(ASCEND) Max 200 \ calls fail with code 050
We've got a pair of Max 200s with four bris each forming a bridge from
our campus network to an outlying office. The bris at the local end
are in a UCD group and the remote end dials the UCD pilot number. Min
channels/base channels is set at 2 and it brings up the other channels
as needed. We're running 5.0Ap13 at the moment.
Aside from a few problems with one end freezing up, which upgrading
one end to 5.0Ap20 seems to have helped, this has worked for us. We'll
be upgrading the other end to 5.0Ap20 soon.
Recently, we've noticed that we're unable to bring up more than 2,
sometimes, 3 channels at a time. Even with 100% ALU and CLU, no more
channels come up. The two channels that are up are on different bris,
so I don't think any of the bris are down. The error reported when
the remote end tried to bring up additional channels is "cause code
050". We tried increasing Min channels/base channels to 3 and it
remained at 2 channels. I left it like that overnight, and it had
come up to 3 channels by this morning, but now its back down to 2.
Here's the syslog:

I looked up cause code 050 and it says: "Requested facility not subscribed."
What does that mean? Is that a telco problem? We've certainly got free
channels to bring up since the two or three that come up are spread across
multiple bris. Any advice on what to tell the telco, if it is a telco
problem?
