Cisco MFT VWIC3 cards plug into EHWIC slots on Cisco 1921, 1941, 1941W, 2901, 2911, 2921, 2951, 3925, 3945, 3925E, and 3945E routers. The T1 / E1 MFT VWIC3 cards support both T1 and E1 and provide more flexibility in configuring the Cisco MFT VWIC3 to provide slight support for T1, T1, E1 and E1 for audio and broadband applications. All VWIC3 MFTs have drop-and-insert capabilities that eliminate the cost of external channel servers / data servers (CSUs / DSUs) and multiple drop-and-inserts.
