            Ordering Information

            The Cisco Fourth-Generation Packet Voice Digital Signal Processor Module (PVDM4) enables Cisco 4451-X Integrated Services Routers (ISRs) to provide rich- media capabilities such as high-density voice connectivity, conferencing, transcending, media optimization, translating, and secure voice in Cisco Unified Communications Solutions.

            The PVDM4 modules are supported on the Cisco 4451-X platform. You can plug them directly into the single slot on the router motherboard or onto the network inter face module (NIM) that supports T1/E1 ports. Enhanced DSP architecture accommodates a packet-processing engine optimized for rich-media voice applications, while concurrently supporting the time-division multiplexing IP (TDM-IP) voice framework.
