VWIC3-4MFT-T1/E1 Overview The Cisco MFT VWIC3 cards can be inserted into the EHWIC slot on the supported Cisco 1921, 1941, 1941W, 2901, 2911, 2921, 2951, 3925, 3945, 3925E and 3945E integrated services routers. The T1/E1 MFT VWIC3 cards support both T1 and E1, providing additional flexibility in configuring the Cisco MFT VWIC3s for supporting T1, fractional T1, E1, and fractional E1 for both voice and WAN applications. All MFT VWIC3 modules include the drop-and-insert multiplexing capability, which eliminates costly external third-party channel service units/data service units (CSUs/DSUs) and drop-and-insert multiplexers.
