Audio/Video Command & Dispatch System

1. Introduction

The IDM Multimedia Dispatch Switch MSAP-CP is a PBX/IPPBX converged communication device developed and designed by Beijing Raytrans Digital Technology Co., Ltd. It is widely used by telecom operators, government, industry, and large/medium-sized enterprises. The product adopts advanced digital integrated circuits, highly integrated optimized structure, SDH/PDH optical transmission technology, and PBX/IPPBX communication technology. It can be deployed on the enterprise side or in the operator's equipment room, providing users with an integrated audio/video converged comprehensive solution.

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

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

The IDM Multimedia Dispatch Switch MSAP-CP is based on Telecom BUS, IP BUS, and ST-BUS multi-bus architecture, supporting digital trunk, IP trunk, and analog trunk modes, while allowing connection of multiple touchscreen integrated Dispatch Consoles. It also supports seamless connection with voice recording/voicemail servers, network management servers, fax/SMS/email servers, recording/video recording servers, GIS servers, GPS/GPRS servers, etc.
