The Cisco® High-Density Packet Voice Digital Signal Processor Module (PVDM3) enables Cisco 2900 and 3900 Series Integrated Services Routers Generation 2 (ISR G2) to provide rich-media capabilities such as high-density voice video connectivity, conferencing, transcoding, transrating, and secure voice in Cisco Unified Communications Solutions.
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, with 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.
The PVDM3s are supported on all Cisco 2900 and 3900 Series platforms. The PVDM3 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 and video 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. 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.
