Product Overview
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 AVVID
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 (Figure 1). Tables 1 and 2 show the number of voice
channels and codecs that each PVDM2 module supports.
