PHY Data Field Definitions
Operational Attributes Area
• Pair A/B/C/D Signal-to-Noise (SNR) Margin - Displays the CNA's MDI interface average SNR
margin for twisted pairs A, B, C & D.
Error Rates Area
• Low Density Parity Check (LDPC) Frame Errors - The LDPC counter tracks the number of LDPC
frames received by CNA's MDI interface that can not be corrected. This counter self-clears at
MDI link down.
• Pair A/B/C/D Mean Squared Error (MSE) - Displays the CNA's MDI interface average Mean
Square Error relative to the transmitted codewords for twisted pairs A, B, C & D.
Counters Area
• MDI PLL Events - The MDI PLL Event counter tracks events that affect CNA's normal operation.
This counter self-clears at MDI link down.
• 10G EMI Events - The 10G EMI Event counter tracks the number of single-tone interference
detected by CNA's MDI signals. This counter holds its value at MDI link down and self-clears at
the next link up.
• PHY Frames - Counts the number of PHY frames transmitted and received since the MDI link
has been established. This counter holds its value at MDI link down and self-clears at the next
link up.
