They are a little "old" but if you are willing to chance a few pounds, try to get an unused 2wire2700. They tend to hold sync on long lines and give excellent performance even when noise pushes the SNR down.

Ebay

Just out of interest: will that BT 2700HGV 54 Mbps 4-Port 10/100 Wireless G Router (2Wire 2700HGV) work on a G.992.5 annex A (ADSL2+) connection? And could one force a G.992.1 annex A (ADSL1) connection with it for improved speed and stability if on a long line where loop loss is high, e.g. a ~55dB downstream attenuation?

They will work on an ADSL2+ connection but not sure about forcing it down to an alternate version - I moved to VDSL 2 years back and cannot remember if there is an option as options disappear when it is used as a WAP.

Cheers - I know a few folks on long ADSL2+ lines who may benefit from using a 2Wire even if they can not force ADSL1 or ADSL2

Get one from ebay and try it on their lines ... On most, if not all lines that I have used them on, there has been an improvement.

Once it holds a signal it will try damn hard to keep it. I had one that stayed up for well over 6 months and in that time the SNR dropped to 0 regularly and even went negative for short periods but it continued to hold sync.

Will do

It will work with ADSL2+.

If a modem doesn't support ADSL2+ the MSAN will backtrack and attempt to use ADSL2, and then ADSL1 until any one of the modulations are supported.

Also if the line is long enough and meets the trigger requirements, the DLM should automatically put you onto G.DMT after a certain amount of time. You could alternatively ask your ISP whether they can put an order through for standard ADSL.

Would that apply to full LLU also? One of my friends is on TalkTalk LLU and I don't think we would want to contact phone support or even the forum about a change in modulation

The backwards compatible bit should be, but not sure about the DLM. If memory serves correct, BT Wholesale use their own custom DLM which is different from LLU Providers who do not use BT Wholesales' MSANs.
