Maintenance Demand Tests
When the BLB test is initiated, maintenance software sends a message to the DS1 Interface
circuit pack. The board sets up the BLB loopback, transmits a test pattern, and verifies that the
pattern is received unaltered through the loopback. If the transmitted and received patterns are
different, the test fails.
When the test is complete, enter release board to restore all trunks or ports on the DS1
Interface circuit pack to the in-service state.
This test is run on the following maintenance objects:
● DS1-BD (DS1 Interface Circuit Pack)
● MG-DS1 (DS1 Interface Media Module)
● UDS1-BD (UDS1 Interface Circuit Pack)

Description / Recommendation
ABORT Internal system error
1. Retry test ds1-loop location ds1/csu-loopback-tests
at 1-minute intervals up to 5 times.
1005 ABORT The DS1 Board Loopback test cot be executed in the current configuration.
To run this test, the DS1 must be administered for 24-chel operation. The
Bit Rate field on the DS1 circuit pack administration screen must be set
to “1.544” for 24-chel operation.
1015 ABORT Ports on the DS1 Interface circuit pack have not been busied out.
1. Enter busyout board location to put all trunks or ports of the
DS1 Interface circuit pack into the out-of-service state.
2. Retry the command.
1039 ABORT The DS1 Interface circuit pack is providing timing for the system. Executing
this test could cause major system disruption.
If the DS1 Interface circuit pack needs to be tested, set the
synchronization reference to another DS1 Interface circuit pack or to the
IPSI or Tone-Clock circuit pack using the following command sequence:
1. disable synchronization-switch
2. set synchronization location
3. enable synchronization-switch
1412 ABORT This test does not run on media modules or media gateways. Ignore.
