The VWIC2-1MFT-T1/E1 is a Cisco Voice/WAN Interface Card (VWIC) that provides T1/E1 connectivity for Cisco routers. It’s designed to support voice and data traffic over traditional TDM (Time Division Multiplexing) lines. This card is commonly used in environments where integration with legacy telephony systems is required. It allows Cisco routers to connect to T1 or E1 circuits, which are digital telecommunications lines used for carrying voice and data.
