Re: [802.3_EPOC] Action items for September 2012 meeting
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
