The NM-2W is the Cisco 2 WAN card slot network module: two interface card slots and no LAN ports. It fits the network module slot of Cisco 2600, 3600, 3700 and 3800 series routers, and the Cisco MWR 1941-DC.
Both slots take WAN interface cards. A WIC-2T in an NM-2W runs one port at 8 Mbps or two ports at 4 Mbps each, and all other WIC ports on that module must not be used. High-density WAN interface cards (HWICs) are not supported on 1- and 2-slot network modules.
For the Telcordia GR-1089 NEBS standard, the NM-2W connects only to intrabuilding or nonexposed wiring, and the intrabuilding cable must be shielded with the shield grounded at both ends.
The NM-1E2W adds one Ethernet port and the NM-2E2W adds two Ethernet ports to the same two-slot design, while the NM-1FE2W, NM-2FE2W and NM-1FE1R2W add Fast Ethernet. More network modules and interface cards are in Cisco interface cards.
