I don't think this is correct. The OP below said that he put the loopback
on himself, as a test.

No, you can't loopback a port to itself with Asterisk running, because
it will always appear to be talking to the same kind of device as itself,
whether it is NET or CPE.

What is more likely is that you need a crossover cable between your Digium
card and the modem. Make up a crossover cable according to the instructions
