— DS1 (T1) Circuit Pack
Assign all fields as required. For Facility Associated Signaling, up
to 23 ports are available for administration as trunk members in an
associated ISDN-PRI trunk group. The 24th port is used as a
signaling channel. For Non-Facility Associated Signaling, all 24
ports may be used on certain DS1 circuit packs. The D-channel
signaling function for these packs must be provided by a designated
DS1 pack on its 24th channel.

Signaling Group — This screen is required if ISDN-PRI interfaces are
used. Complete all fields. This screen identifies groups of ISDN-PRI DS1
interface B-channels for which a given D-channel (or D-channel pair) will
carry the associated signaling information (supports the Facility and
Non-Facility Associated Signaling feature). Each DS1 board that is
required to have a D-channel must be in a different signaling group by itself
(unless D-channel backup is needed, in which case a second DS1 is
administered as a backup D-channel). You are not required to select a
channel for a trunk group, but if you do, you must have already defined the
trunk group as type ISDN.

NOTE:
The following three screens, Processor Interface Data Module,
Communication Interface Links, and Communication Processor
Channel Assignment are used only to support the ISDN-PRI
interfaces using PI TN765.
