Abstract: An address sequencer and memory arrangement is shown for transferring data in the form of message bytes to and from a plurality of digital data links. The address sequencer and memory arrangement includes a memory circuit having a plurality of memory location areas associated with each of the plurality of digital data links. A counter circuit connected to the memory circuit is loaded with a preset count by a link processor complex. The counter increments and outputs to the memory circuit addresses which sequentially access each of the memory location areas, transferring each message byte to a data link output buffer for transmission over a respective one of the plurality of digital data links. Alternatively, the counter addresses sequentially each memory location area transferring a message byte to each memory location area from each of the plurality of digital data links via a data link input buffer.
