The BT Revelation phone system is a flexible, feature rich analogue telephone system. It can operate as a key system (calls answered by all extensions), as a PBX (calls answered by an operator) or as a combination of the above.
Control Unit sizes are: -one line plus six extensions -two lines plus six extensions -three lines plus nine extensions -four lines plus 12 extensions
Whatever size you start with, the system easily expands to the maximum capacity. Extensions can be used for key phones, standard telephones, fax or modem.
