Why don't your span numbers match? 1-4 but you have 3-6 in your .conf.
Have you tried to loop the ports or spans back to another port?
Set two ports for cpe and the other two for net, then crossover cable
to connect cpe to net. Spans should come up and you should be able to
simulate the telco and test everything out in both directions.
Finally, call Digium and your telco if you are able to do the above
with no problems.
Thanks,
Steve Totaro
