A communication channel or simply channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking.
In telecommunications, data-transfer rate is the average number of bits (bitrate), characters or symbols (baudrate), or data blocks per unit time passing through a communication link in a data-transmission system.
Digital Signal 1 (DS1, sometimes DS-1) is a T-carrier signaling scheme devised by Bell Labs.
A Digital Signal 3 (DS3) is a digital signal level 3 T-carrier.
DS0A is the interface most commonly used for SS7 networks in the US.
The E-carrier is a member of the series of carrier systems developed for digital transmission of many simultaneous telephone calls by time-division multiplexing.
G.703 is a 2016 ITU-T standard for transmitting voice or data over digital carriers such as T1 and E1.
G.711 is an ITU-T standard for audio companding.
The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second.
In telecommunications and computer networks, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.
In telecommunications, a plesiochronous system is one where different parts of the system are almost, but not quite, perfectly synchronised.
Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals.
In communication systems, robbed-bit signaling is a scheme to provide maintenance and line signaling services on many T1 digital carrier circuits using channel-associated signaling (CAS).
In telecommunication, signaling has the following meanings.
Synchronous optical networking (SONET) and synchronous digital hierarchy (SDH) are standardized protocols that transfer multiple digital bit streams synchronously over optical fiber using lasers or highly coherent light from light-emitting diodes (LEDs).
The T-carrier is a member of the series of carrier systems developed by AT&T Bell Laboratories for digital transmission of multiplexed telephone calls.
In telecommunications, transmission (abbreviations: TX, Xmit) is the process of sending and propagating an analogue or digital information signal over a physical point-to-point or point-to-multipoint transmission medium, either wired, optical fiber or wireless.
A voice frequency (VF) or voice band is one of the frequencies, within part of the audio range, that is being used for the transmission of speech.
