Unfortunately the check items can only be tested after the user's been
asked for their authentication info.

Well, the DN setting DOES do something, but it's net effect isn't anything
useful because of how it was implemented. As it stands now, an incoming
call will associate itself with the logical 'port' that has a matching DN.
It's the incoming calls that cannot find a 'port' with a matching DN
that's the problem: if there is no ports with a matching (or blank) DN it
would make considerably more sense to return a circuit busy.

Setting it up this way could have two benefits that I can see:

1. PM3 users could create different classes of service (ie. different
users:line ratios) within the same chassis (or groups of chassis)
by having different DNs.

2. This could also serve as the "soft busy" feature everyone wants. By
setting all the DNs to a bogus number on a chassis, incoming calls
would get a circuit busy, and be forwarded to the next PRI in the
hunt. Why have a new setting for soft busy when the existing
DN setting (if fixed) would provide the same functionality, and then
some?
