End Loopback/Span Test (#1216)
This test is destructive.
The End Loopback/Span Test will termin a t e an active loo pback or span test on a
TN464F UDS1 circuit pack. Bit error counting against the received test p attern
stream is terminated and send ing of the framed 3-in-24 test p attern is halted. If
either the CPE Loopback Jack or the far-end CSU is looped, the approp riate
loopback d eactivate code is sent. If the loopback c ould not be deac tivated, 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
test ds1-loop UUCSS end-loopb ack/span-test
command. Since only
one of these three different long-duration loop back/span tests c an be active at a
time, the TN464F circuit pack knows whic h loopback/sp an test to terminate.
All trunks or ports on the UDS1 Interface c ircuit pack must b e busied out via 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 admini ster the UDS1 interface if it is not alread y 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 b oard 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.
