Any comments on these line stats

Just moved house and now on Talk Talk LLU ADSL2+, but via Uno Broadband.
It's been a couple of weeks and no real problems so to speak.
My router (Asus DSL-N55U) reports the following;

Modulation : ADSL2+
Annex Mode : Annex A/L
SNR Up : 12.7
SNR Down : 11.6
Line Attenuation Up : 6.9
Line Attenuation Down : 17.0
Data Rate Up : 903
Data Rate Down : 15389

From what I can gather the SNR Down seems decent and suggests I could squeeze some more Mbit but the attenuation I'm not sure on.
Would I contact Uno to get a tweak?

Cheers

Basically you have a very short line.

Suggests a range to be expected of 18.8 to 20 Mbps for the attenuation, but based on your stats a 6dB margin might take you to 18.6 Mbps

Same account type as yours (?) at uno - pro TTB SMPF

These are my current stats (TG 585 v7 router):

DSL Type: G.992.5 annex A
Bandwidth (Up/Down) [kbps/kbps]: 1.022 / 13.420
Output Power (Up/Down) [dBm]: 12,0 / 19,5
Line Attenuation (Up/Down) [dB]: 20,5 / 37,0
SN Margin (Up/Down) [dB]: 10,5 / 5,5
Vendor ID (Local/Remote): TMMB / BDCM
Interleaved

SNRM's are probably holding your sync speeds back a bit - although you have a shorter line than me and less loop loss (attenuation) there is perhaps some noise affecting the line and the downstream SNRM at ~12dB is perhaps stopping the DSL connection from dropping.

If the line can remain stable with a downstream SNRM of 6dB then one would expect a 20000Kbps, or more, sync speed with your 17dB attenuation.
