WHEN REGISTERING A MAIN NUMBER INTO A PHONE, THE MANAGEMENT APPARATUS (4) REPEATEDLY EXECUTES AN OPERATION FOR COMPUTING THE MAIN NUMBER WITH THE SMALLEST NUMBER OF TERMINALS PER LINE ACCORDING TO THE STATUS OF REGISTRATION IN THE TABLE (43A), REGISTERING THUS COMPUTED MAIN NUMBER WI TH REFERENCE TO THE PHONE NUMBER OF THE TABLE (43B), AND UPDATING THE NUMBER OF PHONES IN THE TABLE (43A). AFTER COMPLETING THIS OPERATION, THE MANAGEMENT APPARATUS (4) COMPUTES THE REPORTING TIME OF EACH PHONE FOR EACH MAIN NUMBER ACCORDING TO THE CONTENTS OF THE TABLE (43A), AND REGISTERS THUS COMPUTED REPORTING TIME WITH REFERENCE TO THE MAIN NUMBER IN THE TABLE (43B). THEREAFTER, THE MAIN NUMBER AND REPORTING TIME ARE SET INTO REGIONS ACCORDING TO THE REGISTERED CONTENTS IN THE TABLE (43B).(FIG 2A).
