Test
Result
8 FAIL ATM-SGRP: There is a problem with the ATM TN230X circuit pack or
the ATM signaling chel (D-chel), preventing any ISDN trunk calls until
the problem is resolved.
1. Consult the procedures for the TN230X ATM-TRK (Circuit
Emulation Service Circuit Pack) and the ATM-DCH (ATM D-Chel
Port).
ISDN-SGR: There is a problem with the UDS1 TN464 UDS1 circuit pack
or the DS1 Interface Media Module or the ISDN-PRI Signaling Chel
(D-chel). No ISDN trunk or PRI endpoint calls can be made until the
problem is resolved.
1. Consult the procedures for the UDS1-BD (UDS1 Interface Circuit
Pack) or the MG-DS1 (DS1 Interface Media Module), and the
ISDN-PLK (ISDN-PRI Signaling Link Port).
0 NO
BOARD
Description / Recommendation
PASS The basic physical connectivity of the primary D-Chel is intact and
functional. Try this test repeatedly to ensure the link is up and to uncover
any transitory problems.
See NO BOARD for the repair procedures.
Remote Layer 3 Query (#637)
This test will query the far-end switch or terminal adapter to determine whether the signaling
connection is functioning properly at Layer 3. It will select a B-Chel in the in-service or
maintenance service state and send an ISDN layer-3 SERVice message, which requires a
response from the far end. The test will not be performed if there are no B-Chels in an
appropriate ISDN service state (as when none are administered or they are all out of service).
Note:
Note: Enter status trunk grp#/mem# or status pri-endpoint to see the
service state.
A PASS indicates only that a message was successfully sent to the far-end switch or terminal
adapter. The ISDN PRI Specification allows up to 2 minutes for a response.
