RE: [10GBASE-CX4] SIGNAL_DETECT
My $0.02:
I do not see how SIGNAL_DETECT can be specified in terms of a receiver
sensitivity threshold when, based on data presented, the receive eye will
likely be completely closed.
Even if not completely closed, there is a high likelihood that the receiver
min threshold will be so low that, even after EQ, you will not be able to
accurately apply a level test to determine whether there is adequate signal
to make a decision.
I believe the right approach lies in using the state machines provided in
Clause 48 to declare a Local Fault condition.

Howard,
Please find attached the text proposed for SIGNAL_DETECT.
I found the most appropriate text for our applications in clause
39 (1000BASE-CX).
Regards, Petre
