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.

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 Packet Interface is used, consult the procedures for PKT-INT.

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.
