浅谈通信系统中PCM常见故障处理

On the Communication System PCM Common Fault Handling

PCM设备是电力通信网中重要的接入设备,在电力调度通信自动化系统中起着重要的作用。PCM(Pulse Code Modulation,脉冲编码调制)终端复用设备是完成单路信号和多路信号(这里指2Mbit/s信号)的复接、分接设备,也是实现A/D转换不可缺少的设备,因其具有规范和灵活的接口、智能化程度高等特点,成为电力通信网的重要组成部分。本文着重介绍PCM的常见故障处理。

PCM device is an important electric power communication network access equipment,power dispatching automation system communication plays an important role.PCM(Pulse Code Modulation,Pulse Code Modulation)terminal multiplexer is the completion of a single-channel signal and multi- channel signal(in this case 2Mbit/s signal)of the multiplexer,tap equipment,but also achieve the A/D conversion is not a lack of equipment,because of its norms and flexible interfaces,and high degree of intelligence has become a major electric power communication network components.This article focuses on the common PCM fault handling.
