PVDM4-64-RF

64-channel DSP module REMANUFACTURED

PVDM4-64-RF is a professionally remanufactured Cisco Fourth-Generation Packet Voice and Data Module (PVDM4) with 64-channel DSP capacity, designed to provide digital signal processing for voice, video, and conferencing workloads on Cisco ISR G2 and ISR 4000 series routers. This module enables high-density voice termination and media processing directly on the router, eliminating the need for external DSP resources in unified communications deployments.

This remanufactured DSP module meets Cisco OEM specifications and has been thoroughly inspected and tested prior to shipment. Validation includes DSP channel capacity verification across all 64 channels, firmware integrity and compatibility testing with supported IOS and IOS XE versions, and physical connector and slot interface inspection for proper seating and signal integrity.

Key Features:
• 64-channel DSP capacity for high-density voice and media processing
• Supports G.711, G.722, G.728, G.729, and iLBC voice codecs
• Compatible with Cisco ISR G2 (2900/3900) and ISR 4000 series platforms
• Enables hardware-based conferencing, transcoding, and MTP functions
• Supports T.38 fax relay and modem passthrough for legacy device integration
• Fourth-generation PVDM architecture with improved density over PVDM3
