1 FAIL Received a status of Level 1 Pending
Activation-Endpoint Idle which indicates a problem with
the BRI endpoint or ASAI or AT&T adjunct, the wiring to
the endpoint or adjunct, or the ISDN-BRI port.
For the TN2198, received a status of Level 1 Pending
Activation. U interface down, which indicates a problem
with a connection between the switch and the NT1.
NOTE:
An NT1 is a 2- to 4-wire converter that is used to
connect 4-wire AT&T terminals to a 2-wire TN2198
circuit pack. The NT1 also has status lamps to
determine the health of the unit.
1. For the TN556 or TN2208, verify that an endpoint is
connected to the port. If an endpoint is connected to
the port, then proceed to step 2. For the TN2198
verify that the connections are good between the
switch and the NT1. Verify that the NT1 has power.
2. As necessary, check and repair the wiring between
the circuit pack and the endpoint or adjunct. If a
TN2198 is used, the set must have been plugged in
for at least 15 seconds before it will stabilize.
Execute the test port PCSSpp command, and
review the results of the Level 1 Status Inquiry Test
to verify the repair. If this test is still failing, proceed
to Step 3.
3. For BRI endpoints, replace the BRI endpoint(s)
connected to the port or the NT1 if a TN2198 is
used. For ASAI or AT&T adjuncts, follow the
recommended repair procedures of the
manufacturer for link communication problems. For
the NT1, follow the manufacturers repair
procedures. Then execute the test port PCSSpp
command and review the results of the Level 1
Status Inquiry Test to verify repair. If this test is still
failing, proceed to Step 4.
4. Escalate the problem to the next tier.
