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:
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
