Abstract:
1. A communications system, comprising: a physical layer device (PLD) comprising a PLD send interface including PLD parallel information outputs, and a PLD receive interface including PLD parallel information inputs; a logical link layer device (LLD) comprising an LLD receive interface comprising: LLD parallel information inputs and a deskewer for aligning received parallel information symbol strings, and an LLD send interface including LLD parallel information outputs; a parallel communications channel connecting said PLD information outputs to respective LLD information inputs and a parallel communications channel connecting said LLD information outputs to respective PLD information inputs; wherein said PLD send interface and said LLD send interface are mirrored, and said PLD receive interface and said LLD receive interface are mirrored, to thereby define symmetrical interfaces for said communications system.
