Siegfried Elstner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Modularly structured digital communication system for interconnecting terminal equipment and public networks
    Patent number: 5047923
    Abstract: Modularly Structured Digital Communications System having Operations-Oriented Communication Means. The operations-oriented communication means are distributed in three structure levels such that operating technology apparatus program modules that are associated with types of terminal equipment are provided in a line technology task structure for generating logical operating technology status messages or for setting data for operating technology terminal equipment. A coordination program module for controlling the operations-oriented information and data flow is provided in a coordination task structure and at least one application program module for sequencing application-oriented functions is provided in an application task structure.
    Type: Grant

  • Modularly structured digital communications system for interconnecting terminal equipment and public networks, and having operation and reliability programs
    Patent number: 5018097
    Abstract: Modularly Structured Digital Communications System having Operations-Oriented and Security-Oriented Components. The switching-oriented, the operations-oriented and the security-oriented components are divided into three structure levels such that apparatus program modules for generating logical switching technology messages, operating technology messages or security technology messages are provided in a line technology task structure. An operations-oriented coordination program module and switching procedure program modules for the control of the operations-oriented and of the switching-oriented information and data flow are provided in an operating technology switching technology coordination task structure. At least one operations-oriented and one security-oriented application program module for sequencing operations-oriented or security-oriented jobs are provided in an application task structure.
