BCU MANUAL TESTING DIP SWITCHES

LB ON/OFF Enables and disables DS1 loopbacks for REMOTE/LOC

direction depending on switch setting below

REMOTE/LOC 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

DS0/DS1 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

B1/B2 When the switch above is in the DS0 position, B1 and B2

selects the appropriate B-Channel to be tested

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
