Cisco Network Module VWIC3-1MFT-T1/E1 Voice WAN Interface Card Expansion Module

Product Information

^{The Cisco 1-, 2- and 4-port MFT VWIC3 interface cards simplify branch-office connectivity by helping enable Cisco 2900 and 3900 routers to consolidate the functions of a router, a fully managed drop-and-insert multiplexer, and a fully managed DSU/CSU into a single box. (It is possible to use two Cisco 1-port MFT VWIC3 interface cards for supporting the drop-and-insert feature. Generally, a Cisco 2- or 4-port MFT VWIC3 is more appropriate because at least 2 ports are required.) Typically a drop-and-insert multiplexer is used for channelized (that is, TDM) integration of data and voice onto a single T1, fractional T1, E1, or fractional E1 connection to the central office. Sharing a line can significantly reduce costs over those of two separate physical lines to the central office. Although the normal use is for data and voice sharing of a T1 or E1 service, the drop-and-insert capability also can be used for video and data, or data and data sharing of the service.}
