G.711
A standard analog to digital coding system (coded) that converts analog audio signals into pulse code modulated (PCM) 64 kbps digital signals. The G.711 is an International Telecommunications Union (ITU) standard for audio codecs. The G.711 standard allows for different weighting processes of digital bits using mu-law and A-law coding. The G.711 standard was approved in 1965.
G.723.1
A low bit rate standard for audio codecs developed by the ITU in 1995. The compressed bit rates for G.723.1 include 5.3 kbps and 6.4 kbps. The frame length is 30 msec and the look ahead time is 7.5 msec.
G.726
An audio codecs standard developed in 1990 by the ITU to encode G.711 PCS into compressed bit rates. This compression standard uses ADPCM compression and includes data compression rates of 40, 32, 24, and 16 kbps.
G.728
A low-bit rate audio compression standard that uses code-excited linear prediction coding to produce high quality audio with a data transmission rate of 16 kbps.
G.729
A low bit rate speech coder that was developed in 1995. It has low delay due to a small frame size of 10 msec and look ahead of 5 msec. It has a relatively high voice quality level for the low 8 kbps data transmission rate. There are two versions of G.729: G.729 and G.729 A.
G.dmt
G.dmt is an ITU standards for asynchronous digital subscriber line (ADSL). G.dmt permits data transmission rates of up to 8 Mbps downstream and 1.54 Mbps upstream.
