目前我国引进不少程序控制自动电话用户小交换机,其厂家、型号不尽相同且容量也小到几十门大到几千门,这些程控用户小交换机大多只有故障可见警报(用发光二极管显示),没有故障可闻警报,对机务技术维护管理带来一定的不便。程控用户小交换机除了话务员外大多不昼夜值班管理,没有故障可闻警报就很难即时发现问题,及早处理障碍、保证通讯不间断。为此我们试制了非常简便、经济、有效的(大小)故障可闻警报器,可供程控用户小交换机技务管理人员参考。
At present, China introduced a lot of programs to control the automatic telephone subscriber small exchangers, its manufacturers, models are not the same and the size is as small as several dozens to thousands of doors, these program-controlled users are mostly only the small switches visible alarm (with light-emitting diode display) , There is no fault audible alarm, the maintenance of maintenance maintenance technology has brought some inconvenience. Program-controlled users of small switches in addition to the attendant mostly outside the day and night on duty management, there is no fault can be audible alarm is difficult to find problems immediately, early handling of obstacles to ensure uninterrupted communications. To this end, we have trial-produced a very simple, economical, effective (size) fault audible alarm, which can be used as a reference for small switch operator of program-controlled users.
