LB status LED on the BCU will illuminate if the loopback is successful and will not illuminate if the loopback failed

8. Send and Receive 2047 to the established loopback and observe the DS0 digital test set for bit errors

9. It is not necessary to exit the test mode to select additional addresses (ADR2, NT1) or to change to B1/B2 channels

10. To terminate the loopback, press the TEST push-button and the amber DS0-LB LED will go out

CR-SYNC*

Red

ON indicates no TR-397 framing across the T1 carrier for the selected channel

CR-CRC*

Red

In normal operation flashes upon receiving NEBEs from the T1 carrier. In Local

 

 

PM mode flashes 6-19 CRCs and is solid when >20 CRC errors are detected

 

 

from the T1

DS0-LB*

Amber

ON indicates the selected U-BRITE is in a 2B+D commanded eoc loopback.

 

 

Flashing once per second=B1 is looped, flashing twice per second=B2 is looped

ACT*

Green

ON indicates the customer’s NT1 has successfully exchanged ACT bits with the

 

 

network for the selected channel

*Status is for the channel unit selected on the DSL 10-position rotary switch on the LIU of the the BR1/10 side
