The Cisco Third-Generation 2-Port T1/E1 Multiflex Trunk Voice/WAN Interface supports data and voice applications. 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.
Reduces networking lifecycle costs
It enables graceful migration from data - only to multiplexed data and voice to packetized voice applications, reduces training, deployment, management, and sparing inventory over single-purpose interfaces, and maximizes investment protection. It simplifies network configuration and sparing through the support of both T1 and E1 on the same card, offers multifunction support for LAN-to-LAN routing, multiplexed data and voice, and packetized voice, increases configuration flexibility and reduces cost for data applications by allowing individual ports to be clocked from independent clock sources.
Maximizes system resources
It increases T1/E1 port density on the supported integrated services routers - up to two T1/E1 connections with an integrated CSU/DSU in a single EHWIC slot. Also it offers easy migration to bandwidth-efficient packet voice.
