analog code
解釋
模擬編碼-
Digital speech has preponderance over analog speech in reliability, robustness and security during communication. however, digital speech needs more bandwidth than the analog signal. especially with the requirement for communication frequency increasing, it ' s necessary to code speech signal at low rates
但是，數字化后的信號所佔的頻帶大幅增加，特別是在帶寬需求日益增長的今天，這個問題尤為突出，因此語音的低速率編碼（即壓縮編碼）成為迫切的要求。 -
It can provide many functions : the conversion between transfer formats, the conversion between communication protocols, the conversion between analog signals and digital signals, the conversion of control commands, real time audio code / decode, ip call control, control of rtp / rtcp, call detail logs, accounting and some of gatekeeper ' s functions such as address tansfer / search.
它提供以下功能：傳輸格式間的轉換，通信規程間的轉換，音頻、數據格式轉換，呼叫控制信令的轉換，對pstn的呼叫控制功能， pstn電路交換功能，實時語音處理語音壓縮功能， ip網路呼叫控制功能，對實時對話協議rtp rtcp的控制功能，呼叫日誌，計費功能，還包括關守的地址翻譯搜索等功能。 -
