ATM-SGRP (ATM Signaling Group)

ATM-SGRP (ATM Signaling Group)
This ATM-SGRP MO applies when ATM signaling groups have been administered
on an ATM circuit pack as ATM trunks.
Table 8-104 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
‘‘ATM-TRK (Circuit Emulation Service Circuit Pack)’’ .
The operation of the entire ATM signaling group depends on several other
entities:
■
ATM-DCH signaling-channel port
■
TN230X Interface circuit pack where a D channel resides
■
System link to the processor via the packet bus
