Crud - I hate replying to my own messages.  But I forgot to add something:

If you are using Paradyne FrameServer DSUs, you have another thing to worry
about.

They tend to do auto-negotiation of LMI out their WAN side and Cisco LMI
towards your router.

With this setup, you are getting your LMI from the DSU, not the switch.  So
if a DLCI goes down, you can't necessarily see it.  This is because the
FrameSaver is "intelligent".  You can configure a fake DLCI between just you
and the DSU so that you have IP connectivity to the unit for support.  So in
reality, you can pretty much ignore the stats on the router interface, and
will need to get onto the DSU itself to find out what is going on.
