ATM-SGRP (ATM Signaling Group)
This Maintenance Object (ATM-SGRP) applies when ATM signaling groups have
been administered on an ATM circuit pack as ATM Trunks.

outlines the differences between ATM interface circuit packs:
The TN2305 and TN2306 ATM Interface circuit boards are referred to as TN230X

for the remainder of this MO.
An ATM Signaling Group is a collection of B-channels for which a given ISDN-PRI
Signaling Channel Port (ATM D-channel) carries signaling information. ATM
B-channels (ATM-BCH) carry voice or data and are assigned to ISDN trunks. For
more information see

.
The operation of the entire ATM signaling group depends on several other
entities:
entities:
■
the ATM-DCH signaling channel port
■
the TN230X Interface circuit pack on which the D-channels reside
■
the system link that is carried over the packet bus to the processor
