Re: [802.3_SPEP2P] dg meeting today October 29

Dieter - I believe Tingting was referring to PAM-2 at the same line signalling rate (baud) as the 100 Mbps PAM-3 signal would be (i.e., 80 MBaud).  This way the attenuation is the same as it will be for run-time PAM-3... (otherwise I don't see how the training would work usefully...)

Regarding last presentation today (Tingting Zhang), it is my understanding that of coarse PAM2 needs 4 dB less S/N but at 500m the signal attenuation is much higher than for PAM3. Is that considered ?
Because of time constraints I withdrew this question today.
