An International Telecommunications Union (ITU) standard for for audio (speech) compression and decompression that is used in digital transmission systems, and in particular, used for the coding of analog signals into digital signals.
G.729 is an ITU-T audio data compression standard that operates at 8 kbit/s using a conjugate-structure algebraic-code-excited linear-prediction (CS-ACELP). This algorithm for voice compresses voice audio in 10 millisecond frames. G.729 is commonly used in in Voice over IP (VoIP) applications because of its inherently low bandwidth requirement. Extensions to the G.729 standard include the following;
G.729a (G.729 Annex A) – Compatible with G.729 Annex A specifies a coder with several simplifications, including code book search routines. These modifications are known to often result in a slightly lower voice quality.
G.729b (G.729 Annex B) – Compatible with G.729, Annex B specifies a coder that uses Discontinuous Transmission (DTX), Voice Activity Detection (VAD), and Comfort Noise Generation (CNG) to reduce bandwidth usage. Bandwidth is reduced by preventing the transmission of non-voice during periods of silence.
See G.7xx for more information on how these standards are used in telephony networks.
Refers to a suite of International Telecommunications Union (ITU) standards for audio (speech) compression and decompression. This family of standards is included in the G Series ITU Recommendations. The G.7xx recommendations are used in digital transmission systems, and in particular, used for the coding of analog signals into digital signals. Telephony networks employ a system […]
A Generic port (G_Port) within a Fibre Channel switch that can operate as either an E_Port or an F_Port.
Also known as G.991.2, G.SHDSL is an international standard for symmetric DSL developed by the ITU. G.SHDSL provides for sending and receiving high-speed symmetrical data streams over a single pair of copper wires at rates between 192 kbps and 2.31 Mbps. G.SHDSL was developed to incorporate the features of other DSL technologies, such as ADSL […]
G.lite (also known as Universal ADSL, and referred to as G.992.2 by the ITU ), allows for high-speed “always on” digital communications over standard copper phone lines. While it is based on the same underlying technology as standard ADSL, G.lite doesn’t require a splitter to be installed at the customer location. The customer simply connects […]
Known as W32.Gammima.AG, it is a worm that spreads through removable media such as USB drives and external hard drives, and is known to steal online gamers’ user names and passwords. Gamimma steals sensitive information for various online games, including ROHAN, R2 (Reign of Revolution), Talesweaver, Seal Online, and several games popular mainly in China, […]
