无线电信电话公司(TRT)为法国电气和瓦斯当局研制了移动通信网的一期工程,取名RAMAGE。由19个基地台和600部移动台组成,计划1985年初投入运行,到1990年扩建到拥有600个基地台和15000部移动台。收发报机采用TRT公司的P900系列,交换中心以TRTCOMPAC系列所用的16比特计算机为基础,RAMAGE的运营是全自动的,如动态的信道指定、入网排队、移动台的自动定位等,信令传输在另外信道上进行。服务项目繁多,如5单位参加的电话会议、呼叫转发、遥远振铃、优先等级和多位数储存等。该通信网使用方便、维护容易、不易出现故障。
The Wireless Telecommunications Telephone Company (TRT) has developed the first phase of a mobile communications network for the French electrical and gas authorities named RAMAGE. Composed of 19 base stations and 600 mobile stations, it is planned to be operational in early 1985 and expanded to have 600 base stations and 15,000 mobile stations by 1990. Transceivers use TRT P900 series, the switching center to TRTCOMPAC series of 16-bit computer-based, RAMAGE operation is fully automatic, such as dynamic channel assignment, network queuing, mobile station automatic positioning, signaling transmission In another channel. A wide range of services, such as 5 units to participate in the conference call, call forwarding, remote ringing, priority and multi-digit storage. The communication network easy to use, easy to maintain, not prone to failure.
