Hi Jon, An ECU is an Electronic Control Unit, based on this I've changed the text '.. will allow for less expensive ECUs, and more economical twisted pair ..' to read '.. will allow for lower cost Electronic Control Units (ECU), and more economical twisted pair ..'. I've attached updated drafts based on this change. I've kept the diff version to be against the initial version I sent. In respect to a short paragraph about IEEE 802 or IEEE 802.3 I've checked back to the recent IEEE 802 related releases and don't think we've include anything, not sure if that is simply because we haven't developed anything, or there is some other reason, I will check with the IEEE-SA staff on this.

I have a question -- What is "allow for less expensive ECUs"...? ECU is not identified, you may want to include an expansion of the Acronym. There is a nice paragraph about the IEEE-SA and IEEE ...why not a short paragraph about IEEE 802 or IEEE 802.3? I did see the one line and an URL, just wondering about the nominal boiler plate marking spiel...

I hope to open the email ballot in a couple of days but would be happy to receive further comments before then. Best regards, David ----- Comment 1 ----- Commenter: Pat Thaler Comment: In Thomas's quote, " The new study group will help develop another single twisted pair technology standard" A study group doesn't develop a standard (even though in this case we hope it goes as far as allowed in choosing the path). Perhaps, "The new study group expects to lay the groundwork for another single twisted pair technology standard" Or "provide the basis to initiate work on another" Response: Accept. ----- Comment 2 ----- Commenter: Geoff Thompson Comment: I see a need for one change. Specifically, the following text is incorrect: ============================================== "...today announced the formation of the IEEE 802.3 Single Twisted Pair 100 Mb/s Ethernet Study Group to explore the market opportunities and needs for multiple Ethernet speeds in automotive networking." ============================================== The above statement exceeds the scope of the Study Group that is, it is the scope of the group to explore [blah, blah] for exactly one additional speed and a specific speed at that. Therefore, I believe that the text should read: ============================================== "...today announced the formation of the IEEE 802.3 Single Twisted Pair 100 Mb/s Ethernet Study Group to explore the market opportunities and needs for a 100 Mb/s speed for Ethernet in automotive networking." ============================================== Also, I believe that the new group would have every right to move forward were the existing 1000BASE-T1 group somehow fail or get delayed. Thus, it is not "multiple" speed in that the project's existence depends in any way on there being another speed around for automotive networking. (Yes, this is splitting hairs, no, I do not expect this to happen.) Response: Accept. ----- Comment 3 ----- Commenter: Marek Hajduczenia Comment: I have a concern about the statement "to ensure that high-priority traffic is delivered predictably and with low-jitter", which implies that we cannot do that in today's Ethernet systems. In fact, I believe this to be a generally incorrect statement since (for example) EPON systems available today allow for classification and prioritization of traffic, where (high priority) premium content is delivered even when the links are congestion. From that perspective, IET provides improvement to already existing mechanisms, but not a ground breaking mechanism to do so. I would suggest the following revision to the last sentence in the second para to read: "Additionally, the IEEE P802.3br™ Interspersing Express Traffic Task Force is working to develop a draft standard providing improved hardware-level support for IEEE 802.1™ Audio/Video Bridging and Time Sensitive Networks, which provide predictable, low-jitter delivery of high-priority traffic even over congested links." Response: Accept. Furthermore, I would suggest that this text be given its own paragraph and not be glued to paragraph focused on automotive applications. Right now it is pushed in the middle of text on cars and sticks out of the context. Response: Accept. ----- Comment 4 ----- Commenter: John D’Ambrosia Comment: I agree with Geoff on this point, and try as I may, trying to expand this in this paragraph is very challenging. Other thoughts include – Additional Change #1 Additionally, the IEEE P802.3br™ Interspersing Express Traffic Task Force developed a draft is developing a standard that will provides hardware support for IEEE 802.1™ Audio/Video Bridging and Time Sensitive Networks to ensure that high-priority traffic is delivered predictably and with low-jitter. Response: Accept. Additional Change #2 Many users, premium and volume vehicle manufactures, and their suppliers, desire an IEEE 802.3 standards-based interoperable solutionsin order to enable and extend a multi-vendor supplied eco-system for the automotive industry. Not all While some automotive sub-systems require a 1 Gb/s Ethernet connection., sSmaller, less powerful Electronic Control Units (ECUs) may only be able (or need) to support a 100 Mb/s Ethernet connection., enabling the use of A reduced data rate will allow for lower-performance, more economical twisted pair wiring. to be used. As a result, automotive vendors are looking for an IEEE standardized, interoperable solution at 100 Mb/s speeds. Response: Accept in principle. See response to comment 5 below. ----- Comment 5 ----- Commenter: Geoff Thompson Comment: My own preference would be to keep this press release focussed on 100 Mb/s, thus I would rather not even have the text encompassed by John's change #1 As for change #2, how about something like: Many vehicle manufactures, and their suppliers, desire IEEE 802.3 standards-based interoperable solutions in order to enable and extend a multi-vendor supplied eco-system for the automotive industry. While an increasing number of automotive sub-systems will require a 1 Gb/s Ethernet connection, the stringent economic constraints of the volume vehicle environment only allow the use of a 100 Mb/s Ethernet connection in many of the applications. A reduced data rate will allow for less expensive ECUs, and more economical twisted pair wiring. As a result, automotive vendors are looking for an IEEE standardized, interoperable solution at 100 Mb/s. Response: Accept. ----- Comment 6 ----- Commenter: Pat Thaler Comment: I approve, but some of the text should be amended. In addition to what Geoff pointed out, Thomas's quote includes, " The new study group will help develop another single twisted pair technology standard" A study group isn't chartered to develop a standard. Perhaps, "The new study group expects to lay the groundwork for another single twisted pair technology standard" Or "provide the basis to initiate work on another" Response: Accept in principle. The text in the quote has been change to read: ‘The new study group expects to lay the groundwork for another single twisted pair technology standard’.

Since the development of this press release was at the request of the Study Group Chair and myself I'm seeking EC approval. Based on this I would like to request review before proceeding to an email ballot, therefore please provide comments on the attached draft by Monday 12th May, 2014 11:59PM AOE.
