End Loopback/Span Test (#1216)
This test is destructive.
The End Loopback/Span test terminates an active loopback or span test on a
UDS1 circuit pack. Bit error counting against the received test pattern stream is
terminated and sending of the framed 3-in-24 test pattern is halted. If either the
CPE Loop-Back Jack or the far-end CSU is looped, the appropriate loopback
deactivate code is sent. If the loopback cannot be deactivated, then the test
returns FAIL, and a MINOR alarm is noted in the alarm log until the loopback is
cleared.
The test is highly destructive and can only be initiated by a technician-demanded
test ds1-loop UUCSS end-loopback/span-test command. Since only one of
these three different long-duration loopback/span tests can be active at a time, the
UDS1-BD circuit pack knows which loopback/span test to terminate.
Every trunk or port on the UDS1 Interface circuit pack must be busied out using
the system technician busyout board command before running this End
Loopback/Span test.
The list measurements ds1 summary command will display the length of time
the test ran (Test Duration field) and number of bit errors detected
(Loopback/Span Test Bit-Error Count field).
To restore the trunks or ports on the UDS1 Interface circuit pack to the in-service
state, execute the release board command.

Result Description / Recommendation
ABORT Internal system error
1. Retry the test ds1-loop UUCSS end-loopback/span-test command at
1-minute intervals up to 5 times.
1005 ABORT End Loopback/Span test cannot be executed in the current configuration. To
run this test, the TN464F or later suffix DS1 board 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.
1. Enter the busyout board UUCSS command to put every trunk or port of
the UDS1 Interface circuit pack into the out-of-service state.
2. Retry the command.
