"No ATM activity detected on your DSL line"

We've been having sooooo many problems with our Broadband connection at work and all because Be* Broadband are totally incompetent and utterly, utterly useless. Also they appear to have outsourced all their call centers to somewhere in Poland because the phone line is terrible (really great for a telecommunications company!!) and all their staff speak with such thick accents that it's often hard to understand what the hell it is they are saying and although their English is very good, a 100 times better than my Polish or whatever their mother tongue actually is, it's not without mistakes that just confuse matters further.

Anyway all had been working and then all of a sudden one day it wasn't. Looking at the modem that they supplied the DSL and Internet lights were permanently off. So we phone them and they test the line and say the line is okay and we go through a few basic "can you check this" kinda questions, replace filters, cables etc. In the end they seem to think that it must the modem that's failed so they send us a new one.

New one arrives, plug it in, same thing. Back on the phone to them and yet again they test the line, which is okay, go through some basic checks and say that it must be down to BT and that perhaps BT changed the phone number without telling us (I kid you not). So they organise for BT to come out and charge us £150 for the pleasure who test our wiring and say that it's all fine and that the fault must be with the modem.

So back on the phone to Be* and yet again we go through the same rubbish questions and they say that they will send an engineer out.

The engineer never arrives!

So back on the phone to Be* again, yet another round of pointless questions and again they say they will send an engineer out.

The engineer never arrives.....again!

So, you guest it, back on the phone, same rubbish questions but now they say "oh but the first engineer fixed it" Huh? How could they have fixed it when 1) they never arrived and 2) and this is a big tell tale sign, it's still not working? "Oh, well we need to test the line again".

This goes on for a few more days. I then phone Be* back and again go through the same pointless questions and then finally someone looks back through the engineer reports and says "oh the 1st engineer said that a piece of our hardware at the exchange wasn't working, but it doesnt say if it was fixed". How incompetent can Be* be? An engineer identifies a fault but then nothing is done about it, for nearly 2 weeks and it's ONLY when the customer complains enough does someone go "oh, should we have fixed that?"

Anyway, it appears that this faulty bit of kit has now been replaced at the exchange because we now have a nice solid green DSL and Internet lights on the modem. However we still can't connect to the fekking Internet!!!!

When I log into the router and get it to check the Internet connection it says that the DSL is connected but that there is "No ATM activity detected on your DSL line" and no activity on Ethernet either.

I really, really can't face phoning Be* again so does anyone know what the hell "No ATM activity detected on your DSL line" means? Does this still indicate a problem at the exchange (maybe they are still working on it) or could this be a modem configuration issue at our end?
