An International Telecommunications Union (ITU-T) standard for for audio (speech) compression and decompression that is used in digital transmission systems, and in particular, used for the coding of analogsignals into digital signals.
G.711 is also known as Pulse Code Modulation (PCM). It is the ITU-T international standard for encoding telephone audio on a 64 kbps channel. PCM samples the signal 8000 times a second; each sample is represented by 8 bits for a total of 64 kbit/s. There are two versions of the this standard codec. The ��-law (pronounced as mew law) is generally used in North America and Japan digital communications. The A-law is used in European digital communications. The difference between the two standards is the method in which the analog signal is sampled. (See also PCM).
See G.7xx for more information on how these standards are used in telephony networks.
