epxbx What is the use of epabx? You should know that computer is an electronic machine like any other machine which takes as inputs raw data and performs some processing giving out processed data. Control Unit CU The next component of computer is the Control Unit, which acts like the supervisor seeing that things are done in sjstem fashion. Therefore the data is first stored in the storage unit for faster access and processing. An EPABX has three main components 1 the analog system and analog to digital converter which is basically the various line cards and 2 the cross connection matrix which connects one call to another and 3 the control of the whole EPABX.


Data has to be fed into the system before the actual processing starts. You may call CPU as the brain systme any computer system. This is the process of producing results from the data for getting useful information.

Again the output is also stored inside the computer for further processing.
