Abstract
Signal transmitting apparatus in encrypted pulse modeling telephone systems, between a pair of terminals, based on a predetermined number of numerical spaces or intervals for message transmission, composed of a detector to determine the state of the direct current signals by at least one of the terminals, and a transmitter that responds to the detector to transmit, at least in one direction and towards the other terminal, a binary state corresponding to the determined state of the direct current signal, the particular binary state being concordant with the respective states of the direct current signal; characterized by means in the transmitter for adding an additional numerical space, apart from the message spaces, and transmitting the binary state via a path that selectively comprises the additional numerical space and the least significant of the message spaces; and by a regenerator to reconstruct in the opposite terminal, in response to the transmitted binary state, the detected state of the direct current signal.
