ISDN-SGR (ISDN-PRI Signaling
Group)
An ISDN-PRI Signaling Group is a collection of DS1/UDS1 ISDN Trunks or PRI
endpoint ports (B-channels) for which a given ISDN-PRI Signaling Link Port
(D-channel) carries signaling information. ISDN-PRI requires the use of one of the
following DS1 interface circuit packs:
See DS1-BD and UDS1-BD Maintenance documentation for a description of
these circuit packs. See
DS1/CEPT1/ISDN-PRI Reference
, 55-025-101, for more
information on ISDN.
NOTE:
If a ISDN-PRI over PACCON (Packet Control Circuit pack) is to be used
then only the TN464C or later may be used for the D-channel Signaling.
For 24 channel interfaces, the first 23 ports on the circuit pack are used as
B-channels. The 24th port may be used as a B-channel or as a D-channel
depending on the type of Signaling Group used, as described below.
For 32 channel interfaces, ports 1-15 and 17-31 on the circuit pack are used as
B-channels. The 16th port may be used as a B-channel or as a D-channel
depending on the type of Signaling Group used, as described below.
There are two types of Signaling Groups:
■ Facility Associated Signaling (FAS) (supported by all country protocols)
■ Non-Facility Associated Signaling (NFAS) (supported by country protocol
1 only)
The figures following this discussion illustrate each of the configurations.
