Cisco VWIC-2MFT-E1-DI enterprise networking (router/Catalyst switch/UCS families) Router Line Card

The Cisco VWIC-2MFT-E1-DI is a 2-port RJ-48 multiflex trunk voice/WAN interface card for E1 circuits, with drop-and-insert capability. It fits the WIC/VWIC slots on Cisco’s modular access routers and provides two independent E1 trunk ports that can each be channelized for voice, data or a mixed configuration.

The drop-and-insert feature lets the card pass a channelized E1 circuit through to a second device, such as a PBX, while dropping selected timeslots for the router’s own use, avoiding the need for a separate external multiplexer. This makes the card a common choice in voice-gateway and branch-office deployments where an E1 circuit needs to serve both the router and an existing telephony system. Established Cisco access-router estates using channelized E1 trunking still rely on cards of this type. Tech-Star (UK-based, shipped worldwide) inspects and tests each unit before dispatch; confirm compatibility with your specific chassis before ordering.
