Circuit configuration and chip set for supplying a telephone subscriber loop with a supply voltage and network-side terminal of a telephone subscriber loop

摘要

A circuit configuration is provided for supplying a telephone subscriber loop with a supply voltage, for transmitting a transmitted signal into the telephone subscriber loop, and for receiving a received signal from the telephone subscriber loop. The telephone subscriber loop has a first line and a second line. The circuit configuration has a supply voltage source with a first terminal and a second terminal between which a supply voltage drops; a first circuit connected with the first line and having first and second supply voltage connections; and a second circuit connected with the second line and having third and fourth supply voltage connections. The first supply voltage connection is connected with the first terminal and the fourth supply voltage connection is connected with the second terminal. A network-side terminal of a telephone subscriber loop and a chip set are also provided.
