Hi Colleagues,
I will not be attending Milwaukee meeting, but wanted to suggest different remedy to comment r02-14 on clause 146.8.1/147.9.1 by
Christopher Diminico (Please see comment at the end of the email) which suggest to add IEC 63171-1 to 8023cg_D3dp2, but does not include IEC 63171-6.
We have had long discussions, various proposals, straw polls, motions and have built consensus, but not fully satisfying everyone.
I also think IEEE 802.3 should provide some direction as “may be used” for the eco-system to develop MDI connector/interface. This means we should not over restrict
MDI connector by tying to different applications such as – Automotive, Industrial or Enterprise or any other application as in 8023cg_D3dp1 CL 146.8.1 and CL 147.9.1.
Number of task force attendees from OEMs, Cable, Test Equipment and Connector industries drafted text and built consensus that allows eco-system to use MDI connector
as required by their application built conscious in the sections below.
“8023cg_D3dp0 CL 146.8.1 page 153 line 6 to page 155 line 7 AND
8023cg_ D3dp CL 147.9.1 page 200 line 17 to page 202 line 54”
Note: IEC 610176-125 reference needs to be changed to IEC 63171-6
Suggested Remedy
Take text and figures
“8023cg_D3dp0 CL 146.8.1 page 153 line 6 to page 155 line 7”
Insert in 802cg_D3dp2 CL 146.8.1 page 171 line 46 But correct reference IEC 610176-125 TO IEC 63171-6. Editorial license to revise figure numbers as need
……………………………..
Take the test and figures
8023cg_ D3dp0 CL 147.9.1 page 200 line 17 to page 202 line 54”
Insert in 802cg_D3dp2 CL 146.9.1 page 220 line 45, But correct reference IEC 610176-125 TO IEC 63171-6. Editorial license to revise figure numbers as needed

The continued success of BASE-T technology is largely predicated
on leveraging the cost-effectiveness and plug-and-play simplicity
ensured by compatibility at the MDI. We need to be forward
thinking in developing a compatible user interface for BASE-T1.
The MDI is to specify mechanical compatibility and electrical
specifications not EMC conformance.

146.8.1 MDI connectors -Page 179, Line 1 add text;
Connectors meeting the mechanical requirements of IEC 63171-1
may be used as the mechanical interface to the balanced cabling.
The plug connector is used on the balanced cabling and the MDI
jack connector on the PHY.
Re-instate IEC 63171-1 plug and jack figures from D3.1. with
text below.
Editorial license to revise figure numbers as needed.
The IEC 63171-1 plug and jack are depicted (for informational
use only) in Figure 146-29 and Figure 146-30 respectively,
and the mating interface is depicted in Figure 146-31.
The assignment of PMA signals to connector contacts for
PHYs are given in Table 146-8.
147.9.1 MDI connectors -Page 227, Line 1 add text;
Connectors meeting the mechanical requirements of IEC 63171-1

The plug connector is used on the balanced cabling and the MDI
jack connector on the PHY.

the mating interface is depicted in Figure 147-23. The
assignment of PMA signals to connector contacts for PHYs are
given in Table 147-3. These connectors should support link
segment DCR characteristics for 1.02 mm (18 AWG) to
0.40 mm (26 AWG) in Table 146B-1.
