Audio/Video Command & Dispatch System

1. Introduction

The IDM Multimedia Dispatch Switch MSAP-CP is a PBX/IPPBX-based converged communication equipment developed and designed by Beijing Ruiguang Jiyuan Digital Technology Co., Ltd. It is widely applied and meticulously crafted for telecom operators, government agencies, industries, and large/medium-sized enterprise users, delivering powerful functionality. The product is designed using advanced digital integrated circuits, highly integrated optimized structures, SDH/PDH optical transmission technology, and PBX/IPPBX communication technology. It can be deployed on the enterprise side or in carrier equipment rooms, providing users with a comprehensive integrated audio/video convergence solution.

The system adopts a modular design with a card-slot assembly approach, integrating traditional TDM PBX switch E1 trunk access and analog extension user functions. It supports various signaling methods including PRI, NO.1, NO.7, and SIP/H.323, and can connect to traditional PSTN networks and carrier VoIP softswitch platforms. It enables voice, fax, and data transmission over both TDM and IP networks, achieving secure and efficient enterprise internal audio/video converged communications.

The IDM Multimedia Dispatch Switch MSAP-CP integrates SDH optical transmission, E1 access, various 64K Z-interfaces, IP communications, and various wireless communication access methods into one platform, providing multimedia communication services including video, audio, fax, and data.

The IDM Multimedia Dispatch Switch MSAP-CP is built on a multi-bus system incorporating Telecom BUS, IP bus, and ST-BUS bus architectures, supporting digital trunk, IP trunk, and analog trunk modes. It can simultaneously connect multiple touchscreen integrated Dispatch Consoles. It also supports seamless integration with voice recording/voicemail servers, network management servers, fax/SMS/email servers, audio/video recording servers, GIS servers, and GPS/GPRS servers.
