Separate channel signaling is a form of signaling in which the whole or a part of one or more channels in a multichannel Separate channel signaling system is used to provide for supervisory and control signals for the message traffic channels.
The same channels, such as frequency bands or time slots, that are used for signaling are not used for message traffic, in contrast to common-channel signaling.

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
