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. 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 migrate customers to Cisco AVVID (Architecture for Voice, Video and Integrated Data) IP telephony solutions.
