Method of remote-registering communication control information and

Abstract

A method of remote-registering a telephone number or similar communication control information at a mobile station such as an automobile telephone, and circuitry therefor. The mobile station is conditioned for a remote register mode in response to a command signal which is transmitted from a remote station. A modulated multifrequency signal corresponding to the modulated communication information is sent from the remote station to the mobile station which is in the remote register mode over a communication channel. The mobile station demodulates the modulated multifrequency signal to produce the original multifrequency signal, converts the demodulated multifrequency signal to a digital signal, and then stores the digital signal in a memory.
