TEXT TRANSMISSION USING DTMF SIGNALLING

A method and system for transmitting text information using multifrequency signals is provided. A switching center transmits a first multifrequency signal indicating the start of a text transmission. A receiver unit receives the first multifrequency signal and prepares to receive text information. The switching center transmits to the receiver unit a second and third multifrequency signals after the first multifrequency signal. The second and third multifrequency signals contain information corresponding to a text character. The receiver unit receives the second and third multifrequency signals and determines the text character transmitted. The switching center transmits a fourth multifrequency signal to the receiver unit indicating the end of the text transmission.
