John, I do not believe there have been any decisions about MLSE made in .3dj yet. That said, I’m hoping some folks have experience in the field to access MLSE expectations that can be related in simple terms.
Do you think this reflector is the place to discuss expectations and broaden our understanding? Hopefully, we can move expectations into decisions.

Rich Correct me if I’m wrong please, but I don’t believe any decision has been made yet related to MLSE in the receiver.
Please note I am not speaking for or against – just procedurally. John From: Richard Mellitz <000014533bad0b9c-dmarc-request@xxxxxxxxxxxxxxxxx>
I believe it would be helpful to start public discussion about MLSE. The presentation
https://www.ieee802.org/3/dj/public/adhoc/electrical/24_0104/shakiba_3dj_elec_01a_240104.pdf by Hossein Shakiba at the past 1/4/24 IEEE802.3dj electrical ad hoc was quite extensive. There is a lot to digest there and we ran out of time. There are many
moving parts. First maybe we can simplify to make progress. The intent of the presentation seems to illustrate a comprehensive method to compute a delta SNR which equates to a delta COM. I believe the basis is delta SER when MLSE is applied. Perhaps a simple way of moving forward is to address
a straw poll as to what delta COM or delta SER folks are likely in the worldwide ecosystem and considering PVT.
Work toward our baseline could then be mediated using the barometer of expectations most folks can easily comprehend. Thank you, Richard Mellitz
