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
TN767E DS1 circuit pack. Bit error counting ag ainst the received test pattern
stream is terminated and send ing of the framed 3-in-24 test patter n is halted. If
either the CPE Loopback Jack or the far-end CSU is looped, the appropriate
loopback d eactivate code is sent. If the loop back 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 b y 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 TN767E circuit pack knows whic h loopback/spa n test to terminate.
All trunks or ports on the DS1 Interface c ircuit pack must be b usied 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 incorrec t
board is inserted, or an insane board is inserted.
1. Check to ensure that the board translations are correct. Use the add ds1
UUCSS command to administer the DS1 interface if it is not already
administered.
2. If board was already administered correctly, check the error log to
determine if 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, 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 link between the internal ID and the port.
