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, 555-025-101, for
more information on ISDN.
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 (see
Figure 33
).
