Cisco VIC-4FXS/DID

The 4-port High-Density FXS/DID Interface Card can support up to 4 foreign-exchange-station (FXS) ports for directly connecting phones or fax machines, or it can be used to connect up to four direct-inward-dial (DID) analog trunks, providing customers the flexibility they need for their unique business environment . Each port on the 4-Port FXS/DID VIC is selectable for use in either FXS or DID mode. The 4-Port FXS/DID VIC is the same size as the existing two-port voice interface cards (VICs), allowing it to slide into either WIC/VIC slot or VIC slot in Cisco 1751 and 1760
