Abstract
Binary-coded message communication for accessing, over a telephone line, a unit such as a telephone-answering device. Communication takes place through the use of time-space-assigned bursts of two different audio frequencies. One frequency is used in a single burst to define the beginning of a message, and the other frequency is used in one or more bursts to define a selected binary-code--the code being determined in accordance with the time-locations of such burst(s).
