Use list signaling-group to see a list of signaling groups, which are groups of B-Channels for which a given D-Channel (or D-Channel pair) will carry the signaling information.
Syntax
list signaling-groupcount x
count x
The number of signaling groups to be displayed.
Example
list signaling-group count 6
list signaling-group field descriptions
Field
Description
Grp No
The signaling group number
Group Type
The type of signal format (ISDN-PRI, H.323)
FAS
Facility Associated Signaling (FAS), in which a D-Channel carries signaling information for only those B-Channels on the same facility as the D-Channel. This is identical to a DS1 interface. If the parameter is “n”, this is referred to as Non-Facility Associated Signaling (NFAS), in which a B-Channel can belong to any signaling group as long as the maximum number of DS1’s for a signaling group is not exceeded.
No. Trunk Brds
The number of trunk boards having members belonging to this signaling group
Primary D-Channel
The D-Channel administered to be the primary channel. If, during the backup procedure, both channels are in the same state, switches at opposite ends of the PRI select the primary D-Channel to be put into service.
Secondary D-Channel
This channel will only display if the signaling group is an NFAS signaling group. This D-Channel is administered to be the secondary D-Channel. If, during the backup procedure, both channels are in the same state, switches at opposite ends of the PRI select the primary D-Channel to be put into service.
Max NCA TSCs
Maximum number of Non-Call Associated (NCA) Temporary Signaling Connections (TSCs) — virtual connections established within a D-Channel in the facility so that users can transport non-call control user-user information.
