Abstract

PURPOSE:To prevent a telephone set in the same group from starting to ring simultaneously to a calling signal sent from a main equipment by generating a calling sound in the beginning when the number of the times of calling from a main equipment is coincident with the set number of the time of calling. CONSTITUTION:The input of an operation key 8 is executed so that the preset value of a counter 7 of telephone sets 1a and 1b can be '1.' The key 8 is operated so that the preset value can be '2,' by telephone sets 1c and 1d. In the telephone sets 1a and 1b, when a calling signal S11 is sent from a main equipment 2 to a decoder 4, the counter 7 operates a driving circuit 5 since the preset value '1' and the number of the times of the calling signal sent from the decoder 4, which is '1,' are coincident. In the telephone sets 1c and 1d, the number does not reach the set number of the times by a first calling signal S11, and therefore, the driving circuit 5 is not operated. When a second calling signal S12 is inputted to the decoder 4, a calling sound is generated from a speaker 6.
