Cisco PVDM4-64 DSP Module

Cisco PVDM4-64 DSP Overview

The PVDM4-64 is a Digital Signal Processor (DSP) module designed for Cisco ISR (Integrated Services Router) platforms. It provides voice services, including transcoding, conferencing, and media termination, for voice-over-IP (VoIP) applications. This module is part of the PVDM4 series and is specifically designed for platforms such as the Cisco 4000 Series ISRs, offering high-density voice capabilities.

Features and Benefits :

• DSP Capacity:
  • Provides 64 voice channels.
  • Supports a wide variety of codecs, including G.711, G.729, and G.722, for high-quality voice compression.
  • Scalable solution to accommodate future voice service expansions.
• Applications:
  • Transcoding: Converts between different voice codecs (e.g., G.711 to G.729) to allow communication between different endpoints.
  • Voice Conferencing: Supports audio conferencing for multiple parties.
  • Media Termination: Provides media termination points for VoIP calls, enabling services like call progress tones and announcements.
  • Voice Termination: Enables the termination of voice calls for digital TDM circuits in VoIP networks.
• Power Efficiency:
  • Lower power consumption compared to previous generations (PVDM3), providing higher performance per watt.
• Scalability:
  • Can be combined with other PVDM4 modules to scale up the number of voice channels. For example, multiple modules can be installed to meet higher density voice requirements.
• Enhanced Features:
  • Supports features such as Secure Real-Time Transport Protocol (SRTP) for secure voice communications.
  • Facilitates integration of Unified Communications (UC) services such as call routing, voicemail, and IP-based telephony.
• Platform Compatibility:
  • Compatible with Cisco ISR 4000 Series routers, including models such as the ISR 4321, ISR 4331, and ISR 4351.
  • Can also be used in the Cisco 2900 and 3900 Series ISRs with appropriate firmware and IOS versions.
• Flexibility in Deployment:
  • Enables voice connectivity in both IP and traditional telephony environments, supporting features like transcoding and conferencing within the same module.
• Firmware and Software:
  • Requires Cisco IOS software to manage the voice features and to configure the DSP module for different services like voice transcoding or conferencing.
