Re: [STDS-802-3-EPOC] EPoC Evaluation Criteria and Requirements Ad Hoc

Andrea,

Thanks very much for the presentation this morning. I have a couple questions:


1)      DRA and MMP
Let's say the PHY is supporting two modulation profiles on a particular CCDN - profile A supports physical data rate of 2 Gbps and profile B supports physical data rate of 4 Gbps. Of course, there is 10 Gbps coming across the XGMII interface.  Will the DRA module have to be aware of the destination profile (either A or B in this example), and remove idle data according to the destination profile? If the frame is destined for profile A, then more idle frames will have to be removed, right?


2)      Idle frames on the coax
I just want to make sure I understand something. In your diagrams showing the addition of idle data and corresponding removal of idle data, you typically showed ALL idle data was removed - leaving only information frames+FEC+coding. Is it true that there could be idle frames that are NOT removed because the information rate doesn't fill the entire channel, and thus some idle frames are in fact transmitted on the coax along with the information frames?

Thanks!

Curtis

Subject: [STDS-802-3-EPOC] EPoC Evaluation Criteria and Requirements Ad Hoc

All,

               This is a reminder that we have an Evaluation Criteria and Requirements Ad Hoc call Wednesday at 7 AM Pacific Time (10 AM Eastern Time).

               The bridge information is in the appointment that I sent out previously.

               To provide a forum for increased socialization of presentations we will have a presentation by Andrea and Marek on Data Rate Adaptation tomorrow morning.

Agenda

*         Review IEEE-SA Patent Policy

o   https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.pdf

*         Attendance

*         Data Rate Adaptation (Andrea and Marek)

*         Other

Steve
