Cisco Module PVDM2-48

Fully Refurbished and Tested with Lifetime Warranty

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.
