Abstract

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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 189 words
A circuit arrangement for connecting information transducer means in a program controlled telecommunication switching system in which the transfer of information between incoming and outgoing line means occurs over a central memory, said line means being connected to a line connection unit, said central memory including a plurality of storage areas allocated to given incoming line means and accessible over input code transducers, each said storage area containing an address datum identifying an outgoing line means, each said outgoing line means being accessed, by means of said address datum, over an output code transducer, the circuit arrangement comprising: a plurality of information transducer means having, respectively, input and output terminals, said input terminals being connected to outputs of said output code transducers, said output terminals being connected to inputs of said input code transducers, each said information transducer means being identified by data accessible through an address contained in one of said storage areas allocated to an incoming connection through an incoming lines means, the address identifying an outgoing connection being contained in the one of said storage areas allocated to the connected one of said information transducer means.
Claim 2
Dependent Claim 189 words
A circuit arrangement for connecting information transducer means in a program controlled telecommunication switching system in which the transfer of information between incoming and outgoing line means occurs over a central memory, said line means being connected to a line connection unit, said central memory including a plurality of storage areas allocated to given incoming line means and accessible over input code transducers, each said storage area containing an address datum identifying an outgoing line means, each said outgoing line means being accessed, by means of said address datum, over an output code transducer, the circuit arrangement comprising: a plurality of information transducer means having, respectively, input and output terminals, said input terminals being connected to outputs of said output code transducers, said output terminals being connected to inputs of said input code transducers, each said information transducer means being identified by data accessible through an address contained in one of said storage areas allocated to an incoming connection through an incoming lines means, the address identifying an outgoing connection being contained in the one of said storage areas allocated to the connected one of said information transducer means.
Claim 3
Dependent Claim 22 words
The circuit arrangement defined in claim 1 wherein said information transducer means comprises a compensating network for removing distortion from data signals.
Claim 4
Dependent Claim 32 words
The circuit arrangement defined in claim 1 further comprising means for switching said information transducer means into said connections to said input and output code transducers under the control of a program.
