I am trying to determine which interface module I need to provide a ethernet interface to the 1841. I have a fractional T1 in the one interface, but want to bring in a second network segment from one of my switches. Can someone point me to the correct WIC?

The Cisco 1841 router has two interface card slots. Each slot can accommodate a Cisco WIC, VWIC (data only mode), or a single-wide high-speed WIC (HWIC).

Note Cisco double-wide HWICs are not supported in the Cisco 1841 router.

But I cannot find the list of the allowed modules I would guess NM-1FE2W.

Hope to help

yes Cisco 1841 doesn't support the double-wide form factor (i.e. HWIC-D-9ESW), it supports 2 Single-wide HWICs!
