Table 393. TEST #886 Maintenance Looparound Test — Continued
Error Test
Code Result
NO The Packet Interface is not detected as being physically present.
BOARD
1-3 FAIL The test failed. Maintenance was unable to establish a looparound link from
the Packet Interface back to itself or was unable to receive data that was sent
out over one side of the looparound link.
PASS This test passed. The Packet Interface and its interface with the system
software are functioning properly. If the system is still unable to place calls:

Description/ Recommendation
1. Reboot the system, then retry the command. If the NO BOARD
indication persists, replace the TN2402/TN798 Processor circuit
pack.
1. Issue the test packet-interface AS command to retry the test. If the
same error code is observed, background maintenance software will
automatically attempt to reset the circuit pack and clear the problem.
2. Retry the command and if the test fails, replace the TN2402/TN798
Processor circuit pack.
3. If the test continues to fail after replacing the TN2402/TN798 Processor
circuit pack, run the test packet P long command. If any of the tests fail,
the fault may be on the Packet Bus. Refer to the PKT-BUS (Packet Bus)
Maintenance documentation for recommended repair procedures.
4. If the test continues to fail after the TN2402/TN798 Processor circuit pack
is replaced and with no other alarms associated with the Packet Bus or
circuit packs connected to the Packet Bus, follow normal escalation
procedures.
1. Check for errors on the Packet Bus and Maintenance/Test circuit
pack. Resolve those errors first.
2. Check all other circuit packs connected to the Packet Bus. Packet Bus
failures are likely to be caused by a faulty circuit pack connected to the
backplane or bent pins on the back plane.
