電信基本建設(shè)中涉及國防安全的 ， 應(yīng)執(zhí)行 原信息產(chǎn)業(yè) 部 頒發(fā)的《電信基本建設(shè)貫徹國防要求技術(shù)規(guī)定》。未取得 工業(yè)和信息化部 頒發(fā)的電信設(shè)備入網(wǎng)許可證的設(shè)備不得在工程中使用。 在執(zhí)行本規(guī)范與國家 相關(guān)標(biāo)準(zhǔn)和規(guī)范 有矛盾時，應(yīng)以國家 標(biāo)準(zhǔn)和規(guī)范 為準(zhǔn)。 2 2 術(shù)語和符號 英文縮寫 英文全稱 中文名稱 ADM Add and Drop Multiplexer 分插復(fù)用器 AIS Alarm Indication Signal 告警指示信號 APC Angle Plane
