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.
