Latest Patents
Dotzauer's latest patents include a circuit arrangement for a small PABX with a switching matrix. This invention utilizes electronic crosspoints and integrated selector components, such as multiplexers or demultiplexers in C-MOS technology, to enhance the functionality of small PABXs. The design allows for individual dialing connection points, which are determined by a control address from a control computer unit. This enables the connection of subscriber lines for internal traffic and external traffic with exchange lines. Additionally, the switching matrix is electrically separated from other operating units by repeating coils in the subscriber and exchange lines.
Another significant patent is for an interference data alarm system. This system transmits error and condition messages from unmanned telecommunication facilities to a central exchange with a maintenance control station. To protect against interferences, a transmitting test unit is inserted in several lines used for normal telecommunications traffic. This unit can automatically select any of these lines for maintenance purposes, establishing a connection to the maintenance control station to send necessary data. A data dialog for error analysis is also possible, enhancing the reliability of telecommunications systems.
