Cisco Voice / fax module - analog ports: 4 - Product Details
The high-density Cisco 4-port FXS/DID VIC can support up to four 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 Cisco 4-port FXS/DID VIC is selectable for use in either FXS or DID mode. Because the Cisco 4-port FXS/DID VIC is the same size as the existing 2-port voice/WAN interface cards (VWICs), it can slide into either one of the two VWIC slots located on the MRP card. Thus, when installing two Cisco VIC-FXS/DID cards within a single MRP, any combination of up to eight FXS or DID ports can be supported.
