The CiscoSecond-generation 1- and 2-port T1/E1 Multiflex Trunk Voice/WAN
Interface (MFT VWIC2s) support data and voice applications on the
Cisco 1721 (data only), 1751 and 1760 Modular Access Routers, the
Cisco 2600XM Multiservice Router, the Cisco 2691 Multiservice
Platform, the Cisco 3662 Telco Versatile DCN Access Platform, the
Cisco 3725 and 3745 Multiservice Routers, and the Cisco 1841 (data
only), 2801, 2811, 2821, 2851, 3825, and 3845 Integrated Services
Routers. The Cisco MFT VWIC2 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 VWIC2 cards can be reused in packet voice
applications. The 2 port T1/E1 MFT VWIC2 is shown below.
