CISCO Pvdm4 32-channel To 64-channel Factory PVDM4-32U64

Manufacture # Cisco | Model # PVDM4-32U64

The Cisco Packet Voice Digital Signal Processor Modules (PVDMs) enable Cisco 4000 Series Integrated Services Routers (ISRs) to provide rich-media capabilities such as high-density voice connectivity, conferencing, transcoding, media optimization, transrating, and secure voice for Cisco Unified Communications solutions. These new modules support unprecedented scale while allowing for a smaller solution footprint than ever before.
 

Features:

• One of the primary uses of PVDMs is to packetize digital voice into IP packets 
• To enable time-division multiplexing (TDM) digital voice applications
• PVDM modules support ad hoc and meet-me conferencing with various codecs in conjunction 
• With Cisco Unified Communications Manager and Cisco Unified Communications Manager Express
• In conjunction with Cisco IOS® Software, the PVDMs support universal transcoding
• Which allows conversion from any supported codec to any other supported codec
• The PVDMs support transrating, in which the same codec is repacketized in order
• To connect dissimilar networks that have different codec packetization periods
• The PVDMs perform compression, voice-activity detection, jitter management, and echo cancellation
• The echo cancellation offered in the PVDMs has a tail length of 128 milliseconds and complies with ITU-T G.168
• The motherboard PVDMs (PVDM4s) offer multiple power-saving modes, including a power-saver mode when the module is not in use
• In power-saver mode, each PVDM4 can save up to 5 watts of power
