A process within the communications management network that acts on information passing between network elements (NEs) and operating systems (OSs) via a data communication network. Mediation uses standard interfaces and can be shared among several NEs, or several OSs, or between NEs and OSs. [T1.201-1987] [T1.204-1988]

In telecommunications network management, a function that routes or acts on information passing between network elements and network operations.
Note 1: Examples of mediation functions are communications control, protocol conversion, data handling, communications of primitives, processing that includes decision-making, and data storage.
Note 2: Mediation functions can be shared among network elements, mediation devices, and network operation centers.

1. In telecommunications, the transmission path along which a signal propagates, such as a wire pair, coaxial cable, waveguide, optical fiber, or radio path.
2. The material on which data are or may be recorded, such as plain paper, paper tapes, punched cards, magnetic tapes, magnetic disks, or optical disks.

In a communications system, the equipment that adapts or formats the signal for transmittal over the communication medium.
Note 1: An example of a MAU is an optical transmitter, which accepts an electrical signal at its input port and converts it to an optical signal accessible at its output port.
Note 2: Some prefer to limit the term medium access… (Read More →)

Frequencies from 300 kHz to 3000 kHz. See electromagnetic spectrum.

In communications systems, the connector at the interface point between the bus interface unit and the terminal, i.e., the medium interface point.

In communication systems, the location at which the standards for the interface parameters between a terminal and the line facility are implemented.

A hypothetical talker, within a log-normal distribution of talkers, whose volume lies at the medium power of all talkers determining the volume distribution at the point of interest.
Note: When the distribution follows a log-normal curve (values expressed in decibels), the mean and standard deviation can be used to compute the medium-power talker. The talker volume distribution follows a log-normal… (Read More →)

Bit error rate that can be encountered for relatively short time periods (e.g., minutes), due to temporary malfunctions of, for example, transmission equipment. [T1.110-1987]
