asterisk users - Jan 2006 - TE405p -- loopback for the phone company?

Feeling once again like an idiot, I come to the list for help...

While my carrier (MCI vi PRI, fwiw) was trying to diagnose a problem, they asked
me to put my interface in loopback -- and I
couldn't figure out what they meant or how to do it.  I've plugged a
loopback *connector* into my 405p and tested it internally, but
they wanted something that, apparently, looped back _their_ signal.

What the?

I got zttool running and selected "loop" on the interface, but it
didn't seem to do what they wanted (nor could I tell that it did
anything at all).  Many googles for zaptel and loop didn't turn up anything
useful.

Yeah, I tried to do that before too but it didn't do anything.  It must 
not support all switch types or something.  The best you can do probably 
is to loop it at another place, but it gets rid of testing the equipment :(

Remote loopup isn't supported either.

This is a bug that needs to be fixed; currently the dual-/quad-span 
drivers to not respond to remote loop-up requests, nor do they have any 
mode to loop data back towards the network.
