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

Indicator Color Description

AY Amber ON indicates a Yellow Alarm is being received from the T1 carrier facility AR Red ON indicates the BR1/10 side is in a Red Alarm condition TP Amber ON indicates Trunk Processing is active on all U-BRITEs (10) RCV Red ON indicates a loss of framing of T1 signal from the T1 carrier facility ESF Green ON indicates the T1 Extended SuperFrame format is selected SF Green ON indicates the T1 SuperFrame format is selected B8ZS Green ON indicates T1 B8ZS line coding is selected AMI Green ON indicates T1 AMI line coding is selected 10DSL Green ON indicates D Channel 4:1 TDM mode is selected to transport 10 BRIs 8DSL Green ON indicates TR-397 3-DS0 framing across the T1 facility to transport 8 BRIs EXT Green ON indicates External timing input is selected (BITS) LOC Green ON indicates BR1/10 side is using a locally generated clock source to time the

T1 network LOOP Green ON indicates BR1/10 clock is recovered clock from the T1 network CAU Green ON indicates clock is recovered from the DSL position #1 to time the T1 network DS1-LOC Green ON indicates the BR1/10 side is in a Local DS1 Loopback RMT Green ON indicates the unit has initiated remote DS1 loopback when set in ESF mode

FLASHING indicates it responded to remotely commanded loopback, or has

provided a loopback path for the T1 data-stream in SF mode 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 BR1/10 side

BR1/10 2X MINI ISDN CHANNEL BANK

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
