i will start out by stating that the fact that your modem reports the line stats in 0.1 format threw me for a loop. fortunately dividing by 10 gets the real numbers.

to save time, i'll print out the numbers

snr margin downstream: 7.4 dB
snr margin upstream: 15.9 dB
attenuation downstream: 11.0 dB
attenuation upstream: 4.3 dB
output power downstream: 0 dBm
output power upstream: 11.3 dBm

Line rates (+-.5Mbps) [15% overhead calculated]:
Max line rate: 22.5Mbps
Actual line rate: 17.4Mbps

i must say you have a really good line there, although your downstream snr could be a bit higher, but if it's constantly at 74, i wouldn't worry about it too much.

continuation of above post (forum kept eating it):

snr guide:
<6db: not good
6-12dB: marginal, should get line checked, but if it works, it works
13-20dB: good
21-30dB: great
>30dB: excellent
 
attenuation guide:
>70dB: no dsl
69-60dB: lowest tier dsl
59-50dB: good for up to 5Mbps
49-40dB: good for up to 7Mbps
39-30dB: good for up to 10Mbps
29-20dB: good for up to 15Mbps
<20dB: you can get whatever you want, usually
 
power guide:
0-8dBm: great
9-14dBm: fair
15-19dBm: poor
>19dBm: maxed out, not usually a good thing

how to get higher snr

Margin is signal to noise ratio and is dependant on speed, cable length, noise pickup, etc.

There is nothing you can do about the phone line between the phone company and your residence but if something within your residence is degrading DSL you can correct.

Temporally connect your modem to the phone company NID test jack. The NID is usually near the electric meter but could be elsewhere. If stats are better - either faster sync speed higher margin something within your home is degrading the signal. DSL is adaptive so you may want to go back and forth a few time to make sure your are getting a valid reading.

My guess is that you will not see much if any any difference. You are pretty close to the Central Office and have very fast sync speed. If you do see a difference may want to install a whole house POTS/DSL splitter rather than using in-line filters on each phone. A splitter does a better job isolating DSL from Voice.

Wish I had your speed.
