The BE portal to view/set DLSAM port settings is currently down. We have reported the problem and are awaiting a fix.
It's an unplanned outage affecting BE's systems. They currently don't have an estimated fix time.
The DSLAM port interface is now back up running.
BE have not informed us that it is working.
We are chasing to find out what caused this to go down and what can be done to make it more resilient.
