B1/B2

Enables and disables DS1 loopbacks for REMOTE/LOC
direction depending on switch setting below
REMOTE in ESF will initiate a loopback to the far-end BR1/10
side when LB is switched to ON
REMOTE in SF will initiate a loopback at the local BR1/10 side
when LB is switched to ON
LOC provides internal loopback at the T1 data stream at the
local BR1/10 side when LB is switched to ON
When set towards DS1 controls the REMOTE/LOC loopback
directions and initiates loopback with LB ON/OFF switch
When set towards DS0 controls the B1/B2 channel selection.
The TEST recessed button initiates test selected on LIU rotary
switches. This option is normally in the DS0 position once the
BR1/10 side is in service
When the switch above is in the DS0 position, B1 and B2
selects the appropriate B-Channel to be tested

Loopback Address

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

LP-SYNC* Red
ON indicates the U-interface is out of sync for the selected channel unit
LP-CRC*
Red
In normal operation flashes upon receiving NEBEs from the loop. In Local PM
mode flashes 6-19 CRCs and is solid when >20 CRC errors are detected from the
loop
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
