High-Density Packet Voice Digital Signal Processor Module for Cisco
Unified Communications Solutions
Unified Communications Solutions
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 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 (Figure 1). Tables 1 and 2 show the number of voice channels and codecs that each
PVDM2 module supports.
