Questions & Answers
What is a PVDM Voice/Fax Module?
A PVDM (Packet Voice Digital Signal Processor Module) is a Cisco hardware component that provides DSP resources for voice and fax processing on integrated routers, enabling features such as voice compression, echo cancellation, and T.38 fax relay.
How do PVDM modules support voice and fax on Cisco routers?
PVDM modules allocate dedicated DSP channels for encoding/decoding voice codecs and fax relay, ensuring real-time processing of VoIP calls and T.38 fax transmissions with minimal latency and high reliability.
What are the differences between PVDM2, PVDM3, and PVDM4?
PVDM2, PVDM3, and PVDM4 differ in DSP density and processing power: PVDM2 offers up to 16 channels, PVDM3 up to 240 channels, and PVDM4 up to 512 channels per module, supporting higher call volumes and advanced codecs.
How many concurrent calls can a PVDM4-64 module handle?
A PVDM4-64 supports up to 64 G.711 calls or equivalent mixed-codec sessions, providing scalable DSP resources for medium-sized deployments requiring voice and fax capabilities.
