Product Description
CISCO PVDM3-32
Details : Cisco Systems PVDM3-32 32-channel high-density voice and video DSP module
The Cisco PVDM3-32 (High Density Packet Voice Digital Signal Processor Module) allows Cisco 2900 and 3900 series routers to provide high quality communication services, such as high density voice and video, conferencing, and secure voice through the Cisco Unified Communications Solutions (UCS) platform. PVDM3-32 DSPs also perform compression, jitter and echo management, and voice-activity detection to reduce background noise.
When shopping for a PVDM, be sure to take your maximum estimated call density into account, as PVDM3 units come in several sizes, ranging from PVDM3-16 all the way to PVDM3-256. The numerical suffix of each DSP represents the max number of G.711 voice calls that PVDM3 can support, so you want to be sure to overshoot the number of concurrent calls you expect on your network during peak usage in order to provide optimal service.
PVDM3-32's are compatible with all Cisco 2900 and 3900 series routers - although the number of PVDM slots varies from unit to unit. Cisco 2901 and 2911 units support 2 PVDMs, 2921 and 2951 routers support 3 PVDMs, and 3925 and 3945 routers support 4 PVDMs.
