UDS1-BD (UDS1 Interface Circuit Pack)

present, administered, and connected to a 1.544 Mbps DS1 circuit pack on the
back of the port carrier.
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 ELB Test.
When the ELB Test is initiated, maintenance software sends an appropriate
message to the UDS1 Interface circuit pack to start the test. The board sets up the
ELB 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 UDS1 Interface circuit pack
are restored to the in-service state after the release board command is entered.

ABORT
CSU Equipment Loopback Test cannot be executed in the
current configuration. To run this test, the Near-End CSU Type
field on the DS1circuit pack administration form must be set to
integrated and the “Bit Rate” field on the DS1 circuit pack
administration form must be set to “1.544” (24-channel
configuration).
1. Use the change ds1 UUCSS command to set the
Near-End CSU Type field on the DS1 circuit pack
administration form to integrated, and/or change the “Bit
Rate” field to “1.544” if the board is to be used in
24-channel configuration.
2. Retry the test ds1-loop UUCSS ds1/csu-loopback-tests
command.

ABORT
Ports on the UDS1 Interface circuit pack have not been busied
out to out-of-service.
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.
