澳大利亚99％的电话用户已经纳入全国自动电话网,1983年上半年又有10000个电话用户实现了自动化,其目的是要在1990年前实现全国电话自动化。目前全国大约还有35500门靠人工接续的电话需要进行技术改造,而其中大部份处于边远的农村地区,实现技术改造并接入全国网路困难很多,而且投资费用很大。这一规划的投资,从1983年到1990年估计需要2.5亿澳元。为把先进的数字传输技术应用于边远地区,拟采用一种数字无线电集中器系统(DRCS),此系统可在1984年投入较边远的农村地区使用。每个系统可以收容120个用户,到交换机的最大距离为600km。大约有6000个农村用户计划采用这种系统来满足通信需要。
Ninety-nine percent of Australia’s telephone subscribers have been integrated into the national automatic telephone network and an additional 10,000 subscribers were automated in the first half of 1983, aiming to automate national telephones by 1990. At present, there are still about 35,500 hand-held telephones nationwide that require technological transformation, most of which are in remote rural areas. It is much more difficult to achieve technological transformation and access to the national network, and the investment is very expensive. Investment in this program is estimated at A $ 250 million from 1983 to 1990. In order to apply advanced digital transmission technology to remote areas, it is proposed to adopt a digital radio concentrator system (DRCS) which could be put into use in more remote rural areas in 1984. Each system can accommodate 120 users, the maximum distance to the switch is 600km. Some 6,000 rural users plan to use this system to meet their communications needs.
