Dear Colleagues
As we discussed in the meeting today here are my comments about a few discussion points that came up today:
1. Objectives of 1TPCE
The second bullet in the objectives includes this phrase, 'Provide electrical interoperability with existing single balanced twisted pair 100 Mb/s client
interface (OABR* PHY)' while the subscript at the bottom of the page points to the BroadRReach V3.0 specification.
As Geoff (Thompson) so eloquently pointed out in the meeting today, there is a fundamental issue with the above 2 statements. There is no evidence (empirical or otherwise) that proves that if a PHY meets V3.0 spec, then it is electrically interoperable
with existing single twisted pair PHY. Conversely there is also evidence (empirical or otherwise) that proves that every deployed OABR PHY today meets Broad-reach V3.0 specification.
I am not sure that as an IEEE spec. these 2 inconsistencies can be reconciled. I propose we change the above wording to say the following,
'Provide electrical interoperability with a PHY that meets BR V3.0 specification'.
2. PoDL questions
At the end of the session, Dave had couple of questions about PoDL. It is obvious that if we want to define a 100BaseT standard, we want to define it in such a way it reduces the external PoDL component cost. Starting with this assumption then we need
to ensure that a certain Base-line wander can be tolerated. This may mean some of the existing OABR PHYs may not function with these components which leaves us with 3 options:
a. Branch off PoDL and have different 'more expensive' components defined for 1TPCE. I am not sure why this should be the case
b. Define a coding (or a scrambling scheme) or a Wander cancellation scheme on the receive side to ensure this wander can be tolerated. Obviously in this case, some of the existing OABR PHYs may not function
c. Define a negotiation scheme. Negotiation scheme can negotiate between different speeds as well as different versions of the standard(say between 1000BASE-T1, 1TPCE and OABRV3.0). If we want to define a standard such that we can future proof it to make
it inter-operable with 1000BASE-T1, using less expensive external components for PoDL, while maintaining compatibility with previous V3.0(or 3.2 specs) then Negotiation is definitely one way that can be used.
I propose 'c'.

Betreff: [STDS-802-3] July plenary announcement
Dear Colleagues,
IEEE 802.3 will meet Monday 14th July through Thursday 17th July 2014 in San Diego, CA, USA. The IEEE 802.3 meetings are scheduled to occur in the Manchester Grand Hyatt, San Diego, CA, USA. As always, the IEEE 802 LMSC session announcement, registration
and current hotel information can be found through the 'Next IEEE 802 Plenary session notice' link on our home web page <
www.ieee802.org/3>. To receive email updates and reminders for the plenary sessions, subscribe to
the stds-802-ALL reflector <
http://listserv.ieee.org>.
The IEEE 802.3 working group (WG) opening plenary meeting will begin at 13:00 on Monday 14th July, and the IEEE 802.3 WG closing plenary meeting will begin at 13:00 on Thursday 17th July. Task Force (TF), Study Group (SG), Maintenance standing committee
and any appropriate ad hoc meetings will be scheduled between the opening and closing IEEE 802.3 meetings as illustrated in our typical schedule also found on our web site <
http://www.ieee802.org/3/plenary.html>.
The draft agenda, as well as liaison letters received so far, are available in the minutes area <
http://www.ieee802.org/3/minutes/jul14/index.html> and will be updated as required prior to the
meeting. The agenda will be approved at the meeting.
We will gather two records of attendance, the attendance tracking tool and attendance books in each meeting. The attendance tool will be the only official record of attendance for building and maintaining WG membership. The meeting attendance books will
be used to record the attendance in the minutes for each meeting and it is important that you review these minutes to make sure your attendance is recorded correctly as this will be the backup should there be an issue with the attendance tool.
Attendance credit toward membership requires attendance at three of the four days of the IEEE 802.3 session, independent of how long a particular TF or SG might be meeting. The attendance tracking tool will only allow sign in on Monday at the opening IEEE
802.3 plenary and on Thursday at the closing IEEE 802.3 plenary meeting (not during the Thursday morning meetings). A number of WG decisions are expected during the IEEE 802.3 meetings (most on Thursday during the closing meeting). Depending on the amount of
discussion, the Thursday closing meeting may run beyond our target 18:00 ending time, so please plan your travel accordingly.
Additional subgroup information follows. Information for contacting Task Force chairs, and archival project information can be found on our web site: <
www.ieee802.org/3>. Please note that IEEE P802.3bm 40 Gb/s and
100 Gb/s Fibre Optic Task Force will be holding an interim meeting on the Sunday and Monday morning prior to the IEEE 802.3 Opening plenary and that the IEEE 802.3 Industry Connections Next Generation Ethernet Passive Optical Network (NG-EPON) Ad Hoc will be
meeting on the Sunday prior to the IEEE 802.3 Opening plenary.
On the evening of Wednesday 16th July 2014 a Birds-of-a-Feather (BOF) session will be held for all attendees to gather and discuss emerging applications that may leverage or impact the overall IEEE 802 community. The format of the BOF will be short presentations
from a selected panel to seed the discussion on how emerging applications may affect, leverage, or utilize technology based on the IEEE 802 family of standards.
I look forward to seeing you in San Diego, CA, USA.

IEEE 802.3 25 Gb/s operation over a single lane call for interest
-----------------------------------------------------------------
The following request for agenda time for a 25 Gb/s operation over a single lane call for interest has been received from Mark Nowell.
----
The use of Top of Rack 4x10Gb/s breakout using 40Gb/s interfaces has become very popular over the last few years in hyper-scale data centers and cloud services providers. As these data centers prepare to transition to 100Gb/s Ethernet, there is an expectation
to use the 100Gb/s 4x25Gb/s interface specified in IEEE P802.3bj and IEEE P802.3bm as effectively as is done with the 4x10Gb/s 40Gb/s Ethernet interface. Efficient and effective data center and cloud architectures would utilize the 25Gb/s technology within
the 4x25Gb/s 100Gb/s interface technology and enable breakout to single lane 25Gb/s interfaces. At this time, there is no ability for data centers and cloud services providers to enable this network efficiency without a common specification for 25Gb/s Ethernet.
This Call For Interest is a request for the formation of a study group to 1) explore enhancements that take advantage of interfaces within IEEE P802.3bj and IEEE P802.3bm to provide a single lane 25Gb/s Ethe!
rnet specification for server interconnects, and 2) the market requirements supporting the server-TOR application of a 25Gb/s Ethernet interface.
----
The call for interest will take place during the IEEE 802.3 Opening Plenary on the afternoon of Monday 14th July. A call for interest consensus building meeting will be scheduled to occur during the week. The vote to determine if a Study Group will be
formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 17th July.
Project Authorization Requests (PARs)
-------------------------------------
The following are the PARs from other Working Groups for consideration at the July plenary. Comments are due by 17:00 on Tuesday so if there is any interest to review any of these PARs an Ad Hoc will be chartered to generate and submit the comments.

IEEE 802.3 Rules
----------------
At the March 2014 plenary we discussed two proposed revisions to the IEEE 802.3 operating rules. It is expected that a vote will occur at the IEEE 802.3 closing plenary to decide if the change should be accepted, rejected or sent out for a Working Group
ballot. For details see <
