Abstract
Abstract Automatic call transmitter comprising a plurality of cartridge tape recorders and readers with recording heads, readout heads, capstans and capstan motors. Magnetic cartridges can be inserted into these recorders and readers. The capstan of the recorder and reader drives the magnetic tape of the cartridge. Alternating current pulses are generated under the control of the dial of a telephone set and these pulses are applied to the recording heads and recorded on a cartridge tape. An amplifier is connected to the readout heads for reading out the recorded pulses and the read out pulses are applied to a relay connected in parallel to the dial terminals. The operation of this relay simulates the dial actuation.
