Cisco SR520 issues

Hi all,

I have been working on a customer site for quite some time now and keep on running into a variety of issues with their connection to the internet.  The Cisco SR520 is currently attached to the ADSL service, it stays up and running for a random ammount of time.  It disconnects sometimes 3 minutes, sometimes 8 hours but it still keeps on disconnecting. 

If I plug in the old Dreytek router the service stays connected but still it will drop after say 24 hours.

I'd just very much appreciate it if someone could look over my config below and tell me if there are any obvious mistakes which could be effecting the service;

Many thanks in advance.

James
