ATM-TRK (Circuit Emulation Service
Circuit Pack)
This MO explains how you test and repair TN230x ATM Interface circuit packs
(TN2305 and TN2306) that have been administered as virtual ISDN-PRI trunks for
ATM Circuit Emulation Service (CES). The maintenance instructions for TN230x
circuit packs that have been administered as Expansion Interfaces for WAN
connectivity are in the ATM-INTF (TN2305/6) MO.
Description
The TN2305 and TN2306 (
) are dual-purpose ATM
circuit packs that can be administered as either personality:
■
‘‘ATM Circuit Emulation Service’’
or virtual ISDN-PRI signaling trunks
■
Expansion Interfaces (ATM-EIs) for port-network connectivity (ATM PNC)
between the EPNs
Either circuit pack “personality” requires SONET OC-3 or SDH STM-1 fiber cable
connections between the circuit pack and the ATM switch. As a trunk board, it
supports direct connection between ATM CES circuit packs without an intervening
ATM switch.
