The High-Density Packet Voice digital signal processor (DSP) Module (PVDM2) enables Cisco Systems Integrated Services Routers to provide high-density voice connectivity, conferencing, and transcoding capabilities in Cisco IP Communications solutions.
PVDM2 allows 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 deployment. In addition, each DSP on the PVDM2 provides four times the processing power and higher memory than that on the existing PVDM. The high performance of PVDM2 supports future growth.
