Cisco Network Interface Module - Expansion module - FXS/DID x 4 - for Cisco 4451-X

The Cisco 4000 series integrated services routers (ISRs) host the Cisco network interface modules (NIMs), which have evolved from the enhanced high-speed WAN interface card (EHWIC), increasing port density and module capability.
