The second phase of networking ,which occurred in the 1960s ,included three major milestones:software switching, digital transmission ,and satellite deployment,in 1965 ,american telephone and telegraph introduced the first stored program control local switch ,the 1 ees switching system ,with the ues of software control, a family of custom calling services (speed calling,call waiting ,call forwarding and three way calling ,etc ,) was mande possible, the first software program for the 1ees switching system had approximately 100,000 lines of codes, today switches may contain ten million lines of code.

第二阶段是网络化，其发生在20世纪60年代，包括三大里程碑：软件交换，数字传输，卫星的运用，在1965年，美国电话电报介绍第一个存储程序控制区域交换机，第1 ees交换系统中，软控制运用在家庭式的呼叫服务中（快速呼叫，呼叫等待，呼叫转接和三方呼叫等，成为可能，第一个软件程序，为1ees切换系统大约有 10万行代码今日交换系统可能含有1千万行的代码。

This system provide an wieldy and powerful integration platform for testers by integrated with global satellite position system, electronic map system and self-contained testing data collection functions. It can shorten the testing implementation cycle and reduce the costs.

该系统将全球卫星定位系统、电子地图系统以及完备的测试功能模块集成在一个便携的移动终端中，为测试人员提供了一个易于使用、功能强大的集成测试数据采集平台，缩短了测试实施周期，减少了测试成本。

The advanced and practicability of Global Position System, and its characteristic orientating exactly has be

全球定位系统的先进性和实用性，其精确定位的功能特点已在各行各业中得到迅速的推广和应用，另一方面，传统的、功能单一的通信技术手段，已经不能适应多种业务发展的需要，因此，从运用先进的全球卫星定位与计算机技术，利用通信系统、多种先进技术集成以及实用性等方面设计集成综合信息系统很有必要。
