[802.3_SPMD] Closing remaining comments - R1-39



All – I encourage you to use the reflector to close the remaining comments.  I will start a thread on each.  This one is for R1-39.

 

Comment R1-39 relates to providing isolation requirements for PHYs that do not implement an MPI and proposes basing one off clause 40.6.1.1.

 

In discussion, we needed to write a PICS option, and we also notice we had missed the PICS for PHYs that DO implement an MPI. Jason Potterf was kind enough to work this resolution offline, and following that, the proposed resolution is:

 

PROPOSED ACCEPT IN PRINCIPLE.

Insert the following text as a new paragraph at the end of Section 188.6.1:

 

A PHY with a TCI that is not an MPI shall provide electrical isolation (see J.1.2) between the port device circuits, including frame ground (if any) and all MDI leads.

 

Insert new PICS major capabilities/options in 187.12.3 (P129 L17)

Add new row to PICS table 188.12.3

*MPOE

Implements MPSE or MPD Behavior

189.1.2

Provides power to or sources power from the mixing segment

O

Yes []
No []

 

Insert new PICS PMDE1 and PMDE2 on P132 L8 and renumber remaining PICS.

 

Item: PMDE1

Feature: Electrical isolation between port device circuits

Subclause: 188.6.1

Value/Comment: A TCI that is not an MPI provides electrical isolation between the port device circuits, including frame ground (if any) and all MDI leads, in compliance with J.1.2.

Status: M:!MPOE

Support: Yes [ ], N/A [ ]

 

Item: PMDE2

Feature: Electrical isolation between port device circuits

Subclause: 188.6.1

Value/Comment: A TCI that is  an MPI provides electrical isolation according to 189.6.2

Status: M:MPOE

Support: Yes [ ], N/A [ ]
