64-channel DSP module REMANUFACTURED

Inventory quantities are subject to availability and are not guaranteed until the order is placed.

The PVDM4-64-RF is a professionally remanufactured Cisco PVDM4-64 fourth-generation packet voice and fax DSP module supporting up to 64 channels for Cisco ISR G2 and 4000 Series integrated services routers. This DSP module enables hardware-accelerated voice transcoding, conferencing, and fax relay functions directly on the router, supporting SCCP and SIP media processing for Cisco Unified Communications Manager Express, Cisco Unity Express, and PSTN gateway deployments. PVDM4 modules offer improved density and performance compared to previous PVDM generations.

This remanufactured DSP module meets the same channel capacity and voice processing specifications as a new Cisco PVDM4-64 unit. Each unit has been tested for DSP channel initialization, voice quality performance, and compatibility with supported Cisco ISR platforms.

Key Features:
• 64-channel DSP module supporting hardware voice transcoding and conferencing
• Compatible with Cisco ISR G2 (2900/3900) and ISR 4000 Series routers
• Supports SCCP and SIP media processing for UCM Express deployments
• Hardware fax relay (T.38) support ensuring reliable fax over IP operation
• Fourth-generation PVDM design with improved density over PVDM3 modules
• Enables PSTN gateway, conferencing, and transcoding without external DSP hardware

This refurbished DSP module is ideal for enterprise IT teams and communications integrators deploying Cisco ISR-based voice gateways and UCM Express platforms requiring hardware DSP resources. By choosing a remanufactured Cisco PVDM4-64, you provide DSP-accelerated voice processing capacity at lower hardware cost.
