NIM-PVDM-64 Overview
NIM-PVDM-64 is a high-performance voice processing module designed for integration into modular router platforms. It provides digital signal processing capabilities to support up to 64 concurrent voice channels, enabling efficient deployment in enterprise and service provider networks. Although it does not operate as a standard Ethernet or Wi‑Fi card, its design is optimized for processing voice data rather than high-speed packet switching, making it ideal for voice over IP and telephony applications.
This module features a modular form factor that slots directly into compatible Cisco routers, ensuring seamless installation and integration. While traditional specifications such as connector type and advertised data rates (e.g., 1Gbps or 10Gbps) do not apply, the NIM-PVDM-64 delivers industry-standard operating temperatures and robust performance for digital voice processing. Its compatibility with Cisco networking platforms and support for industry voice protocols help expand call processing capabilities in demanding communication environments.
NIM-PVDM-64 price is $1,954.00, a 51.3% saving from the Cisco list price of $4,011.00. NIM-PVDM-64 is in stock and available for next-day dispatch. (terms applied)
