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:

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.

The TN464C/D UDS1 Interface circuit pack and MM710 DS1 Interface Media Module, which 
have a direct interface to the packet bus, are required for D-channel signaling. 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.

1. grp# is the signaling group number (1–166); the test sequence can be either short or long.
