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.
Edit / An ITU standard PCM codec that converts analog speech to a stream of digital data and back again. G.711 converts to and from analog and digital without compression of any kind and so requires a full 64Kbps of digital bandwidth See Also: G.729A PLC
CCITT recommendation detailing a 74 kbps, 7-kHz bandwidth audio coding algorithm.
A 64 kbps PCM half-duplex codec (high quality, high bandwidth, minimum processor load).
algorithm designed to transmit and receive mu-law PCM voice (for North America) and A-law at digital bit rate 64 Kbps.

The G.711 standard, also called Pulse Code Modulation (PCM). A standard method of converting analog signals to digital signals. Typically used in public and private telephone networks, G.711 samples analog data and prepares it for transmission.
The international standard for encoding telephone audio on a 64 kbps channel. It is a pulse code modulation (PCM) scheme operating at a 8 kHz sample rate, with 8 bits per sample.
This vocoder is used in the PSTN, and is commonly called PCM (Pulse Code Modulation). There are two flavors of its algorithm; mu-law used in North America and Japan, and A-law used in the rest of the world. This vocoder algorithm produces a bit rate of 64 Kbits/second and has no silence suppression, meaning silence is transmitted and occupies bandwidth.
is the default audio representation used in H.320, providing roughly 3.5-KHz frequency response in a 64,000-bit communication channel.
An audio compression standard used for digital telephones on a digital PBX/ ISDN. G.711 uses a bandwidth of 64 Kbps. G.711-compliant devices can communicate with other G.711 devices, but not with G.723 devices.
An uncompressed codec that samples a 64kbps channel at 8 bits per sample using pulse code modulation. The Two varients of G.711 are known formally as uLaw and aLaw. See also: CODEC, G.729, GSM
3KHz audio-coding at 64Kbps.
ITU-T u-law and A-law compression. Pulse Code Modulation (PCM). A simple waveform codec that uses 64kbits/sec. There are two variations u-law used in T1 and J1 countries, and A-law used in E1 countries.
audio coding standard providing voice quality (300 Hz to 3400 Hz) at 48 / 56 / 64 kbps.
64 kbps PCM half-duplex codec (high quality, high bandwidth, minimum CPU load) See also: Codec
An ITU-T PCM half-duplex codec that uses either A-law or ?-law compression (64 kbps, high quality, minimum processor load).
An ITU-T Recommendation entitled, "Pulse Code Modulation (PCM) of Voice Frequencies". G.711 defines how a 3.1 kHz audio signal is encoded at 64 kbps using Pulse Code Modulation (PCM) and either mu-law (US and Japan) or A-law (Europe).
Audio compression at 48-64 Kbps, 3 Khz (telephone quality). Part of the H.320 standard.
Describes the 64-kbps PCM voice coding technique. In G.711, encoded voice is already in the correct format for digital voice delivery in the PSTN or through PBXs. Described in the ITU-T standard in its G-series recommendations.
ITU-TSS recommendation "Pulse code modulation (PCM) of voice frequencies". This audio standard is mandatory for all video conferencing systems. It requires a data rate of 56 or 64 kbit/s and provides an audio bandwidth of 300 ... 3400 Hz.
ITU-T recommendation for an algorithm designed to transmit and receive A-law and M-law PCM voice at digital bit rates of 48, 56, and 64 kbps. It is used for digital telephone sets on digital PBX and ISDN channels. Support for this algorithm is required for ITU-T compliant video conferencing (H.320/H.323 standard).
Codinng of speech at 64 Kbps
G.711 is an ITU-T standard for audio companding. It is primarily used in telephony. The standard was released for usage in 1972.
