Re: [STDS-802-3-EPOC] Updated PMD Outline Proposal

Marek,

The term used by the P802.3bj amendment is "FEC codeword".
See P802.3bj D2.1 Clause 91.

Thank you, Joe,

Such a clarification statement ought to be included in your presentation outline. As for a reader of an Ethernet standard, when I see a word "frame" my first tendency is to interpret that as a MAC frame, rather than LDPC frame.

Probably, the more proper term might be "FEC frame" or something in the lines of. I am sure on the call we can come up with 30 ways to name it right :)

Regards

Marek

The frame we are referring to is the "LDPC frame" - the block of LDPC bits. Maybe frame is the wrong term. It's related to the frame error rate referred to in the project objectives, but is to specify the performance of the receiver at the PMD layer.

We can discuss on the call tomorrow to improve the terminology.

Thanks for the question!

Hi Joe,

A quick question on page 11 - you're listing here "100.2.7.2 Frame Error Rate" and I wonder what "frame" you really mean - is this OFDM frame or Ethernet frame? In either case, clarification is warranted, since at this level Ethernet frames are rather hard to delineate with all the encoding on top of them ...

Team,

Please find attached an updated PMD outline; we will be reviewing this presentation during the "pre-socialization" meeting next week (Wednesday, 10 ET).
