Abstract: OPTICAL COMMUNICATION SYSTEM            Abstract A new transmission system configuration is disclosed which takes advantage of the special properties of lightwave devices and the extensive availability of frequency space on optical fibers.  The system employs a combination of time and frequency multiplexing at the transmitter, and frequency demultiplexing at the receiver. An advantageous result of combining time and frequency multiplexing is to relax the tolerance requirements on filters at the transmitter.  A further advantage is to minimize the effects of mode dispersion introduced by the fiber.

Title: Circuitry for allocating access to a demand-shared  bus
Inventor: DIMMICK JAMES O
IPC: G06F13/374

Granted: 1985-09-17
Abstract: CIRCUITRY FOR ALLOCATING ACCESS     TO A DEMAND-SHARED BUS            Abstract Circuitry is disclosed for allocating requests for demand-shared bus access among a plurality of requesting ports.  During bus contention time, each requesting unit synchronously and sequentially applies the digits of its unique priority code to the bus beginning with the most significant digit.  Each requesting unit remains in contention only so long as each digit it applies is greater than or equal to the digit applied by any other unit.  After the application of all digits, only the requesting unit having the highest code remains in contention and it seizes the bus.  A polarity control conductor is provided, selectively altering the preference that is normally specified by the assigned priority codes.          The application of a reversal signal to this conductor for a given interval of time causes each requesting unit to invert each bit of its priority code it applies to the bus during this time interval.  The polarity conductor thus permits the normal preference between units to be altered selectively in any pattern that may be desired.
