for P/N: C1-CISCO4331/K9, ISR4331-AXV/K9, ISR4331-V/K9, ISR4331-V/K9-RF, ISR4331-VSEC/K9
Overview
The Cisco Fourth-Generation Packet Voice Digital Signal Processor Module (PVDM4) enables Integrated Services Routers (ISRs) to provide rich-media capabilities such as high-density voice connectivity, conferencing, transcoding, media optimization, transrating, and secure voice.
Conferencing, transcoding, and transrating services
Voice-quality management
Energy-saving feature
Conferencing, transcoding, and transrating servicesThe PVDM4 modules support digital voice connections, conferencing, and universal transcoding services. The PVDM4 modules support transrating, where repacketization of the same codec is used to connect dissimilar networks that have different codec packetization periods.Voice-quality managementThe PVDM4 modules perform compression, voice-activity-detection, jitter-management, and echo-cancelation functions.Energy-saving featureThe PVDM4 DSPs offer multiple power-saving modes, including a power-saver mode when the module is not in use.
