ATM-TRK (Circuit Emulation Service
Circuit Pack)
This maintenance object expl ains how you test and repair TN230x ATM Interface
circuit packs (TN2305 and TN2306) that have been administered a s virtual
ISDN-PRI trunks for ATM Circuit Emulation Service (CES). The maintenance
instructions for TN230x circuit p acks that have been ad ministered as Expansion
Interfaces for WAN connectivity are in the ATM-EI (Expansion Interface Circuit
Pack) maintenance object.
Description
The TN2305 and TN2306 (Table 9-111) 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” req uires SONET OC-3 or SDH STM-1 fiber cable
connections between the c ircuit pack and the ATM switch. As a trunk board, it
supports direc t connection between ATM CES circuit pac ks without an
intervening ATM switch.
