Information
The Cisco VWIC-2MFT-T1-DIR Voice/WAN Interface Card supports data applications on the Cisco MWR 1941-DC Mobile Wireless Edge Router for T1 networks. This card is a dual-port, T1/Fractional T1, Drop and Insert Multiplexer with integrated T1 CSU/DSUs. The T1 version supports framed and unframed traffic.
