本文介绍 Tellabs 6008A FXS 至 E＆M 线信令变换器的功能、工作原理以及主要的技术参数;并着重介绍该信令变换器在 CVSD/PSK/SCP C/PA 卫星通信网路中取代 Tellabs 6006信令变换器,以实现话音自动接续功能的操作使用方法。这种信令变换器可在地球站与交换机之间采取用户线接口情况下的SCPC/PA 卫星通信网中完成各卫星通信地球站用户之间的电话直拨业务,且价格低廉,安装及操作使用较为简便。
This paper introduces the functions, working principle and main technical parameters of Tellabs 6008A FXS to E & M line signaling converter. It also introduces the signaling converter to replace Tellabs 6006 signaling in the CVSD / PSK / SCP C / PA satellite communication network Converter, in order to achieve the voice of the automatic operation of the connection function. This signaling converter enables direct telephone dialing between subscribers of earth stations in satellite communications in the SCPC / PA satellite communications network with a subscriber line interface between the earth station and the switch and is inexpensive and easy to install and operate More convenient.
