Re: [802.3_10SPE] Proposed response to MDI connector comment r02-14

Hi CRG,

Despite my ressoable efforts to stand firm on the use of the traditional and formal definition of MDI that MDI is a mandatory interoperability interface - functional, mechanical, etc., this response uses MDI to mean informative referenced mechanical connector.   So I'll submit a disapprove comment on this aspect of this response, should the sponsor ballot goes through another recalculation.

best regards,

146.8.1 MDI connectors -Page 171, Line 52 add new paragraph;
Connectors meeting the mechanical requirements of IEC 63171-1 or IEC 63171-6 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. 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 IEC 63171-6 plug and jack are depicted (for informational use only) in Figure 146-32 and Figure 146-33 respectively, and the mating interface is depicted in Figure 146-34. These connectors should support link segment DCR characteristics for 1.02 mm (18 AWG) to 0.40 mm (26 AWG) in Table 146B-1.

Re-instate IEC 63171-1 plug and jack figures from D3.1 as Figures 146-29, 146-30, and 146-31.
Re-instate IEC 63171-6 plug and jack figures from D3.1 as Figures 146-31, 146-32, and 146-33.


147.9.1 MDI connectors -Page 220, Line 52 add new paragraph;
Connectors meeting the mechanical requirements of IEC 63171-1 or IEC 63171-6 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. The IEC 63171-1 plug and jack are depicted (for informational use only) in Figure 147-21 and Figure 147-22 respectively and the mating interface is depicted in Figure 147-23. The IEC 63171-6 plug and jack are depicted (for informational use only) in Figure 147-24 and Figure 147-25 respectively and the mating interface is depicted in Figure 147-26.  These connectors should support link segment DCR characteristics for 1.02 mm (18 AWG) to 0.40 mm (26 AWG) in Table 146B-1.

Re-instate IEC 63171-1 plug and jack figures from D3.1. as Figures 147-21, 147-22, and 147-23.
Re-instate IEC 63171-6 plug and jack figures from D3.1 as as Figures 147-24, 147-25, and 147-26.

Editorial license to revise figure numbers as needed.

Motion #5:
Move to respond to comment r02-14 with Alternative B: (see straw polls, ACCEPT IN PRINCIPLE - Same text as "A", but with -6 as well.  (Return to the draft 3.0 text, with references corrected))
