在目前的技术条件下建立一个有线电视网络系统比较简单,但是要维护管理好一个有线电视网络使广大有线电视用户收看好众多的电视节目并非一件易事。特别是一些乡镇的有线电视网络,在建网初期资金较紧张,设备档次较低,给今后的网络维护带来了技术上的一些麻烦,现在要一下子提高设备档次又苦于缺乏资金;因此网络的维护、排障与用户的收看效果往往会出现一些矛盾。针对上述情况我们从十几年的安装、调试有线电视网络系统的实践中端呈一点有关有线电视网络调试、维修的体会。
Under the current technical conditions, it is relatively simple to set up a cable television network system. However, it is not easy to maintain and manage a cable television network so that a large number of cable television users can enjoy many television programs. In particular, the cable television network in some villages and towns has a relatively tight fund and low equipment grade in the initial stage of network construction, which brings some technical troubles to network maintenance in the future. Now it is time to raise the grade of equipment and suffer from lack of funds. Therefore, The maintenance, troubleshooting and the user’s viewing often appear some contradictory. In response to the above situation from more than 10 years of installation, commissioning of cable television network system in the end a bit about the cable network debugging, maintenance experience.
