    Product Overview

    The PVDM3 brings new rich-media capabilities to Cisco® Unified Communications Solutions. High-density voice connectivity. Conferencing, transcoding, and transrating. Management of voice quality. Power savings, secure voice, and more. The module resides on the Cisco 2900 and 3900 Series routers to enable these capabilities.

    The next-generation high-density packet voice digital-signal-processor (DSP) modules are available in six densities: PVDM3-16, PVDM3-32, PVDM3-64, PVDM3-128, PVDM3-192, and PVDM3-256. The modules have
    16, 32, 64, 128, 192, and 256 channels, respectively (Figure 1). Tables 1 and 2 show the number of voice channels and codecs that each PVDM3 module supports.

    Features and Benefits

    The Cisco High-Density Packet Voice Digital Signal Processor Module (PVDM3) is supported on all Cisco 2900 and 3900 Series platforms, part of the Cisco Integrated Services Routers Generation 2 (ISR G2) portfolio.
    It provides higher density and more processing power than the PVDM2, making the addition of rich-media applications possible. Enhanced DSP architecture accommodates a new packet-processing engine optimized for rich-media voice applications, while concurrently supporting the time-division multiplexing IP (TDM-IP) voice framework used by the PVDM2.

    Investment Protection and Field-Upgradable Capability

    You can now choose a DSP module ranging from 16 to 256 G.711 channels from the PVDM3 module portfolio. The PVDM3 modules all have the same form factor, and are used across Cisco 2900 and 3900 Series Integrated Services Routers (ISRs). The field-upgradable capability can help you easily scale your voice deployments.

    In addition, DSPs on the PVDM3 provide more processing power and memory than the DSPs on the PVDM2.
    The high performance of PVDM3 supports future voice and video growth with a simple image upgrade to eliminate complete system upgrades. The PVDM3 modules can not only meet your needs today but also anticipate your needs in the future.

    Wide Range of Codec Support

    The PVDM3 modules support a wide range of codecs of different complexities. They support all codecs that are supported by the PVDM2 modules. Table 1 lists the codecs supported on the PVDM3 modules.

    High Density and Flexibility

    The PVDM3 modules have up to four times higher density than the PVDM2 modules. In addition, the PVDM3 modules provide better density for medium- and high-complexity codecs than their equivalent PVDM2 peers. For example, the number of supported medium-complexity codecs on a PVDM3-64 is 42, versus 32 on a PVDM2-64. Refer to Table 2 for more details about channel density for each PVDM3 module.

    High-end PVDM3 modules such as the PVDM3-192 and PVDM3-256 enable scalable rich-media applications with improved user experience and quality. A PVDM3-256 can support up to 60 secure iLBC TDM-IP voice sessions, and up to 30 eight-party conferences with the high-fidelity wideband codec G.722.

    Conferencing, Transcoding, and Transrating Services

    The PVDM3 modules support digital voice connections, analog voice connections, conferencing, and universal transcoding services. The same DSPs on the PVDM3 modules can now support all the services with a single DSP image. In addition, the PVDM3 supports a higher number of conference sessions and a higher number of participants per conference than the PVDM2. The PVDM3-256 can support up to 6 conferences with 64 participants in each conference and up to 66 conferences with 8 participants in each conference. Please refer to the PVDM3 Q&A for more information about the number of supported sessions.

    In conjunction with Cisco IOS® Software, the PVDM3 modules support universal transcoding and the same codec repacketization as the PVDM2 modules. Universal transcoding allows transcoding from any supported codec to any other supported codec. The PVDM3 modules offer improved universal transcoding session capacity over the PVDM2 modules. Please refer to the PVDM3 Q&A for more details about the number of supported sessions for each codec on each PVDM3 module.

    The PVDM3 modules support transrating, where repacketization of the same codec is used to connect dissimilar networks that have different codec packetization periods.

    Voice-Quality Management

    The PVDM3 modules perform compression, voice-activity-detection, jitter-management, and echo-cancellation functions. The echo cancellation offered in the PVDM3 modules has a tail length of 128 milliseconds (ms) and complies with ITU-T G.168.

    Energy-Saving Feature

    The PVDM3 DSPs offer multiple power-saving modes, including a power-saver mode when the module is not in use. In power-saver mode each PVDM3 can save up to 5 watts of power.
