Cisco VWIC-1MFT-T1/E1 enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco VWIC-1MFT-T1/E1 is a single-port Multiflex Trunk (MFT) interface card fitted with an RJ-48 connector, configurable in software to run either T1 or E1 framing. It fits the WIC/VWIC slots on Cisco 2600, 3600, 2800 and 3800 Series routers (and compatible later platforms) and can carry either a data trunk for WAN connectivity or channelised voice trunks (CAS or PRI/ISDN signalling) for a router running Cisco Unified Communications features, which is what the “V” in VWIC signifies. Because it supports both T1 and E1 electrical standards from the same card, it is a common stock item for organisations with mixed North American and international sites, or resellers who cannot predict which framing a given customer needs until the card ships. It is a first-generation VWIC, distinct in electrical specification from the later VWIC2 and VWIC3 families used on ISR G2 platforms. Tech-Star (UK-based, shipped worldwide) stocks Cisco components to support ongoing network maintenance.
