End Loopback/Span Test (#1216)
This test is destructive.
The End Loopback/Span Test will terminate an active loopback or span test on a
TN464F 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 could not be deactivated, then
the test will FAIL and a MINOR alarm will be 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 Since only one of these three different long-duration loopback/span
tests can be active at a time, the TN464F circuit pack knows which
loopback/span test to terminate.
All trunks or ports on the UDS1 Interface circuit pack must be busied out via the
system technician busyout board command before running this End
Loopback/Span Test.
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
PCSS 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.
