Abstract

PURPOSE:To perform communication between fixed and mobile stations precisely in a cordless telephone consisting of the fixed and mobile stations by connecting digital code generators, digital code recognizing devices and cryptogram storages to the fixed and mobile stations respectively. CONSTITUTION:In a mobile station 50, an input applied from a fixed station to a control part 76 is decoded. If a ''TALK ON'' key is depressed, a code corresponding to the key is sent from a code generator 80 and a cryptogram stored in a memory 78 is included in the code. When an ACK code for comfirmation is received from the fixed station, the control part 76 operates a transmitter 56 and a receiver 58 so as to enable the mobile station to communicate with the fixed station. In case of a dial key input, the control part 76 generates a dial code in the code generator 80 and transmits the dial code. When code input is applied, a ringer tone is outputted to a voice amplifier 62 in case of a ringer code, and a cryptogram inputted by a dial key is stored in the memory 78 in case of a cryprogram input code.
