Thanks, Please see my comments. I'll
appreciate if you can address it prior the meeting so we can
Slide 2: Please use the ad-hoc Acronyms
as agreed on Annex J1 page 60 at the ad-hoc material. I am
referring to bullet 2 when you say "P2PRunb". Do you mean
End to End P2PRunb ?
The End to End P2PRUnb is system
requirement that will generate eventually the current
unbalance in addition to voltage unbalance PSE and PD. This
parameter will not be in the spec. It is a guide line or
"system" spec to us.
The parameters that will be specified
PSE PI Resistance and voltage unbalance.
PD PI Resistance and voltage unbalance.
Slide 3: No comments. It is correct.
Furthermore I am going to propose to specify minimum
resistance to PSE PI and PD PI per my presentation
conclusions sent to the reflector and to the team regarding
the channel use case analysis results. This is I believe
supported and resolve the last two bullets in this slide.
Slide 4: I like the direction. It
supports slide 3. It is also similar to the analytical way
that I have shown in the last adhoc meeting (on slide 14 of
our next meeting material) which is:
understand that the Kpd part and Kch part was merged to Y
term. Is this correct?
Looks good. Please show equation derivation to justify the
method. It will helps also to those who interested to use
it and run simulations to test the concept.
bullet not clear. (Don’t otherwise provide a balancing
bullet: Why "4 pair powering shall be sourced from a
single DC supply" is Important if Voltage difference is
It is implementation issue. We cannot require it. You need
to translate your intention to voltage, resistance,
current to allow/disallow what you believe is best and we
can discuss it.
Yes agree. I am proposing the same for PSE and PD i.e. to
derivation of equations: Please supply next meeting
calculated examples so we can verify in simulation. Please
use only adhoc numbers so we can use the same data base
and Christiam and me can both check it.
the last slide: The point is clear. Please use the adhoc
data base from the same reasons above.
I've attached a new revision of the slides for the meeting.
On 6/22/2014 8:03 PM, Darshan, Yair
Please find meeting material for
Tuesday June 24, 2014. The focus is planned to be on
slides 6-10, 13,14, 16-30.
I'll appreciate if you review the
slides per the agenda prior the meeting.
Ken: You are scheduled to present your
material from last time. Please resend it to the
