Switching in which many processor-controlled switching units are distributed, usually close to concentrations of users, and operated in conjunction with a host switch.
Note: Distributed switching provides improved communications services for concentrations of users remote from the host switch, and reduces the transmission requirements, i.e., the traffic, between such concentrations and the host switch.

A distributed multi-access network that (a) supports integrated communications using a dual bus and distributed queuing, (b) provides access to local or metropolitan area networks, and (c) supports connectionless data transfer, connection-oriented data transfer, and isochronous communications, such as voice communications.

In ISDN applications, the use of broadband transmission of audio or video information to the user without applying any post-production processing to the information.
Note: "Distribution" is in contrast to "contribution. "

An active linear device that accepts, at its input port, one signal source (e.g., audio, video, or rf) and presents it, usually in lossless or amplified form, at two or more output ports.
Note: A distribution amplifier may also serve as an impedance-matching device.

In communications, a structure with terminations for connecting the permanent wiring of a facility in such a manner that interconnection by cross-connections may readily be made.

Synonym list server.

In ISDN applications, a telecommunications service that allows one-way flow of information from one point in the network to other points in the network with or without user individual presentation control.

The voltage drop between any two defined points of interest in a power distribution system.

Television conforming to the NTSC standard, the SECAM standard, the PAL standard, or the PAL-M standard. Synonym [in ITU-T usage] existing quality television.

In data transmission, a device that accepts a data stream from one line and places a sequence of signals, one or more at a time, on several lines, thus performing a spatial multiplexing of the original stream.
Note: Examples of a distributor are (a) a mechanical unit with input to a rotor and output through many contacts wiped by the… (Read More →)
