電話交換機的主要任務(wù)是實現(xiàn)用戶間通話的接續(xù)?；緞澐譃閮纱蟛糠郑涸捖吩O(shè)備和控制設(shè)備。話路設(shè)備主要包括各種接口電路(如用戶線接口和中繼線接口電路等)和交換 (或接續(xù))網(wǎng)絡(luò)；控制設(shè)備在縱橫制交換機中主要包括標(biāo)志器與記發(fā)器，而在程控交換機中，控制設(shè)備則為電子計算機，包括處理器(CPU),存儲器和輸入 /輸出設(shè)備。
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.
安裝電話交換機的時候要考慮公司或者機構(gòu)準(zhǔn)備怎樣的運行系統(tǒng)。安裝就緒的廣州電話交換機是為以非威脅方式對魚貫而入的訪問提供一種計量和審計的方法。在這些選擇中存在著某種程度的偏執(zhí)狂，電話交換機的終功能可能將是行政上的結(jié)果，而非工程上的決策。
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.
電話交換機需要監(jiān)控到什么程度，控制到什么水平也是必須要考慮的。你開始時先列出你的總體目標(biāo)，然后把需求分析與風(fēng)險評估結(jié)合在一起，挑出與風(fēng)險始終對立的需求，加入到計劃完成的工作的清單中。是否設(shè)置像過濾器這樣的屏蔽路由器，是否將暴露的簡易機放置在外部網(wǎng)絡(luò)上為telnet、ftp、news等運行代理服務(wù)，允許與一臺或多臺內(nèi)部計算機的通信。這兩種方式都存在著優(yōu)缺點，代理機可以提供更高水平的審計和潛在的性，但代價是配置費用的增加，以及可能提供的服務(wù)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.
