UDS1-BD (UDS1 Interface Circuit Pack)
DS1 Board Loopback Test (#1209)
This test is destructive.
The DS1 Board Loopback (BLB) Test causes a loopback at the DS1 board edge
and tests DS1 board internal circuitry.
The test is destructive and can only be initiated by a system technician demanded
test ds1-loop UUCSS ds1/csu-loopback-tests command.
All trunks or ports on the UDS1 Interface circuit pack must be busied out using the
system technician busyout board command before running the BLB Test.
When the BLB Test is initiated, maintenance software sends an appropriate
message to the UDS1 Interface circuit pack to start the test. 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 pattern is
different, the test fails.
When the test is complete, all trunks or ports on the TN464GP/TN2464BPTN
UDS1 Interface circuit pack are restored to the in-service state after the release
board command is entered.

Code Result
ABORT Internal system error
1005 ABORT DS1 Board Loopback Test cannot be executed in the current configuration. To
run this, the TN464F or later suffix UDS1 must be administered for 24-channel
operation. The "Bit Rate" field on the DS1 circuit pack administration form
must be set to "1.544" for 24-channel operation.
1015 ABORT Ports on the UDS1 Interface circuit pack have not been busied out to
out-of-service.

Description/ Recommendation
1. Retry the test ds1-loop UUCSS ds1/csu-loopback-tests command at
1-minute intervals a maximum of 5 times.
1. Enter the busyout board UUCSS command to put all trunks or ports of
the UDS1 Interface circuit pack into the out-of-service state.
2. Retry the command.
