Abstract

1,111,573. Automatic exchange systems. SIEMENS A.G. 24 Aug., 1966 [25 Aug., 1965], No. 37866/66. Heading H4K. A group of line circuits is served by a group of impulse correcting circuits, the appearance of the first pulse in a train to be repeated by the line circuit causing the connection of a free one of the correcting circuits. Should all the correcting circuits be in use busy tone is connected. A counting chain times release of each correcting circuit.
