ISDN-TRK (DS1 ISDN Trunk)
Issue 4 May 2002
10-993555-233-123
Signaling Link State Check Test (#255)
As noted in the general description for a DS1 ISDN Trunk, it depends on the
health of the DS1/UDS1 interface circuit pack and the ISDN-PRI D-channel
(ISDN-LNK/ISDN-PLK) trunk for proper operation. This test checks the status of
those critical elements.

Result Description/Recommendation
ABORT Internal system error
1018 ABORT Maintenance is disable on this trunk.
1. Enable maintenance by entering “y” in the “Maintenance
Tests?” field on page 2 of the change trunk-group form.
1114 ABORT The signaling link is in a transitional state.
1. Retry the command at 1-minute intervals a maximum of 5
times.
4 FAIL There is a problem with the Signaling Channel.
1. If the Packet Control circuit pack is used consult the
procedures for the ISDN-PRI Signaling Group
(ISDN-SGR). Further information may also be obtained by
consulting the procedures for the ISDN-PRI Signaling
Channel (ISDN-PLK).
2. If the Processor Interface is used consult the procedures
for Processor Interface Link (PI-LINK).
8 FAIL There is a problem with the DS1 interface circuit pack.
1. Consult the procedures for DS1 interface circuit pack
(DS1-BD/UDS1-BD).
PASS The signaling link hardware is OK.
