Is this supposed to be normal (possible ADSL line issues)?

Do you know to which exchange(area/name) you are connecting to?

The noise on my line would drop to horrible levels at random intervals, like last night somewhere around 6pm all just went south and the Noise went below 6 and just stayed there for 1-2 hours.

Phoned telkom and had the port reset, still no luck after some time we logged a fault for a Techy to come check out the line and hopefully maybe resolve the issue.

According to the technician my exchange should be the one in Wilgehof in Bloemfontein.

Two weeks ago I had absolutely no problems with desynchs for a whole week, then the Sunday night of the following week I had continous desynchs up until Sunday night from 7PM. Then I had no problems until 16:15 this afternoon, when the desync problem reappeared. And this was the same day the technician called to say they had made another change to the ports to see if it solves the problem.

Maybe we'd better check all the lines in my house (can one faulty line screw up all the lines in the house BTW?).
