Abstract

1,075,006. Automatic exchange apparatus. SIEMENS A.G. Sept. 14, 1965 [Sept. 15, 1964], No. 39160/65. Heading H4K. An exchange discriminates between subscribers provided with impulse transmitters and those provided with code senders. On connection to a group selector over a preselector stage the line circuit of a subscriber provided with a code sender discharges a capacitor over the C- wire thereby operating a relay which brings in a code register. In a line finder system the capacitor may be provided in common by being positioned in the allotter circuit.
