ATM-TRK (Circuit Emulation Service Circuit Pack)
ATM-TRK explains how to 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 ATM-INTF (ATM Interface)
Description
The TN2305 and TN2306 (Table 51: ATM-TRK circuit packs) are dual-purpose ATM circuit
packs that can be administered as either:
● ATM Circuit Emulation Service or virtual ISDN-PRI signaling trunks
● Expansion Interfaces (ATM-EIs) for port-network connectivity (ATM PNC) between the
PNs
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.

Under ATM Circuit Emulation Service (CES), simulate ISDN-PRI circuits by assigning ports to
signaling groups. Each signaling group represents a PRI circuit, and the ports in the group
represent the D-Chel and B-Chels of that circuit.
