Main Head End
A central Head-end is an area where all the services reside. This is useful when a variety of systems are used. For example when the phone rings the music can be muted in the room that the extension is picked up in. It is very likely that almost all electrical items in the home will soon be talking to a control system. The white goods within a kitchen are already internet compatible so why not have an important e-mail displayed on the TV you are viewing.
Local Head End
A local Head-end is an area within a room or zone services reside. This can be an amplifier or it can be a complete Home Cinema . It could be a PC with a printer and Fax machine.
Both of these systems should be attached to the central Head-end.
