Synchronous processing method, synchronous processing system for centralized type voice and voice communication processing equipment

Abstract

The invention provides a synchronous processing method and a synchronous processing system for centralized type voice and voice communication processing equipment; wherein the method comprises the following steps: selecting command according to a datum clock, selecting one reference clock out of the multiple reference clocks as the reference clock; carrying out corresponding clock synchronizationprocessing on the datum clock according to different voice modules of multiple voice modules to generate synchronous clock signals of corresponding voice modules; carrying out corresponding frame synchronization processing on the datum clock according to different voice modules to generate frame synchronization signals of corresponding voice modules; returning the multiple synchronous clock signals and the frame synchronization signals respectively to corresponding voice modules. In the invention, a datum clock is selected from multiple reference clocks as the datum clock, then clock synchronization and frame synchronization processing is carried out with the datum clock as the basis, so as to realize the frame synchronization signals based on the system datum clock; in addition, adjustment of frame synchronization signals are more flexible, thus better meeting requirements of the voice modules on complicated timing sequence.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a centralized voice synchronous processing method, system and voice communication processing equipment. Background technique [0002] The centralized voice system is proposed relative to the traditional distributed voice system. Its purpose is to use the voice channel switching technology to switch the multiple voice channels between the voice modules, so as to reduce the number of voice modules and reduce the system cost. The cost of the equipment. Usually, in order to keep the data between multiple voice modules in the centralized voice system to be transmitted synchronously, to ensure that the voice module at the receiving end can accurately receive each voice data sent by the voice module at the sending end without data loss , the centralized voice system will use time division multiplexer and multiplexer (Time Division Multiplex and Multiplexer, referred to as...
