The Cisco® High-Density Packet Voice Digital Signal Processor (DSP) Module (PVDM2) enables Cisco Integrated Services Routers to provide high-density voice connectivity, conferencing, and transcoding capabilities in Cisco IP Communications solutions. Cisco Integrated Services Routers provide enterprises and service providers with a toll bypass solution by connecting their existing telephony equipment (such as private branch exchanges [PBXs], key systems, analog telephones, and fax machines) to a toll-free data network and eventually migrating customers to Cisco Unified Communication Architecture for Voice, Video and Integrated Data IP telephony solutions.

The high-density packet voice DSP modules are available in five versions: PVDM2-8, PVDM2-16, PVDM2-32, PVDM2-48, and PVDM2-64

Investment Protection and Field-Upgradable Capability
PVDM2 is used across a series of Cisco Integrated Services Routers and high-density voice network modules, allowing users to distribute or reuse DSP resources among the routers or network modules as needed. The field-upgradable capability enables users to easily scale their voice deployments.
In addition, each DSP on the PVDM2 provides four times the processing power and more memory than the existing PVDM. The high performance of PVDM2 supports future growth.

High Density and Flexibility
PVDM2 provides high call density per DSP and flexibility of channel allocation. The maximized support of uncompressed G.711 voice calls optimizes DSP utilization for the solutions, mainly based on G.711 codecs such as IP telephony, in a LAN where the bandwidth consumed by uncompressed calls is not a concern.

Conferencing and Transcoding Services
With PVDM2, Cisco Integrated Services Routers and voice network modules provide both digital and analog voice connections and conferencing and transcoding services. In conjunction with host software, PVDM2 supports universal transcoding when needed. Universal transcoding allows transcoding from any supported codec to any other supported codec. As a general rule, the number of sessions needed for a universal transcoding channel is the sum of the session requirements for two separate voice channels, one running each of the configured codecs. For example, a channel running universal transcoding from a G.729a codec to iLBC would need the session capacity for a voice channel running the G.729a codec and MIPS (million instructions per second) for a voice channel running the iLBC codec.

Improved Voice Quality
PVDM2 performs compression, voice activity detection, jitter management, and echo cancellation functions to improve voice quality. The echo cancellation offered in PVDM2 has a tail length of 64 milliseconds (ms) and complies with International Telecommunication Union (ITU)-T G.168.
