Abstract
A circuit arrangement for connection of information transducers, which may be compensating networks in program controlled telecommunication exchange systems is described. In the system the transfer of information between the feeder and consumer lines connected to a line connection unit always occurs over a central memory. The storage areas in the central memory, which are connected to feeder lines, can be reached over input code transducers and contain an address datum identifying the desired outgoing or consumer lines. By means of the address datum, the consumer lines can be reached over output code transducers. Compensating networks are connected at the input end to the outputs of the output code transducer and at the output end to inputs of the input code transducer. Applicable outputs of the output code transducer can be reached over an address datum contained in an associated storage area. Specific storage areas connected to applicable inputs of the input code transducer can be reached over these inputs. These storage areas each contain an address datum identifying the desired consumer line.
