<p>This document specifies the CXPI data link layer and the CXPI physical layer.</p>
<p>The DLL is based on:</p>
<p>— priority-based CXPI network access;</p>
<p>— non-destructive content-based arbitration;</p>
<p>— broadcast frame transfer and acceptance filtering; and</p>
<p>— node related error detection and error signalling.</p>
<p>The CXPI physical layer (PHY) requirements comprise of:</p>
<p>— physical signalling (PS) sub-layer, which specifies the requirements of the clock generation function, the encoding and decoding of CXPI frames, and bit-wise collision resolution logic;</p>
<p>— physical media attachment (PMA) sub-layer, which specifies the requirements of the signal shaping waveform logic;</p>
<p>— physical media dependent (PMD) sub-layer, which specifies the requirements of the CXPI network termination, electrostatic discharge protection, etc., and device connector requirements; and</p>
<p>— physical media (PM), which specifies the requirements of the CXPI network cable/wiring harness.</p>
