You should easily be able to put a loop locally or remotely onto an
interface with the following command ..
set interface t1-0/0/0 t1-options loopback local (or remote)
Then you should be able to run the BERT end to end with a tester.
There is a built in BERT test on the T1 interfaces, however I used this
some years ago and found whilst it gives an indication of functionality,
the actual results were a bit inconsistent on certain parameters. I
believe the functionality of BERT was designed more for the T3
interfaces, the framers on the E1/T1 PIC's are not great for the BERT.
