The multiservice route processor (MRP) card is a voice- and data-capable router that supports both digital and analog voice trunks and WAN routing interfaces. Using the MRP you can link remote Ethernet LANs to the Public Switched Telephone Network (PSTN) and existing private branch exchanges (PBXs), as well as most common analog devices such as fax machines and teleconferencing stations. The MRP card accepts voice interface cards (VICs), WAN interface cards (WICs), and voice WAN interface cards (VWICs) for complete integration of voice and data networking.
