随着交换和传输技术的新发展,利用自动交换路由原理的全国用电话自动拨号的计划正在顺利地建立中。 当此计划完成之后,对维护工作的要求将更加严格,这是由于互通联结的线路的可能数量将增多,同时话务员对大部分通话不能进行检查。为满足长途干线电路维护工作的需要,干线电路自动检测及传输测量设备已经建立。 这些设备能够对长途干线的工作情况进行自动检测,并进行传输测量。通过遥控记录器在测试端进行记录。 本文描述了上述装置的一般特征,详细介绍了工作测试设备及传输设备。
With the new developments in switching and transmission technologies, plans for automatic telephone dialing nationwide using automatic exchange routing principles are well underway. When this program is completed, the need for maintenance will be stricter, as the number of interconnected lines will increase, and the attendant will not be able to check most calls. In order to meet the needs of long-distance trunk circuit maintenance, trunk circuit automatic detection and transmission measurement equipment has been established. These devices are able to automate the detection of long-haul trunk lines and make transmission measurements. Through the remote recorder in the test side of the record. This article describes the general characteristics of the device described above, details of the work of test equipment and transmission equipment.
