3. Replace the PN’s Maintenance circuit pack, and run the test again. If the
test passes, the problem is with the Maintenance circuit pack. Interchange
the PNC by entering the reset pnc interchange command, and run the test
again. The test should pass with both EI circuit packs being active.
4. If the B carrier EI circuit pack is active, the ribbon cable connecting the
Expansion Interface circuit pack and the PN’s Maintenance circuit pack may
be defective. Check the ribbon cable to make sure it is connected properly
and is not damaged.
For unduplicated Port Network Connectivity:
1. Replace the PN’s Maintenance circuit pack, and run the test again. If it
passes, the problem is with the Maintenance circuit pack.
2. If the test fails, replace the EI circuit pack. If the tests passes, the problem is
with the EI circuit pack.
3. If the test still fails, the problem is with the serial link wired into the
backplane of carrier A.

FAIL
PN Maintenance Circuit Pack reset passed, but the PN’s Maintenance circuit
pack did not respond to subsequent handshake message. Retry this command
three more times. If it continues to fail, the Maintenance circuit pack, the active
EI circuit pack, or the serial link is defective. To determine which is defective,
follow the appropriate procedures that follow.
Duplicated Port Network Connectivity:
1. Interchange PNCs by entering reset pnc interchange.
2. Run the short test sequence against the PN’s Maintenance circuit pack. If
Test #306 still fails, replace the Maintenance circuit pack and retest.
Otherwise, follow the error routines for any errors that are logged by this
short test sequence.
Unduplicated Port Network Connectivity:
1. Replace the PN’s Maintenance circuit pack, and invoke the short test
sequence against it.
2. If the error persists, replace the EI circuit pack, at a time when the PN can
go down with minimal inconvenience.
3. If the error still persists, the problem is with the actual serial link in A carrier
backplane and not with the PN’s Maintenance circuit pack.
PASS
The active EI circuit pack can reset the PN’s Maintenance circuit pack. This
implies the Maintenance circuit pack, the active EI circuit pack, and active serial
link are sane. There could still be a problem with the standby EI circuit pack and
standby serial link in a Duplication Option system.
