VWIC3-1MFT-T1/E1

The Cisco Third-generation 1-, 2-pt and 4-pt T1/E1 Multiflex Trunk Voice/WAN Interface (MFT VWIC3s) suppt 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 interface cards add improvements over the Cisco Second-generation 1- and 2-pt T1/E1 Multiflex Voice/WAN Interface Cards (MFT VWIC2s). The Cisco 2- and 4-pt MFT VWIC3s enable each pt to be clocked from an independent clock source f data applications. Voice applications can now be clocked independently from data applications, with all pts f voice applications clocked from a single source. The Cisco MFT VWIC3s use the ECAN on the motherboard PVDM cards with up to 128ms echo-tail length f demanding netwk conditions. MFT VWIC3 cards suppt up to 2 channel groups per T1/E1 pt f serial data applications. Refer to Table 3 f all configuration options offered with the MFT VWIC3 cards.

The Cisco MFT VWIC3 cards can be inserted into the EHWIC slot on the suppted Cisco 1921, 1941, 1941W, 2901, 2911, 2921, 2951, 3925, 3945, 3925E and 3945E integrated services routers. The T1/E1 MFT VWIC3 cards suppt both T1 and E1, providing additional flexibility in configuring the Cisco MFT VWIC3s f suppting T1, fractional T1, E1, and fractional E1 f 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.

The Cisco MFT VWIC3 cards are offered in single-, dual- and quadruple-pt versions, which can be used and then redeployed as netwk requirements change, thereby addressing several applications:

• T1/E1 data: The Cisco 1-, 2- and 4-pt T1/E1 MFT VWIC3 versions act as a WIC, suppting T1, fractional T1, E1, (including structured G.703 with G.704 framing), fractional E1, and E1structured G.703 applications. To simplify remote management, these MFT VWIC3 cards integrate a fully managed DSU/CSU f T1 deployments and a fully managed DSU f E1 deployments.
• E1/G.703 data: The Cisco 1- and 2- pt G.703 MFT VWIC3 versions act as a WIC, suppting T1, fractional T1, E1 (including structured G.703 with G.704 framing), fractional E1, and unstructured E1 (G.703) applications. To simplify remote management, the G.703 version includes a fully managed DSU. The G.703 versions also suppt all the capabilities on the T1/E1 versions.
• T1/E1 packet voice: The Cisco 1-, 2- and 4-pt T1/E1 MFT VWIC3 (voice and WAN) versions act as a VIC, suppting packet voice applications by providing T1, fractional T1, E1, and fractional E1 connections to private branch exchanges (PBXs) and central offices, thereby enabling new services and reducing voice and fax toll charges.
• Mixed data and packet voice: The Cisco MFT VWIC3 interface cards can simultaneously suppt both data and voice, reducing the complexity and number of netwk components and facilitating a graceful migration to bandwidth-efficient packet voice.
• Mixed data and packet voice with drop and insert: The Cisco MFT VWIC3 cards can be deployed as a T1/E1 drop-and-insert multiplexer with integrated DSUs/CSUs, reducing the complexity of the netwk and the cost of the central-office pts by efficiently combining time-division multiplexing (TDM) voice (PBX), IP voice, and data on the same trunks. Cisco 1900, 2900 and 3900 ISR routers suppt drop and insert between pts over a single MFT VWIC3 card and two pts over two different MFT VWIC3s
