FYI
I have previously read about PhyR & G.INP and it was implied that they were not 100% the same.
I cannot remember where I found that information but just after a quick hunt using google I have found:
1. An App Note from
www.exfo.com (Top-two supplier in portable telecom testing). [Attached]
2. Release Notes for Firmware Release A2pv6C038q and B2pvC038r1 (Cisco 800 Router) [Attached]
3. An Introduction to G.998.4:Improved Impulse Noise Protection [Attached]
1st Two of these reference PhyR & G.INP as separate things.
3rd is reference material about G.998.4 (G.INP)
My understanding was that PhyR was a BroadCom vendor specific thing which was formalised as the Industry standard G.INP which may not be 100% the same but achieves the same end.
G.INP supports 4 framing types. (G.INP is a superset of PhyR ? ? ? perhaps)
Still not 100% sure but good info to read anyway.
