Hello and welcome to LQ !
This looks like a synch bin file problem.
If you are using the default synch file, you'll need to download the rest from the eciadsl website. It is a tedious process, I know, but you'll need to try every file in turn to see which one suits your modem and ISP.
Also, there is troubleshooting file that comes with the eciadsl package, so you might want to look at that as well ...
Hope this helps.
