Improving SNR?

I have read various posts here regarding wiring up the adsl equipment. My SNR was around the 6.8db mark, and I kept losing my connection, and had keep switching my router off and on to connect again.

However, on my master BT socket, I unscrewed it and plugged my router directly into the BT "test" socket, and this has improved my SNR by about 2.5db to about . It now syncs at higher speed, around >15000 (opposed to around 12000 previously) and so far hasn't dropped the connection at all (so far).

So my question is, if i got for example, an ADSL master faceplate such as the XTE-2005 would I expect to see a further improvement to the SNR/sync speeds and ultimately to my downloads, which are around the 12.5Mb mark (on Sky BB Max 16Mb service)

if i got for example, an ADSL master faceplate such as the XTE-2005 would I expect to see a further improvement to the SNR/sync speeds

Unlikely to improve [further] on the figures you get when plugged into the 'test' socket, although some users have reported small increases, but for the sake of

Do you have to move your router to access the faceplate socket ? You will probably only notice a difference if you keep the ADSL wiring short. I moved my modem next to the XTE-2005 faceplate, and ran a longer ethernet cable back, and that improved my SNR.

No i saw an improvement just by putting socket straight into "test" socket.

I was enjoying disconnection service for about 9 hrs, but sadly it dropped again!

Do you think it is because my SNR is a bit low or is it something else, can SKY set the db and their end of things?

I would expect Sky to set a target SNR margin. Could you post your attenuation, margin and speed stats.

ADSL Link Downstream Upstream
Connection Speed 15323 kbps 766 kbps
Line Attenuation 35.0 db 17.4 db
Noise Margin 9.8 db 12.9 db

not bad, double the speed I get for a similar attenuation and the margin of 10 dB is quite good.

i have just replaced my master faceplate with a filtered version and run a new extension with both filtered (for a phone) and unfiltered (for adsl) through different twisted pairs in the same cat5 cable to one special secondary box with 2 outlets on one faceplate an RJ45 module for the adsl and a normal phone plug module for the phone by the computer.this is about 5 mtrs from the master box


its a very tidy way to do it and my snr is now exactly the same as it was from the test socket in the bt master box. (with all the wiring hard wired in there is less chance of bad connections)

if you want to see the way its done and where to get the bits

very usefull info that helped me no end.

they also explained about the bell wire on terminal 3 that most modern phone equipment doesnt need these days that can act as an ariel and so be a source of noise.
(i left mine disconnected on the extension with no probs to the phone )

the trickiest bit was shortening the RJ45 patch cable to about 12 inches
i'm not sure you are supposed to take those plugs apart and reconnect but i managed it eventually as i didnt want any extra cable hanging around near the router picking up signals from all the other equipment nearby.
try to make sure your cable routes are away from things like transformers and mains cables as much as possible as well

my snr is still variable(worse at night ) but i now know its all down to my overhead phone lines outside probably picking up AM radio interferance and not my dodgy cheapo phone extension cables with adapters and filters hanging out by the phones etc that get kicked and sometimes come out.all gone now
i hope this helps someone else as it took me a while to realise it was possible to do this and then find out the right way to do it.
(dont forget to ask for the new longer screws if your original faceplate has machine screws holding it on on older BT master boxes)
current stats for my line
SNR Margin 14 / 12 dB (approx 2db better than before)
Line Attenuation 28 / 12 dB
Data Rate 8157 / 618 kbps
