[c-nsp] atm0 going down every five minutes (DSL: Defect: LOS LOF LCDi: retraining)

[Elmar Pigeaud]

Called them, they tested the line: no problem (they never heard of SELT
however). Other modems have no problem whatsoever (can't try another
cisco...). The line should be very short, because it is connected in our own
street and I get the full 8mbit.

I can try to have them test the line more than they did now, but as other
modems have no problem on the same line, I don't think the solution will be
there.

Any other suggestions?
