AUTOMATIC NOTIFICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To arbitrarily control the ringer of a call incoming from the side of an automatic notification system from an emergency call agent requesting a reply. SOLUTION: This automatic notification system is provided with a return signal detecting part 13 for detecting a return signal requesting the telephone communication to return from the emergency call agent to be performed after the confirmation of a call message to the emergency call agent, a cycle converting part 22 for converting the signal cycle of the detected backward signal or signal cycle of a preset signal from a 16 Hz transmission part 23 and a telephone set control part 21 for sounding a ring back tone in the converted signal cycle. Thus, the conversion of the signal cycle can be arbitrarily set by a conversion cycle setting part 23 and call incoming from the emergency call agent can be reported by a synthesized voice or lamp indication to the outside.
