  • Message dropout minimization when transporting isochronous packets across a plesiochronous boundary
    Patent number: 10361818
    Abstract: A system for reducing message dropout rate in a communication system is provided. Message dropouts occur during transportation of isochronous datasets across a plesiochronous boundary. The system includes a first processing element configured to operate in response to a first clock signal at a first clock speed. The system further includes a second processing element configured to operate in response to a second clock signal at a second clock speed, different from the first clock speed. The second processing element is operably connected to the first processing element by a data bus. The first processing element and the second processing element are configured to indicate a fault when no dataset is received during a processing interval. If two different datasets are received within the same processing interval one of the two datasets is dropped.
