An ISDN-PRI Signaling Group is a collection of B-Channels for which a given ISDN-PRI
Signaling Channel Port (D-channel) carries signaling information. B-Channels carry voice or
data and can be assigned to DS1 ISDN trunks (ISDN-TRK) or PRI endpoint ports (PE-BCHL).
Note:
Note: Throughout this discussion, the term “B-Channel” refers to an ISDN-TRK or
PE-BCHL, depending on the application under investigation.
The following circuit packs/media modules are supported in the implementation of ISDN-PRI:
. There are two types of DS1 interfaces:
● 24 DS0 channels on a 1.544-Mbps link
● 31 DS0 channels + 1 framing channel on a 2.048-Mbps link
The following discussion describes 24-channel interface signaling groups. The 32-channel
interface works the same way, except that only port number 16 is used for signaling instead of
port number 24. Ports 1 through 15 and 17 through 31 are used for B-Channels. The 32 nd
channel (port 0) is always used for framing.
ISDN-PRI D-channel signaling can be combined with a group of B-Channels in three basic
ways:
● FAS (facility-associated signaling)
● NFAS (non-facility-associated signaling)
● Backup NFAS signaling
