Dialogic DMV2400A-CPCI Digital Media Processing Board Card

Multi-channel Voice Processing Capability: Supports concurrent processing of up to 240 voice channels, meeting the high-density communication needs of large call centers or telecom systems to simultaneously handle hundreds of phone calls, voice conferences, or fax transmissions.

Support for Multiple Coding Formats: Compatible with various voice coding standards such as G.711, G.729, G.723.1, etc., automatically switching coding formats based on network bandwidth and sound quality requirements to ensure clear and efficient voice transmission.

Flexible Signal Processing Functions: Supports technologies such as echo cancellation, noise suppression, and Voice Activity Detection (VAD) to enhance voice communication quality; also has functions like DTMF signal detection/generation and Caller ID processing.

Conference Bridging and Mixing Capability: Built-in conference bridging engine enables creating multi-user voice conferences, supporting dynamic adjustment of conference member quantity and permissions, suitable for multi-party calling scenarios in telephone conference systems or call centers.

High Availability and Fault Tolerance Design: Supports hot-swapping to replace the board without interrupting system operation; features redundant power supplies and fault detection mechanisms to reduce service interruptions caused by hardware failures.

Open APIs and Compatibility: Provides Dialogic standard APIs (such as HMP, EDK) for developers to integrate into custom communication systems, compatible with mainstream operating systems (e.g., Linux, Windows) and communication platforms (e.g., Asterisk, Genesys).

Receives digital voice signals (PCM format) from the telecom network via T1/E1 interfaces, or VoIP data packets (such as RTP format) via IP interfaces.

The DSP chip on the board decodes the signals into processable raw voice data.

Performs preprocessing such as noise reduction and echo cancellation on voice data to improve sound quality; selects coding formats (such as G.729 compression) based on configuration to reduce data transmission volume.

Supports real-time voice processing, such as interface calls for Text-to-Speech (TTS) and Automatic Speech Recognition (ASR) (requires software collaboration).

When processing multi-party conferences, the board's conference bridging module mixes multiple voice signals to generate conference audio streams and routes them to each participant.

Supports call routing control based on software instructions, such as transfer, hang up, hold, and other operations.

Encodes the processed voice signals into target formats (such as PCM or VoIP data packets) and sends them to target devices (such as switches, IP phones) via corresponding interfaces.
