电力程控交换机NO.1与NO.7信令转接方式的分析

Analysis of transfer mode between No.1 and No.7 signaling in PBX electrical private network

针对目前电力专网语音交换汇接局存在的中继转接问题,重点分析讨论了2种常用信令的转换方式,即NO.7信令方式TUP消息至NO.1信令方式的配合转换,以及NO.1信令至NO.7信令的配合转换,并以电力专网内广泛运行的Harris20-20机型为例,论述了对其软件的设置方法及注意事项。

Aim at the existent PBX repeaters transfer problem in electrical private network, i.e. some signaling need to be transferred from one mode to another, this paper analyzes two signaling transfer modes in common use, one is to transform No. 7 signaling TUP message into No. 1 signaling and another is to transform No. 1 signaling into No. 7 signaling. Taking Harris 20-20 switch as an example, this paper describes the software configurations and points for attention.
