Definitions for "G.711"
Keywords:  pcm, kbps, itu, codec, khz
Refers to the transmission of audio via a POTS (Plain Old Telephone) circuit. Frequency response is limited to about 3.5kHz.
48, 56, 64 0.125 PCM / A and m
An ITU-T recommendation about a 3.4-KHz bandwidth PCM audio coding algorithm working over the range of 32- to 64-Kbps. It forms a part of the ITU-T codec and telephony requirements. This algorithm produces telephone grade audio, especially useful in videoconferencing at aggregate bit rates above 128 Kbps.   Appendix I to G.711 adds low complexity packet loss concealment, useful for good quality audio transmission within a suite of VoIP applications.
