ATM-SGRP (ATM Signaling Group)
S8700 | 8710 / S8500
ATM-SGRP applies when ATM signaling groups have been administered on an ATM circuit
pack as ATM trunks.
Table 195: R7 ATM-SGR circuit packs
on page 598 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 ATM-SGRP.
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)
on page 617.
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
When there are problems with ATM-SGRP (ATM signaling group), also investigate:
● ATM-DCH (ATM D-Channel Port)
● ATM-BCH (ATM B-Channel Trunk)
● SYS-LINK (System Links)
● PKT-BUS (Packet Bus)
