在設(shè)計(jì)上都支持長久在線功能，這就要求DTU包含了上電自動(dòng)撥號(hào)、采用心跳包保持長久在線（當(dāng)長時(shí)間沒有數(shù)據(jù)通信時(shí)，移動(dòng)網(wǎng)關(guān)將斷開DTU與中心的連接，心跳包就是DTU與數(shù)據(jù)中心在連接被斷開之前發(fā)送一個(gè)小數(shù)據(jù)包，以保持連接不被斷開）、支持?jǐn)嗑€自動(dòng)重連、自動(dòng)重?fù)芴?hào)等特點(diǎn)。支持參數(shù)配置，長久保存 GPRS DTU作為一種通信設(shè)備，其應(yīng)用場合十分廣（guang）泛。在不同的應(yīng)用中，數(shù)據(jù)中心的IP地址及端口號(hào)，串口的波特率等都是不同的。因此，GPRS DTU都應(yīng)支持參數(shù)配置，并且將配置好的參數(shù)保存內(nèi)部的長久存儲(chǔ)器件內(nèi)（一般為FLASH或EEPROM 等）。一旦上電，就自動(dòng)按照設(shè)置好的參數(shù)進(jìn)行工作。 GPRS DTU的擴(kuò)展功能：較為專業(yè)的GPRS DTU還提供一些擴(kuò)展功能，主要包括：支持?jǐn)?shù)據(jù)中心域名解析 </p><div style="width:100%;text-align: center;"><img style="max-width:
