The VWIC2-1MFT-T1/E1 is a Cisco Voice/WAN Interface Card (VWIC) designed to provide T1/E1 connectivity for Cisco routers. It’s used to integrate traditional time-division multiplexing (TDM) voice and data circuits into IP networks. This card allows routers to connect to T1 or E1 lines, which are digital telecommunications lines commonly used for voice and data transmission. It’s essential for environments requiring connectivity to legacy telecommunications infrastructure.
