ATM-SGRP (ATM Signaling Group)
This Maintenance Object (ATM-SGRP) applies when ATM signaling groups have
been administered on an ATM circuit p ack as ATM Trunks.
Table 9-100 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-c hannels 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 ‘‘ATM-TRK (Circuit Emulation Service Circuit Pack)’’.
The operation of the entire ATM signaling group dep ends on several other
entities:
■the ATM-DCH signaling channel port
■the TN230X Interface circuit pack o n which the D-channels reside
■the system link that is carried over the p acket bus to the proc essor
