[c-nsp] ADSL Keeps Dropping

[Paul Stewart]

We have a customer who keeps dropping their ADSL connection to us.
We're using a 1711 router with an external modem.  We've swapped the
modem and still seeing drops... Before I call the line provider, I
wanted to make sure the router config wasn't an issue.. It's identical
to some others (minus this customer has two internal VLAN's we created
but they really don't have anything to do with DSL I don't believe)...

The log just keeps showing virtualaccess1 dropping and coming back....

Thanks for any input..:)

Paul
