The Cisco NM-1HSSI is a single-port High-Speed Serial Interface (HSSI) network module for Cisco’s 2600, 3600 and 3700 series modular access routers, providing WAN connectivity at speeds of up to 52Mbps over a 50-pin HSSI connector. HSSI was the standard interface for connecting a router to high-bandwidth WAN services such as T3/E3 circuits or ATM/Frame Relay access at rates beyond what a standard serial WIC could support, making this module a common choice for head-office or data-centre routers needing a fast WAN uplink rather than multiple lower-speed links. It occupies the network-module slot alongside Ethernet and voice modules fitted in the same chassis. These routers remain in service across many established WAN edge deployments, and a genuine spare such as this restores a failed high-speed WAN link. Tech-Star (UK-based, shipped worldwide) stocks Cisco network modules for engineers maintaining these platforms.
