ITU-T G.117 SPANISH-1996 对地不平衡的传输问题.12号研究组

This Recommendation gives a comprehensive set of prescriptive measurements of various balance parameters for one- port and two-port networks. These are intended for use either in the field or in the factory with relatively simple test apparatus (e.g. standard transmission oscillators, level measuring sets), and a special test bridge. Measuring arrangements for assessing the degree of unbalance are covered in Recommendation 0.9[1], which are consistent with this Recommendation.

ITU-T G.115 FRENCH-1996 告知和语音合成系统的平均有效话音电平.12号研究组

With the deployment of automatic announcement systems and of speech synthesis systems in the telephone network, it is necessary to specify the proper level of the generated speech. The actual speech levels of live speech in the network depend on the send and receive efficiencies of the telephone sets. Recommendation P.310 specifies long-term objectives for the SLR and RLR of digital telephone sets. Different networks have different values of SLR and RLR in their telephones. Thus, the speech levels vary from one network to another. Information on actual speech levels in different networks and for different types of calls, e.g. national and international, is found in [i].
