The VWIC-2MFT-E1 is a Cisco 2-port E1 multiflex trunk voice/WAN interface card with an integrated channel service unit/data service unit. Each port works as a trunk interface for voice and data, or as fractional n x 64-kbps service for Frame Relay and leased-line WANs.
When both ports are set to clock source line, they must use the same clock source, otherwise timing slips can occur. Independent clock sources per port belong to the VWIC2-2MFT-T1/E1 and VWIC2-2MFT-G703 cards instead.
Related 2-port cards in the family are the VWIC-2MFT-E1-DI with drop-and-insert capability, the VWIC-2MFT-G703 for unstructured G.703 E1 traffic and the VWIC-2MFT-T1. The 1-port E1 card is the VWIC-1MFT-E1, and a straight-through RJ-48C-to-RJ-48C cable joins a port to the wall jack.
More voice and WAN cards for Cisco access routers are in Cisco interface cards, and the routers that take them are in Cisco routers.
