随着我省电力系统专用数字通信网的形成,电力专用时分程控交换网已经成为全国电力专用通信网的重要组成部分。通信网的重要功能之一,即综合业务数字网(以下简写为ISDN)自然提到了议事日程。ISDN是通过通信网络,为用户提供数据、图像、传真、话音等。使用通常的一对话音软线,接入不同用途终端设备,利用ISDN网络接口设备(2B+D),提供一个19.2kbps的数据口,就达到数据传输的目的,又不影响正常通话。这样就克服了现行的用调制解调器、把数据变换
With the formation of the power system digital communication network in our province, the power-specific time-division program-controlled switching network has become an important part of the national power-dedicated communication network. One of the important functions of the communication network, namely Integrated Services Digital Network (hereinafter referred to as ISDN) naturally refers to the agenda. ISDN is through the communication network, to provide users with data, images, fax, voice and so on. Use the usual pair of voice cord, access terminals for different purposes, the use of ISDN network interface device (2B + D), to provide a 19.2kbps data port, to achieve the purpose of data transmission, without affecting the normal call. This overcame the current use of modems to transform the data
