The Cisco SPA-2CHT3-CE-ATM Network Interface Module is a two-port NIM for Cisco's SPA platform that provides channelized T3/E3 circuit-emulation over packet networks and channelized ATM. It is designed to be used in Cisco SPA routers to carry T3 or E3 CE traffic and ATM channels, enabling legacy services to operate over modern transport networks. The module’s two ports support T3/E3 CE over Packet and Channelized ATM, making it suitable for integrating traditional TDM and ATM services within a Cisco SPA deployment.
