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 Loopback 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 system 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.
All trunks or ports on the UDS1 Interface circuit pack must be busied out using the
system technician busyout board command before running this End
Loopback/Span Test.
PASS A single bit error has been successfully injected into an active
framed 3-in-24 test pattern.
0NO
BOARD
The test could not relate the internal ID to the port (no board).
This could be due to incorrect translations, no board is inserted,
an incorrect board is inserted, or an insane board is inserted.
1. Ensure that the board translations are correct. Execute the
add ds1 UUCSS command to administer the UDS1
interface if it is not already administered.
2. If the board was already administered correctly, check the
error log to determine whether the board is hyperactive. If
this is the case, the board is shut down. Reseating the board
will re-initialize the board.
3. If the board was found to be correctly inserted in step 1, then
issue the busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the linkage between the internal ID and
the port.
