How does this system work?
This telephone system helps businesses to cut cost by using a private branch exchange. With the help of this system, businesses aren’t required to run a line from every phone in the building to the telephone company’s central office.
The PBX Setup: Initially during the 20th century, PBX used to run on analog technology, but today it has gone digital. The typical private branch exchanges incorporate several phone lines from outside the building which terminates at the company exchange. It also includes several internal lines that lead to the exchange for the inside phones. A computer is used that manages the calls and switches them to one line to another based on the number dialed. This digital PBX doesn’t require a human operator.
