Patents by Inventor H. John Lohn, III

H. John Lohn, III 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).

  • Patent number: H1940
    Abstract: In a telecommunications system, components which fail and have backup resources are dynamically remapped to insert the backup resource in place of the failed component. A configuration database containing data for each resource in the switching platform of a telecommunications systems can be dynamically searched to identify backup resource and dynamically updated to reflect addressing and connection data for remapped components, thereby allowing dynamic replacement of failed components in the switching platform that is transparent to the applications processor of the telecommunications system.

  • Patent number: H1801
    Abstract: A switching module capable of sending heartbeat messages and identifying other elements within a telecommunications switching platform as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which it can run its operating system. The module can also transfer the operating system into another memory, allowing the module to make updates to the operating system stored in the nonvolatile memory without interrupting its execution of its run-time operating code.

  • Patent number: H1804
    Abstract: An interface module capable of responding to heartbeat messages and identifying itself as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which the module can run its operating code. The module can also transfer the operating code into another memory, allowing it to make updates to the operating code stored in the nonvolatile memory without interrupting its execution of its run-time operating code.

  • Patent number: H1814
    Abstract: A telephony-support module capable of responding to heartbeat messages and identifying itself as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which the module can run its operating system. The module can also transfer the operating system into another memory, allowing it to make updates to the operating system stored in the nonvolatile memory without interrupting its execution of its run-time operating code.

  • Patent number: H1860
    Abstract: In a switching platform of a telecommunications system, fault testing is automatically performed during operation of the switching platform to identify components to be tested, perform testing and if a fail condition occures, perform localization to isolate a source of the fail condition. In another mode of testing, an off-line component is identified and the test procedure automatically performs testing and if a fail condition occurs, a localization procedure is automatically initiated to identify a source of the fail condition. A configuration database containing status information on components of the switching platform can be periodically searched by the fault test procedure to identify components to be tested. The configuration database can also be searched to identify replacement components in response to an alarm identifying a faulty component generated by the fault test procedure.

  • Patent number: H1882
    Abstract: A system, and associated methods, for transferring data to redundant components of a telecommunications system is provided. The system includes a synchronization client operating on a component. The system also includes a synchronization server operating on another component. The synchronization client is operable to transfer predetermined data to the synchronization server upon the occurrence of a predetermined condition.

  • Patent number: H1917
    Abstract: Described is a system and method for transcoding and rate-adapting between information channels having a first rate and signal-encoding scheme and information channels having a second rate and second signal-encoding scheme. Further described is a system and method for determining when a signal-processing module has failed or been removed or inserted into an operating telecommunications switching platform. Also described is a system and method for efficient power-up, to allow for more efficient system power-up, the signal-processing modules of the present invention preferably have their operating systems stored in a nonvolatile memory that can be reprogrammed without removing it from the system. A switching module is further capable of responding to heartbeat messages and identifying itself as operational over one bus or both buses of a redundant-pair control bus. The module also has a reprogrammable, nonvolatile memory associated with it from which the module can run its operating system.
