ATM-TRK (Circuit Emulation Service
Circuit Pack)
This maintenance object 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-EI (Expansion Interface Circuit
Pack) maintenance object.
Description
The TN2305 and TN2306 (Table 3-95) 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-EI) for Port Network Connectivity (ATM-PNC)
between the PPN and 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.
