Abstract

A high-speed channel switching control system that uses T-S-T three-stage switching to control high-speed switching of time-division multiplex communication in a multi-processor type electronic exchange system, including multiple groups of first switches (11-1n) using the time-division switching method, using high-speed channel The second switch (21-2n) of switching method, the 3rd switch (31-3n) of time-division switching method and the processor (41-4n) that are used to control each switch, use two processors ( 41-4n) jointly obtain the idle time slot information on the interconnection switch and determine the time slot used in the connection, so as to control the connection of the required switch.

Description

technical field [0001] The present invention relates to the control method and control system of the time-division switch in the electronic exchange system, in particular to the T-S-T three-stage switching time-division multiplex communication high-speed switching control system and control method in the multi-processor type electronic exchange system. Background technique [0002] Generally, in order to distribute the load, it is a conventional method to use each processor in a multi-processor type electronic switch to process a plurality of predetermined number of registered terminals. And when adopting this kind of multi-processor type electronic switch and needing a large amount of switching, then adopt the time-division switching method with T-S-T three-level switching, promptly use the corresponding processor that a plurality of dispersively provide to control a plurality of dispersively provided first respectively One T stage and a third T stage, while a single proces...
