Cisco PVDM2-32 Overview:
The Cisco PVDM2-32 is a digital signal processor (DSP) module designed for Cisco Integrated Services Routers (ISRs) to enable voice processing capabilities. It is part of the Cisco Packet Voice Digital Signal Processor Module (PVDM) family and offers a total of 32 channels for voice processing.
Here’s an overview of the Cisco PVDM2-32 module:
- Voice Processing: The PVDM2-32 is equipped with DSPs that enable voice compression, decompression, echo cancellation, and other voice processing functions. These capabilities ensure high-quality voice communication over IP networks.
- Channel Capacity: The PVDM2-32 module provides 32 channels, allowing for voice calls, conferencing, transcoding, and other voice-related tasks.
- Compatibility: This module is compatible with various Cisco ISR platforms, including the Cisco 2800, 2900, 3800, and 3900 Series routers. It can be easily installed in the PVDM slot of these routers.
- Voice Codec Support: The PVDM2-32 supports multiple voice codecs, such as G.711, G.729a, G.729ab, G.723.1, G.726, G.728, G.722, and iLBC. These codecs determine the compression and encoding standards for voice transmission.
- Integrated Services: The PVDM2-32 integrates seamlessly with other Cisco services and applications, such as Cisco Unified Communications Manager (CUCM) and Cisco Unified Border Element (CUBE). This integration enables advanced voice features and collaboration services.
- Redundancy and Resilience: The PVDM2-32 supports redundancy features, allowing for the configuration of backup DSP resources. This ensures uninterrupted voice services in case of module failure or system maintenance.
- Power Requirements: The PVDM2-32 module operates at +5V DC and typically draws around 2A of current.
