PURPOSE:To monitor the position of each radiotelephony set through the operation from an external equipment. CONSTITUTION:Connectors 6-9 receive a position registration signal emitting from radiotelephony sets 10-15 and sends the position registration information to a central controller 2 via line controllers 4-5. The central controller 2 registers the position of the radiotelephony sets 10-15 based on the correspondence between the radiotelephony sets 10-15 and the connectors 6-9 and when the radiotelephony sets 10-15 are move to the outside of the registered zone, the position information registered already by a position registration signal received by the connectors 6-9 after the movement is updated. The updated or registered position information of the radiotelephony sets 10-15 is stored in the database 18 of an external computer 17 via an interface bus 16 by an interface controller 3.
