CRC errors are (basically) data corruption.

I will agree that your line is piss poor, might be an idea to get BT to check it out for you.

I have done a few times and they run the test from there and say there is nothing wrong with it and that all their tests show it's fine...
Strange then that I have been offline all night because the line wouldn't sync!
