Re: [802.3_EPOC] Action items for September 2012 meeting
Alex,
My intention was not to open the whole discussion on what's in the scope and
what's outside the scope. I would just like to complete the task at hand
that is collect the list of terms we need to specify. Any side discussions
are welcome as long as they serve the purpose of bringing us closer to the
end goal. Otherwise, they are just distracting.
I would suggest that if you believe that discussion on the OCU topic is
needed, you start a separate thread but let me finish the task I took on
Thursday. If you have anything to contribute to this discussion, I would
welcome your input. Flaming however, is not welcome. Let's keep the
discussion focused.
Regards
Marek

In the course of this week's discussions on the OCU and TDD (and the
attempts to shut them down), I could not help be reminded of a quote from
Ralph Waldo Emerson's "Self Reliance":
"A foolish consistency is the hobgoblin of little minds, adored by little
statesmen and philosophers and divines. With consistency a great soul has
simply nothing to do."
Why the insistent focus on the things that we *cannot* do? Things like OCU
specification, TDD inclusion, etc.? Why not turn our attention back to
things we *can* do, on time and on budget?
Does anyone really think that the specification of the EPoC PHY (and the
interests of the N. American and Chinese cable industries) would not be
helped by a robust discussion of the OCU and the overall OLT-to-CNU system?
Alex

Rick,
We are not yet TF - let's not get ahead of ourselves.
While I will record multiple proposals for this one term, I think you're
missing the point of why the list was distributed in the first place. I
would like us to focus on making sure that we have all terms we need, rather
than focus on what the ideal acronym is for a network element we are not
going to specify either way
Regards
Marek

Marek, Jorge, Hal, the TF (YES!) members,
I would like to propose the following term for consideration:
- OCN (optical coax Node)
- FCN (Finer coax Node)
I believe 'Node' is more appropriate to refer to such a remote field device
in an HFC plant.
With 'Node', it also clearly differentiate from CLT and CNU, thus we have
- CLT as a 'Terminal' where all EPoC protocols must be 'terminated' on one
side
- OCN (or FCN) as a 'Node' where it provides physical or MAC layer
processing between CLT and CNUs WITHOUT affecting IOP
- CNU as a 'Unit' for subscriber access to an EPOC network
'Terminal', 'Node', 'Unit' would distinguish the functions better.
Also 'Node' does not contain potentially offending characters and can refer
to either a repeater, a bridge, or anything in between or even above.
I would also like to comment that in certain network scenario, this remote
device may not exist - where CLT is in the node location for example.
Best and have a good weekend
Rick
