Methods of setting up expandable Phone Systems

April 6th, 2008

The  expandable Phone Systems refer to systems having a number of connected lines.  They are very often used in small businesses and offices. Expandable Office Systems are specially noted for their expandability. Another special feature of expandable Phone Systems is the proposition of having individual line selection buttons for each connected phone line. Dialable intercoms may also be present in some systems. The telephone systems are set up using three principal architectures. They include electromechanical shared-control, electronic shared-control and independent key sets. Before the development of large scale integrated circuits, the systems were built out of the same electromechanical components called relays just as larger switching systems are made.
