Can't use ADSL2+ :-(

[Technical Ben]

Thanks guys - I have every bit of confidence this will hold up. Within minutes the BT connection speed would always fluctuate, and there were a lot (30,000+) CRC errors on the downstream within hours. This has been up since about 12:30 according to router logs. Zero fluctuation, no errors at all - And this is with interleaving OFF (BIG yayyyyyyyyyyyyy for low latency!!!!).

I'll never know where the actual source of the problem lies, but this happened twice with separate lines connected to this exchange. Big clue right there I guess, but BT say's it's healthy...

Sadly, we wonder if BT would even help/tell IDNet. With all the power threats goodwill great knowledge and ability IDNet have, it's BT they are up against!   
It seems that the likes of Telephonica (is that right?) may not be as big as BT, but they know how to get their kit working, and working well. Which means IDNet can have it gold plated with service and quality and a setup that... ok, I might be overdoing it, but they do great when it's possible!

  I know we all love that broadband western, full of goodies and baddies (and BT play the baddie oh so well) but my experience is that ANY variety of DSL (which includes LLU), and I've tried all of them (and more), can fail to perform to its spec for a multitude of reasons not all of which seem to be remediable, and who's running it is the least influential. The only certainty is whatever works for you is good  .

Telefonica is the Spanish equivalent of BT and have operations in several countries.

They do of course have experience of operating DSL circuits in a climate that is scorchio! hot for a good proportion of the year so the copper will expand, whether this has filtered into the design of DLM on their circuits here I couldn't possibly say but they do seem to perform better on some lines (including my own).
