Underground ducting for cables is far better than overhead external cables as they don't fall into the environmental impulse noise gap as such ... but even then what becomes more difficult to handle is any crosstalk in the bundles. And why after much expense on same ... BT have implemented G.INP (Phyr technology). Which presently is only running downstream.
Interesting comment you have made.
It's only by deduction that the user can determine if g.inp is enabled.
From the broadband availability check, my cabinet details show that "retransmission" is present, which is presumably related to g.inp.
You can't find a direct, definitive statement:- "g.inp is enabled".
Also transpires that the HH5a, (my previous hub) could not support g.inp fully. Hence the improvement with the HH6.
(I must be one of the fortunate few to have had, or have reported, success with the HH6).
Downstream noise margin is now at 1.8db - now 3 days.
The following links gives a clue as to when this will be happening:
Can't wait until Monday or sometime before September!
Good post, thank you.
Being a cynic I could suggest a marketing slant.
The overall stats across the country will, I think, show an increase in speed of some sort.
Plenty of room for advertising.
G.Inp will have absolutely no impact on a perfect line, it doesn't increase speed, it restores speed lost to error correction. Throughput will be improved if G.Inp is implemented on a bursty noisy line as the error correction will be performed at the physical layer as and when needed rather than continuously at the TCP layer as before.
