Ummm. I have my doubts. You may get G.INP, but no significant speed gain.

Well I'm not too fussed to be honest... just want the best stability and consistency from the line possible..

I was going to upload about 15-20GB's worth off stuff to One Drive and a few FTP uploads too while at work but PC went into standby so looks like I'll be running them through the night

Attenuation seems high for that length of line.

Max: Upstream rate = 21369 Kbps, Downstream rate = 64028 Kbps
Bearer: 0, Upstream rate = 19999 Kbps, Downstream rate = 64031 Kbps

Down Up
SNR (dB): 6.2 6.9
Attn(dB): 17.2 0.0
Pwr(dBm): 14.0 7.2

Line length 500m +/- 20m.

All copper, tested to death previously due to very severe issues so very clean; very, very, very heavy crosstalk.

Aye, I thought that too... I reckon Openreach Voice Engineer couldn't be arsed to do a good job and just grabbed a pair down the road that might of been unused due to a fault possibly...

Oh well, take what I can get at the moment, won't be here to much longer anyway.

When G.inp got switched on on my line, I gained about 6Mbps! I was syncing at around 60000Kbps before that. Here's my stats now on a 350m (according to BT but attenuation suggests it could be longer) line:

Downstream Upstream
Line Coding (Trellis) On On
SNR Margin (dB) 6.3 6.1
Attenuation (dB) 19.4 0.0
Output Power (dBm) 12.6 7.4
Attainable Rate (Kbps) 66252 16665
Rate (Kbps) 66212 16703
B (# of bytes in Mux Data Frame) 243 237
M (# of Mux Data Frames in an RS codeword) 1 1
T (# of Mux Data Frames in an OH sub-frame) 0 64
R (# of redundancy bytes in the RS codeword) 10 16
S (# of data symbols over which the RS code word spans) 0.1173 0.4534
L (# of bits transmitted in each data symbol) 17327 4482
D (interleaver depth) 8 1
I (interleaver block size in bytes) 254 127

59.1meg sync on a 59.7 estimate I dont think anyone will treat that as a fault.

is the upper estimate 80th percentile?

No wonder my engineer looked gutted after my pair swap, I was happy to get back above 70mbit but he seemed shocked as if he was expecting the full 80.

I know, it's the reason I've never really bother trying to report it..

In reply to a post by Chrysalis:

Yes.
