Maintenance Looparound Test (#886)
This test checks whether the Packet Interface circuit pack can send and receive
data correctly. It establishes a LAPD link from a Packet Interface circuit pack
back to the same Packet Interface circuit pack and transmits and receives test
data over that testing link. While timing signals from the Packet Bus are used for
the data transfer, the data itself is looped around on the circuit pack at the
interface to the Packet Bus and does not get sent over the Packet Bus.
NOTE:
This test is not run if the Packet Interface circuit pack is on a standby SPE in
a system equipped with duplicated SPEs. However, a failure of the
Maintenance Looparound test may have caused an SPE interchange which
would result in an alarm associated with the looparound failure error code
769 being reported against a Packet Interface circuit pack that is currently
on the standby SPE. If that is the case, and if all other Packet Interface tests
associated with the
test packet-interface CS long
pass, force the standby
SPE to go active by using the SPE-SELECT switches. Then enter the
test
packet-interface CS
command to run the Maintenance Looparound test to
make sure the problem has been cleared.

ABORT Packet Interface circuit pack is in the out-of-service state so normal
maintenance tests will not run on that circuit pack.
1. Request a Packet Interface circuit pack reset using the reset
packet-interface CS command. Refer to the Packet Interface Reset Test
(#889) maintenance documentation for further action.
1139 ABORT The Packet Bus is alarmed
1. Try to retire the alarm associated with the Packet Bus. Refer to the Alarm
Log via the display alarms command. Refer to the maintenance
documentation for Packet Bus Maintenance for further action.
2. Retry the command when the alarm associated with the Packet Bus is
retired.
1335 ABORT Internal system error. The Packet Interface circuit pack is on the standby SPE
and this test is not allowed to execute on a Packet Interface circuit pack on the
standby SPE.
1. If you wish to run this test on the standby Packet Interface, you must first
make it active with reset system interchange. Be sure you understand
the implications explained in
Planned SPE Interchange
in Chapter 5,
‘‘Alarms, Errors, and Troubleshooting’’.
