The Cisco NM-2W is a 2-slot WAN network module designed for Cisco routers, providing flexible expansion for WAN interface cards (WICs). Unlike combo modules, it does not include any LAN ports, focusing entirely on WAN connectivity.
It enables routers to support multiple WAN technologies such as serial, ISDN, DSL, or leased-line interfaces, depending on the installed WIC cards. This makes it ideal for branch office connectivity, multi-WAN routing, and legacy telecom integrations.
