    Abstract: A public telephone set that processes call charge information is provided. The set includes a register for holding a pre-determined number of digits of the dialed number and a memory in which dial control codes corresponding to the predetermined number of digits are stored in advance. Depending upon the telephone number that is dialed, a memory location is directly addressed to obtain a control code. The control code specifies a memory location in which charging information such as a charge or time increment is stored.
