Folks on here seem terribly knowledgeable about attenuation and SNR values and all that jazz, so I thought it'd be good to ask here about whether I should pursue Annex M to get a better connection. I upload a reasonable amount, including large sets of photos, and a recent visit to my brother's house (who has fibre) has made me obsess about my connection all over again... I can't get fibre, as i'm on an Exchange Only line, and while I did spot them installing new cabinets outside the exchange (which is just up the road) there's been no progress on Fibre availability to my line.
Here are the values from my router:
DSL Status: Connected
DSL Modulation Mode: ADSL2+
DSL Path Mode: Interleaved
Downstream Rate: 18869 kbps
Upstream Rate: 831 kbps
Downstream Margin: 6 db
Upstream Margin: 7 db
Downstream Line Attenuation: 11 db
Upstream Line Attenuation: 3 db
Downstream Transmit Power: 9 db
Upstream Transmit Power: 15 db
And a speedtest: http://screencloud.net/v/gqOX
So, the download speed's not bad, but I could really do with some better upload. My questions are:
1) Based on my current speeds and attenuation data, is it worth bothering?
2) How much download speed would I be sacrificing, and for what kind of boost to upload?
3) Is there anything else I could do (short of kidnapping an OpenReach engineer) to get a Fibre connection? I contacted some Scottish Government agency in charge of fibre rollout, but not much joy there. Would getting a new line from BT likely help?
Thanks in advance for any wisdom
