Cisco NM-1A-T3 enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco NM-1A-T3 is a 1-port DS3 ATM network module for Cisco’s modular access routers (2600, 3600 and 3700 series), adding a single ATM interface over a DS3 (T3, 44.736 Mbps) circuit to the host router. It fits one of the router’s network module slots and gives the platform ATM uplink capacity for WAN aggregation, service-provider access or campus ATM backbone connections where a T3-rate ATM circuit is required, working alongside the router’s other network modules and WAN interface cards. This is a widely deployed legacy WAN module and genuine spares are routinely needed to maintain full port capacity on routers already running this card, restore a failed unit, or add ATM connectivity to a router that does not yet have it. Specifiers should confirm the exact host router model and IOS feature set support ATM/DS3 network modules before ordering. Tech-Star (UK-based, shipped worldwide) stocks Cisco WAN modules to support ongoing network maintenance projects.
