Product Review

The Cisco PVDM4-64 offers a high density of voice and video channels, supporting up to 64 low complexity channels and 32 high complexity channels, catering to diverse networking needs. However, its performance and capabilities, such as echo cancellation with a tail length of 128 ms and comprehensive jitter management, are contingent on the specific Cisco IOS version and hardware it is paired with, potentially limiting flexibility. Additionally, while it boasts power-saving modes and a wide operating temperature range, its power consumption of 4.85 W and reliance on specific interface slots may restrict its use in varied networking environments.


The Cisco PVDM4-64 is a high-density voice and video DSP module designed to enhance the capabilities of Cisco's Integrated Services Routers (ISRs). This module provides 64 channels for voice and video processing, making it an essential component for businesses looking to optimize their voice and video communications infrastructure. Key specifications of the Cisco PVDM4-64 include its ability to handle 64 low complexity channels, 48 medium complexity channels, and 32 high complexity channels. This flexibility allows it to support various codecs and media processing functions, adapting to the needs of different communication environments. The module is powered by Cisco IOS software, ensuring seamless integration and reliable performance within Cisco networking ecosystems. The PVDM4-64 is designed with power efficiency in mind, featuring power-saving modes that reduce energy consumption when the module is not in full use. It boasts a tail length of echo cancellation of 128 ms, significantly improving call quality by reducing echo and noise in voice communications. The module interfaces with the Integrated Services Card Slot on the motherboard or through a T1/E1 Network Interface Module (NIM), providing versatile connectivity options. With a voltage rating of 3.3 V and power consumption of 4.85 W, the PVDM4-64 is engineered for efficiency. Its compact dimensions, with a height of 0.67 inches, a width of 2.50 inches, and a depth of 2.62 inches, allow for easy installation without occupying excessive space within the router chassis. Safety and regulatory compliance are paramount for Cisco products, and the PVDM4-64 meets several international standards, including IEC 60950, AS/NZS 60950-1, CAN/CSA-C22.2 No. 60950-1, GB4943-95, and EN60950-1. This ensures that the module is safe for use in various environments around the globe. The PVDM4-64 also includes several key functions to enhance voice and video communications: - Compression: Reduces bandwidth usage without compromising quality. - Voice Activity Detection: Optimizes bandwidth by transmitting voice data only when necessary. - Jitter Management: Ensures smooth voice and video transmission by compensating for variations in packet arrival times. - Echo Cancellation: Eliminates echo for clearer voice communication. Compatibility and compliance vary based on the platform and system configuration, with homologation and Mean Time Between Failures (MTBF) being system-dependent. The module adheres to stringent emissions standards, including CISPR22, EN55022, and CFR47, ensuring minimal interference with other electronic devices. Additional standards compliance includes EN61000-3-3 for flicker and EN61000-3-2 for harmonics, further demonstrating the module's commitment to quality and environmental responsibility. In summary, the Cisco PVDM4-64 is a versatile and efficient solution for businesses looking to expand or enhance their voice and video communication capabilities. Its wide range of features, combined with Cisco's reliability and support, make it an essential component for modern communication networks.
