The Cisco Third-Generation 1-, 2-, and 4-Port T1/E1 Multiflex Trunk Voice/WAN Interface Cards (MFT VWIC3s) support data and voice applications on the Cisco 1900, 2900, 3900, and 3900E Series 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. 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. These interface cards add improvements over the previous generation (MFT VWIC2), including enhanced clocking capabilities that enable each port to be clocked from an independent clock source for data applications, and independent clocking for voice and data applications.
