电话交换机的主要任务是实现用户间通话的接续。基本划分为两大部分：话路设备和控制设备。话路设备主要包括各种接口电路(如用户线接口和中继线接口电路等)和交换 (或接续)网络；控制设备在纵横制交换机中主要包括标志器与记发器，而在程控交换机中，控制设备则为电子计算机，包括中央处理器(CPU),存储器和输入 /输出设备。
The main task of telephone exchanges is to connect calls between users. Basically divided into two parts: speech equipment and control equipment. Telephone circuit equipment mainly includes various interface circuits (such as user line interface and relay line interface circuit etc.) and switching (or relay) networks; control devices mainly include markers and registers in crossbar switches, while in SPC switches, control devices are electronic computing machines, including central processing (CPU), memory and input. / output equipment.
安装电话交换机的时候要考虑公司或者机构准备怎样的运行系统。安装就绪的广州电话交换机是为以非威胁方式对鱼贯而入的访问提供一种计量和审计的方法。在这些选择中存在着某种程度的偏执狂，电话交换机的最终功能可能将是行政上的结果，而非工程上的决策。
When installing a telephone switchboard, consider what kind of operation system the company or organization will prepare. The installed Guangzhou telephone exchange provides a means of measurement and audit for non threatening access to incoming fish. There is a certain degree of paranoia in these choices, and the final function of telephone exchanges may be administrative rather than engineering decisions.
电话交换机需要监控到什么程度，控制到什么水平也是必须要考虑的。你开始时先列出你的总体目标，然后把需求分析与风险评估结合在一起，挑出与风险始终对立的需求，加入到计划完成的工作的清单中。是否设置像过滤器这样的屏蔽路由器，是否将暴露的简易机放置在外部网络上为telnet、ftp、news等运行代理服务，允许与一台或多台内部计算机的通信。这两种方式都存在着优缺点，代理机可以提供更高水平的审计和潜在的安全性，但代价是配置费用的增加，以及可能提供的服务水平的降低。
Telephone exchanges need to be monitored to what extent they must be considered. You start with a list of your overall goals, then combine the needs analysis with the risk assessment, pick out the needs that are always opposed to the risk, and add to the list of the planned work. Whether a shielding router such as a filter is set up, or whether the exposed improver is placed on the external network for Telnet, FTP, news and other running agent services, allowing communication with one or more internal computers. There are advantages and disadvantages of these two ways. The agent can provide higher level of audit and potential security, but the cost is the increase of the cost of configuration, and the reduced level of service that may be provided.
