Secondary Signaling Link Hardware
Check (#639)
The ISDN-PRI Signaling Group D-channel port depends on the health of the TN464C or higher
suffix UDS1 Interface circuit pack or MM710 DS1 Interface Media Module on which it resides.
This test will fail if there are problems with the ISDN-PRI Secondary D-channel port, or the
UDS1 circuit pack, or the MM710 DS1 Media Module. This test will abort if a Secondary D
channel is not administered for the signaling group. If there are problems with the ISDN-PRI
Secondary Signaling Channel port (ISDN-LNK), also investigate the UDS1 circuit pack
1132 ABRT
The Secondary D channel is not administered for this Signaling Group. This is
a NORMAL ABORT. Only a Primary D channel must be administered for a Signaling Group.
