聲音頻帶

The types of non-voice signals considered include voiceband data, network signalling, circuit continuity tones, and dual-tone multi-frequency signalling. 考慮的非話音信號的類型包括：話帶數(shù)據(jù)、網(wǎng)絡(luò)信令、電路連接單音以及多音多頻信令。

This Recommendation provides transmission performance guidelines for voiceband services over networks that are an interconnection of an IP network (e.g. 本建議提供了IP網(wǎng)絡(luò)和PSTN互聯(lián)上語音帶業(yè)務(wù)的傳輸性能指導(dǎo)。

This tendency, together with the reality that voiceband communications will be an important source of traffic on such networks, has led ITU-T to develop this Recommendation. 這個趨勢，和這樣的事實：語音帶通訊在該網(wǎng)絡(luò)上將會成為一個重要的交通資源，使得ITU-T開發(fā)該建議。
