Re: [EFM] Re: OAM - To side-band or not to side-band

According to Webster, deterministic comes from determine which means 'to
fix the boundaries.'  Hence, setting a minimum and maximum is quite

Nothing we could do would operate on 'any specific granular time frame',
for a time frame can always be chosen which is less than 1-bit time.  I
know you have time frames you find desirable - other folk have other
views on desirable time frames.   Time frame granularity is certinly one
of the differentiators between the OAM transport proposals and should be
considered by folks when making their evaulations of the transport

I'm completely unclear on what we approach 802.3ah OAM will not be
