Agenda
- Per the meeting announcement.
Discussion (TWDP)
- A presentation for organizing the call was uploaded. See http://ieee802.org/3/aq/public/upload/TWDPworkafterLondon.pdf.
- Agreement on objectives for the call (slide 2).
- Agreement on the decisions required (slide 3).
- The first 3 decisions are strongly coupled.
- Some comments about other tests, but our actions are to resolve TWDP
comments. If other tests are required, they should be submitted as
comments.
- Agreement on basic steps required (slide 4).
- EQ length (slide 6)
- Discussion that pass/fail for TWDP should adjust for EQ length.
Adjustment supported from budget for implementation penalty.
- 14,6 proposed, 10,3 and 8,2 also mentioned as possibly being more
typical today.
- Agreement that test should not recommend any EQ configuration, so
exact length used should not be interpreted as such. EQ configuration used
should only represent a benchmark to which to compare and tradeoff with
other implementation loss options. It need not be typical, but its results
should correlate and be predictive of what would happen with other
configurations.
- Vivek agreed to study earlier results of TWDP results to quantify
correlations among EQ length and measured waveforms and present findings
and recommendations to the group.
- TWDP limits should relate to TP3 stress to help assure link closure.
- As a test of our TP2 work and the standard, receiver designers must
determine if waveforms that pass TP2 test can be received within BER
requirements; if not, committee must decide whether tests are okay or
not.
- Link closure metric (slide 7)
- Agreement that correct options are listed.
- We did not have agreement on what is best.
- ClariPhy will simulate and compare preferred options across a range of
measured waveforms and present findings and recommendations to the
group.
- Equalizability (slide 8)
- Agreement that this is possibly covered by work on EQ length and link
closure metrics and that no separate work is obvious at this
time.
- Data sequence (slide 9)
- Not discussed due to lack of time.
- Tom received and traded emails from/with John Ewen offering to
help in this area.
- The first work will be to test and/or simulate the current pattern and
compare penalty results against the prbs9 pattern using a range of
reasonable (expected to be compliant) waveshapes.

Agenda
- Proposed discussions
- This week will be only about TWDP, so participation should be very
focused. The goal is for TWDP to provide the most relevant and
meaningful metric(s) for LRM. We will be discussing what decisions are
required and what work should be done to get there. We'll have a
presentation to help guide us.
- Next call
Thanks, Tom
