The VWIC2-2MFT-G703 is a Cisco 2-port G.703 multiflex trunk voice/WAN interface card, used to support unstructured E1 (G.703) and all the features of the other Cisco MFT VWIC2 modules, including drop-and-insert. With two ports, one can be set for unstructured E1 (G.703) while the other runs standard framed E1.
The recommended echo cancellation module for this card is the 64-channel EC-MFT-64, a daughter card that attaches to the VWIC2 and allows an echo tail of 128 ms. That module is not supported when the card is used on a Cisco 1751 or 1760.
The Cisco VWICs are daughter cards that provide the interface to the PBX, PSTN and WAN. As a VWIC it installs in the VIC/VWIC slot of the NM-HDV2, NM-HDV2-1T1/E1 and NM-HDV2-2T1/E1 high-density digital voice/fax network modules, which are for the Cisco 2811, 2821, 2851, 2911, 2921, 2951, 3825, 3845, 3925 and 3945 routers. Its T1/E1 counterpart is the VWIC2-2MFT-T1/E1, and the Cisco interface card category holds other voice and WAN cards.
