More info from Cisco:
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.PVDM2 connects to the host through 80-pin single inline memory module (SIMM) slots. The module is field insertable and removable.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.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.
