Abstract:

An improved telephone paging system and method are disclosed. The sytem interfaces with a conventional telephone branching system, such as a PBX, and remote pager devices which are worn by subscribers to the system. A plurality of PBX extension telephone lines are connected to the system via a subscriber line interface, and one PBX extension line is connected to this system via a control line interface. The subscriber line interface is used to detect ring signals on the selected extension lines. When a ring signal has been detected on a selected line, the microprocessor-based system sends command signals to the PBX to place the incoming call on hold. The system identifies a paging code signal distinctively corresponding to the subscriber line on which the ring signal was detected. The identified paging code signal is sent to a transmitter which transmits the paging code signal to all pagers within its range. The pager which distincitvely corresponds to the paging code signal will be activated and produce a paging signal.
