Abstract

PURPOSE:To easily set a time zone for inhibiting the generation of a call tone at every telephone set by storing an inhibiting time zone inhibiting the transmission of an incoming tone signal at every telephone set and avoiding the transmission of the incoming tone signal to a relevant telephone set when the time is within the inhibiting time zone. CONSTITUTION:The information of the inhibiting time zone set by an inhibiting time zone setting switch 11 is stored in an inhibiting time zone storage section 10 via an arithmetic processing circuit 2. While the inhibiting time zone is set, when an incoming signal reaches from public telephone circuits L1, L2, the arithmetic processing circuit 2 compares the current time information from a timer circuit 9 with the inhibiting time zone information from the inhibiting time zone storage section 10 and a control signal is sent to a call tone transmission circuit 6 so as not to send a speaker driving signal being an incoming tone signal to telephone sets TEL1-TELn when the current time is within the inhibiting time zone at every telephone sets TEL1-TELn. Thus, the speaker driving signal is sent only to a telephone receptacle corresponding to the telephone set not reaching the inhibiting time zone.
