ATM-TRK (Circuit Emulation Service Circuit Pack)
Issue 1 June 2005 617
ATM-TRK (Circuit Emulation Service
Circuit Pack)
S8700 | 8710 / S8500
ATM-TRK 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 (Table 205: R7 ATM-TRK circuit packs on page 617) 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.
