  • Distributed digital antenna system
    Publication number: 20040106435
    Abstract: An optical medium, such as fiber, is tapped to provide an antenna port wherever radio service coverage is desired. Each antenna port is a bi-directional remote unit that receives a digital optical signal from a host unit and transforms the signal to a radio frequency signal for transmission by the remote unit. The remote unit receives radio frequency signals that are converted to digital signals and summed with signals from other remote units and converted to an optical signal for transmission to the host unit.

  • Small signal threshold and proportional gain distributed digital communications
    Publication number: 20040106387
    Abstract: A method for signal gain adjustment in a multi-port, digital distributed antenna system uses a sorter to sort received signals in ascending order according to their signal levels. A threshold comparator generates a dynamic range fair threshold that is updated as any remaining system dynamic range is distributed amongst the remaining signals. Any received signal that is less than or equal to the threshold is attenuated with a unity gain factor. A signal that is greater than the threshold is attenuated with a gain factor that is inversely proportional to the signal level.

  • Measuring an error rate in a communication link
    Publication number: 20040107391
    Abstract: An error rate detector is provided. The error rate detector includes a sequence generator that is adapted to generate a test sequence for comparison with a received sequence. The error rate detector also includes a self synchronization circuit that is responsive to the test sequence received from the sequence generator and the received sequence. The self synchronization circuit is adapted to move the sequence generator to a different point in the sequence based on a measure of mismatches between the test sequence and the received sequence.

  • Digital cross connect module with removable jack
    Patent number: 6743032
    Abstract: A switching coax jack module and jack component provide for a removable DSX jack which can be slid into and out of the front of a jack module housing without disconnecting other components of the jack module and without disconnecting the module from a chassis.

  • Change detection in a graphical user interface
    Publication number: 20040100488
    Abstract: A first process communicates to a second process what data will be used to display a graphical user interface element such as a window or screen. The second process determines if the data used to display the graphical user interface element has changed, and, if the data used to display the graphical user interface element has changed, communicates to a third process that the data used to display the graphical user interface element has changed. Moreover, the third process receives the communication that the data used to display the graphical user interface element has changed, and, in response to the communication that the data used to display the graphical user interface element has changed, displays the graphical user interface element.

  • Polarization beam separator and combiner
    Patent number: 6741764
    Abstract: The present invention relates to a device for use in a fiber optic system that may be a communication system, a sensing system or other system using guided-wave optical components. Reducing the number of lenses required to couple the waveguides and the free-space paths in the device offers the dual advantages of a reduced component count and simplified alignment. In an exemplary device having a first and second waveguides, a birefringent optical system defines bi-directional, polarization-dependent free-space paths. One of the bidirectional, polarization-dependent, free-space paths couples at least the first waveguide to the second waveguide. The birefringent optical system includes at least one prism for bending one of the polarization-dependent paths in a clockwise direction and one of the polarization-dependent paths in a counterclockwise direction.

  • Architecture for intermediate frequency encoder
    Patent number: 6741650
    Abstract: An encoder. The encoder includes an analog-to-digital (A/D) converter that receives an analog signal. The A/D converter downconverts and digitizes the analog signal without analog mixing of the analog signal. The encoder also includes a resampler that is coupled to the A/D converter. The resampler receives the digital signal and converts the downconverted digital signal to an output signal at a data rate independent of a data rate of the digitized analog signal.

  • Configurable initialization of hardware
    Publication number: 20040098573
    Abstract: In a family of telecommunications modules or other circuit boards, driver software is divided into a core support package for initializing board components common to the family of circuit boards and one or more extended support packages specific to individual members of the family. This facilitates a reduction in the amount of programming effort needed across the family of circuit boards as the core support package need only be developed once for the family of boards rather than developing complete driver programs for each member of the family. The remaining programming effort can then be focused on the specialized subroutines. In addition, changes in hardware common to each member of the family can be accommodated by redeveloping only the core program. This need only occur once for the entire family, rather than once for each member of the family.
