时分脉码交换是当前交换技术发展的主要方向,由时分脉码交换组成的数字通信网可以做到两个综合,即交换和传输的综合,以及通话和各种其他如数传等业务的综合.时分脉码交换的基本接续单元是T型时分接线器,它可以单独使用以组成无阻塞的小容量时分接续网,也可以和S型时分接线器一起组成大型数字交换网.本文准备以一个T型时分接线器单独使用为例,说明T型时分接线器的电路组成,具体实现以及交换接续原理.
The time-division pulse code exchange is the main direction of the development of the current exchange technology. The digital communication network formed by the time-division pulse code exchange can do two synthesis, that is, the combination of exchange and transmission, and the integration of the call and various other services such as data transmission The basic connection unit of the time-division pulse-width modulation is the T-type time division switch, which can be used alone to form a non-blocking small-capacity time-division continuous network, and can also be combined with the S-type time division switch to form a large digital switching network. T-type time-division switch alone as an example to illustrate the T-type time-switch circuit components, the specific realization and exchange connection principle.
