RE: [802.3_TIME] Changes to MDIO registers

["Chalupsky, David" <david.chalupsky@xxxxxxxxx>]

 

Every MMD’s set of registers points to 90.7 for the time measurement definition.

90.7 says that the measurement is from PMD to xMII.  So taken literally, each MMD would report the full PMD to xMII delay.

Then clause 30 would add them all up and report 6 times the PMD to xMII delay.

I don’t think that was your intent.

Subject: [802.3_TIME] Changes to MDIO registers

 

Dear all,

 

As part of my homework for today, I am submitting three contributions which list changes to Clause 45, Clause 30 and Clause 90 under the assumption of adding TimeSync registers into PMA/PMD, WIS, PCS, PHY XS, DTE XS and TC MDIO register sets, as discussed yesterday.

 

I would like to use these files for discussion today and resolve the remaining 5 comments related with this topic. All comments are more than welcome

 

See you soon

 

Regards,
