  • Frame transfer device for a fixed format frame transmission network
    Patent number: 5263028
    Abstract: A frame transfer mechanism for a processor controlled network node connected to network link wherein fixed-length data frames including a fixed number of slots are to be transferred to and from a memory (10) under processor (23) control. The incoming data flow through a FIFO-IN shift register (22). The outgoing frames flow through a FIFO-OUT (24) register. Both FIFO shift registers are provided with an extra bit position which is used to insert a synchronization-bit (flag) used to control synchronization operation of the system and incoming frames. The extra-bit position is fedback from FIFO-OUT to FIFO-IN to enable wrap-test operation.
