Abstract: For modem connections via telephone lines, modems that respectively correspond to the modems of the terminal equipment side are arranged in the subscriber line circuits of the telephone switching centers as close as possible to the entry point of the subscriber line circuits. Modem communication only respectively between these pairs.

Abstract: A circuit arrangement for a subscriber-remote termination of a subscriber line, high-bit rate data signals and analog telephone signals. The arrangement integrates exchange-side devices, a splitter and a modem into a subscriber line circuit for the subscriber line. Additionally, the exchange-side devices, splitter and modem may be protected from overvoltages by an overvoltage protection circuit contained within the subscriber line circuit.

Abstract: A register serves for the serial acceptance of binary signals for identifying specific bit patterns in the binary signals appearing serially on a plurality of signal lines. A microprocessor, acting as a comparator, compares a respective, prescribed plurality of bits of the received binary signals to at least one prescribed bit combination. Given identification of coincidence between the respective bit combination and the bits of the received binary signals acquired in the prescribed plurality, the microprocessor emits a setting signal to a counter which counts the plurality of bits received by the register arrangement and which, when a specific count is reached, controls the transfer of the register content into a signal transfer circuit from which the register content can be accepted by a processing device.
