Voice communication control system based on TDM and IP buses

Abstract

The invention discloses a voice communication control system based on TDM and IP buses, comprising an IP telephone, a voice communication panel, a network management terminal, an external IP network, an MPU unit, a magnet interface, an EM interface, an FXO interface and an FXS interface. The IP telephone, the voice communication panel, the network management terminal and the external IP network are on the IP side, and are connected with the MPU unit through an IP bus. The magnet interface, the EM interface, the FXO interface and the FXS interface are on the TDM side, and are connected with the MPU unit through a TDM bus. The voice communication panel is a communication terminal. The network management terminal is used for monitoring and managing the system. The external IP network is used for realizing external connection of the system. The magnet interface, the EM interface, the FXO interface and the FXS interface are analog user interfaces based on the TDM bus.

Description

technical field [0001] The invention belongs to the technical field of voice communication, and in particular relates to a voice communication control system based on TDM and IP dual buses for the interaction and conversion of TDM bus, IP bus signaling information and media information. Background technique [0002] The voice communication control system is an important part of large-scale automatic command and control systems such as military and civil aviation control and military command and control. At present, there are related products of two technical systems on the market. One is the traditional one that uses TDM as the bus and circuit switching as the core. The voice communication control system; the second is a voice communication control system based on commercial server architecture and IP soft switch as the core. The products of the two technical systems have their own advantages and disadvantages. The former is widely used because of its advantages such as high...

Problems solved by technology

The products of the two technical systems have their own advantages and disadvantages. The former is widely used because of its advantages such as high voice quality, strong real-time processing, small delay, strong network switching and conference bridge capabilities, but there is also a signal transmission distance. However, due to the use of commercial servers as the platform and the implementation of pure softswitching, although its network capabilities have been improved, it still has processing capabilities, especially media switching capabilities, conference bridges, etc. Capabilities and media processing implementation capabilities are limited by its hardware platform and cannot meet the requirements of the large-capacity command and control system in terms of the number of interfaces, multi-function (especially the ground-air conference function), real-time performance, etc.
