Common battery
Encyclopedia
In telecommunication
, a Common battery is a single electrical power
source used to energize more than one circuit
, electronic component
, equipment, or system
.
Note 1: A common battery is usually an electrolytic device and is usually centrally located to the equipment that it serves.
Note 2: In many telecommunications applications, the common battery is at a nominal -48 vdc.
Note 3: A central office common battery supplies power to operate all directly connected instruments.
Note 4: Common battery may include one or more power conversion devices to transform commercial power to direct current, with an electrolytic battery floating across the output

Telecommunication
Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded...
, a Common battery is a single electrical power
Electric power
Electric power is the rate at which electric energy is transferred by an electric circuit. The SI unit of power is the watt.-Circuits:Electric power, like mechanical power, is represented by the letter P in electrical equations...
source used to energize more than one circuit
Telecommunication circuit
A telecommunication circuit is any line, conductor, or other conduit by which information is transmitted.A dedicated circuit, private circuit, or leased line is a line that is dedicated to only one use...

Electronic component
An electronic component is a basic electronic element and may be available in a discrete form having two or more electrical terminals . These are intended to be connected together, usually by soldering to a printed circuit board, in order to create an electronic circuit with a particular function...

Output
Output is the term denoting either an exit or changes which exit a system and which activate/modify a process. It is an abstract concept, used in the modeling, system design and system exploitation.-In control theory:...
