Data Sheet Cisco Third-Generation 1-, 2-, and 4-Port T1/E1 Multiflex Trunk Voice/WAN Interface Cards These flexible interface cards support multiple integrated data, voice and video applications, facilitating the migration from data only as well as circuit-switched voice/video services to a packet voice/video solution Introduction ® The Cisco Third-generation 1-, 2-port and 4-port T1/E1 Multiflex Trunk Voice/WAN Interface (MFT VWIC3s) support 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 2 port T1/E1 MFT VWIC3 is shown below. Figure 1. Cisco 1-,2- and 4-Port T1/E1 MFT VWIC3 The Cisco MFT VWIC3 interface cards add improvements over the Cisco Second-generation 1- and 2-port T1/E1 Multiflex Voice/WAN Interface Cards (MFT VWIC2s). The Cisco 2- and 4-port MFT VWIC3s enable each port to be clocked from an independent clock source for data applications. Voice applications can now be clocked independently from data applications, with all ports for 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 for demanding network conditions. MFT VWIC3 cards support up to 2 channel groups per T1/E1 port for serial data applications. Refer to Table 3 for all configuration options offered with the MFT VWIC3 cards. The Cisco MFT VWIC3 cards can be inserted into the EHWIC slot on the supported Cisco 1921, 1941, 1941W, 2901, 2911, 2921, 2951, 3925, 3945, 3925E and 3945E integrated services routers. The T1/E1 MFT VWIC3 cards support both T1 and E1, providing additional flexibility in configuring the Cisco MFT VWIC3s for supporting T1, fractional T1, E1, and fractional E1 for both voice and WAN applications. All MFT VWIC3 modules include the dropand-insert multiplexing capability, which eliminates costly external third-party channel service units/data service units (CSUs/DSUs) and drop-and-insert multiplexers. © 2010 Cisco and/or its affiliates.

Data Sheet The Cisco MFT VWIC3 cards are offered in single-, dual- and quadruple-port versions, which can be used and then redeployed as network requirements change, thereby addressing several applications: ● T1/E1 data: The Cisco 1-, 2- and 4-port T1/E1 MFT VWIC3 versions act as a WIC, supporting 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 for T1 deployments and a fully managed DSU for E1 deployments. ● E1/G.703 data: The...

Data Sheet ● Offers easy migration to bandwidth-efficient packet voice, enabling new services Customers can choose to integrate data and voice in stages to preserve their investment in WAN interfaces. For example, the Cisco MFT VWIC3 can support data-only applications as a WAN interface, and then be reused to integrate data and voice with the drop-and-insert multiplexer function or configured to support packetized voice (voice over IP [VoIP] or voice over Frame Relay [VoFR]).

Data Sheet is for data and voice sharing of a T1 or E1 service, the drop-and-insert capability also can be used for video and data, or data and data sharing of the service. Moreover, the integrated drop-and-insert capability enhances system availability by allowing the Cisco IOS Software to be reloaded while maintaining TDM switching. Figure 2. Drop and Insert to Share a T1/FT1 or E1/FE1 Service between Data and TDM To illustrate, consider the example of a PBX with a T1 interface that needs to support a maximum of 10 simultaneous calls. With 24 DS-0 channels in a T1 service (1.544 Mbps),...
