  • Methods and systems for simultaneous, multi-channel link fault sectionalization testing
    Publication number: 20050185590
    Abstract: Method and systems for simultaneously performing link fault sectionalization (LFS) tests for multiple time division multiplexed (TDM) channels are disclosed. An LFS test state machine may simultaneously process test data for multiple TDM channels by receiving test data associated with the TDM channels, accessing stored LFS state information associated with the TDM channels from an LFS state storage element, sequentially processing the test data for the channels, generating new LFS state information for each channel, and storing the new LFS state information in the LFS state storage element.

  • Extending processors from two-way to four-way configuration
    Publication number: 20030074506
    Abstract: A computer system extends the capacity of processors with limited external arbitration and operable only for two-way or dual mode operation. The two-way processors operate on a system bus in a four-way configuration at comparable performance levels to high end, four-way processors. A bus agent or arbiter allows the system to use two-way configured processors to operate with the performance of those specifically configured for four-way node operation.
