我局使用的市话906型纵横制交换机,是一种用户小交换设备,无长途性能。为使我局的长途半全自动电路的开通,增加了长途入中继架,以配合906与长机DD14设备完成长途半全自动来话工作。此中继架是为905型机设计制作的。在906机上使用,厂家也只是让我局试用。为此,我们根据随机附的资料进行安装后,出现了插入不可靠,强拆性能不彻底等现象进行了一些技术处理。原电路见附图中实线所示。
I use the local telephone market 906 crossbar switch system is a small user switching equipment, no long-distance performance. To enable the opening of our bureau’s long-distance semi-automatic circuit, added a long-distance into the relay rack to complete long-distance semi-automatic call to work with 906 and long machine DD14 equipment. This trunking is designed for the 905 machine. Used on the 906 machine, manufacturers just let me Bureau trial. To this end, we based on the information attached to the installation, there has been unreliable insertion, demolition demolition performance is not complete and so on some technical processing. The original circuit shown in solid line in the figure.
