TDM Loop Around Test (#183)
This test is destructive.
This test requires that you enter the busyout link lnk-no command before
running the test. This means that the DCS, AUDIX, or ISDN link, for example, are
torn down. This test checks the health of the TN754 or TN784 DIG-LINE or the
TN722 or TN767 DS1 Interface circuit pack. This depends on which circuit pack
is used on the link. The TN754 or TN784 Digital Line or DS1 Interface circuit pack
is put into loop around mode while the PI-BD is instructed to go into remote loop
around. If this test fails, and the previous Test #182 passes, then the TN754 or
TN784 Digital Line or the DS1 Interface circuit pack should be replaced. It is not
run on ports administered as EIA.

ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
6 ABORT The system could not allocate time slots for the test. The system may be under
heavy traffic conditions or it may have time slots out-of-service due to
TDM-BUS errors. Refer to “TDM-BUS” to diagnose TDM-BUS errors.
1. If system has no TDM-BUS errors and is not handling heavy traffic, repeat
test at 1-minute intervals a maximum of 5 times.
9 ABORT TN754 or TN784 Digital Line or TN722 or TN767 DS1 Interface circuit pack is
not installed.
1. Install circuit pack and retry the test.
13 ABORT The TN765 circuit pack has not been reset yet or is currently being reset.
1. Retry the command at 1-minute intervals a maximum of 5 times.
2. If test continues to abort with error code 13, then check status of all BX.25
and/or ISDN-PRI links on this TN765 via the status link lnk-no command.
If all links are not in-service, then reset the TN765 using the test interface
PCS long command.
3. If the TN765 fails to reset, refer to the PI-SCI section of this manual.
4. Else, retry the test link lnk-no command.
5. If the test still aborts with error code 13 or from step 2, and some links are
in-service and a error code is still present, escalate the problem.
