The Cisco Third-generation 1-, 2-port and 4-port T1/E1 Multiflex Trunk Voice/WAN Interface (MFT VWIC3s) support data and voice applications on the Cisco 1921, 1941 and 1941W (data only), and the Cisco 2901, 2911, 2921, 2951, 3925, 3945, 3925E and 3945E Integrated Services Routers. The Cisco MFT VWIC3 combines WAN-interface-card (WIC) and voice-interface-card (VIC) functions to provide unparalleled flexibility, versatility, and investment protection through its many uses. Customers who choose to integrate data and voice in multiple steps preserve their investment in a T1/E1 WAN interface because the Cisco MFT VWIC3 cards can be reused in packet voice applications.
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.
