Full Description


The Cisco Third-Generation 4-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.
