ABSTRACT:
A system for automatically storing one or more pauses in a device for memorizing a dialing sequence such as a telephone number includes a device for instantaneously detecting the appearance, persistence and interruption of a substantially continuous signal on a line such as a telephone line in a time period shorter than a human listener requires to perceive this signal and dial one number of the sequence; a device for detecting engagement of a key for generating, on the telephone line, a signal representing at least one member of the dialing sequence; a device for delaying generation of the signal associated with the engaged key to test for persistence or interruption of the substantially continuous signal on the telephone line in a time period substantially imperceptible to the human listener; and a device for memorizing each member of the dialing sequence at its correct position in the sequence with a pause automatically stored before any member if the substantially continuous signal persisted on the telephone line after engagement of the key representing that member.
