    The Cisco® Packet Voice Digital Signal Processor Modules (PVDMs)

    The Cisco® Packet Voice Digital Signal Processor Modules (PVDMs) are essential components for Cisco 4000 Series Integrated Services Routers (ISRs) to provide advanced voice capabilities. These modules enable high-density voice connectivity, conferencing, transcoding, media optimization, transrating, and secure voice for Cisco Unified Communications solutions. With the PVDMs, users can experience unprecedented scale and a smaller solution footprint than ever before.

    Support for Digital Voice Connections, Conferencing, and Media Optimization

    The PVDMs support a wide range of digital voice applications, including T1/E1 voice, conferencing, universal transcoding, and transrating. These modules packetize digital voice into IP packets, enabling time-division multiplexing (TDM) digital voice applications. They also support ad hoc and meet-me conferencing with various codecs, as well as universal transcoding, which allows conversion from any supported codec to any other supported codec. Additionally, the PVDMs perform compression, voice-activity detection, jitter management, and echo cancellation for optimal voice quality.

    Energy-Saving Features

    The PVDMs offer multiple power-saving modes, including a power-saver mode when the module is not in use. In power-saver mode, each PVDM can save up to 5 watts of power. This feature helps reduce energy consumption and lowers operating costs.

    Analog and Digital Voice Modules

    The PVDMs are compatible with analog voice modules (FXS, FXO, and E/M) and Basic Rate Interface (BRI) digital voice modules for the 4000 Series ISRs. These modules contain built-in, nonconfigurable digital signal processors (DSPs) and do not require any additional PVDMs for voice packetization.
