Pat,
If you configure the ilmi pvc then you can see the nsap address. I don't
know of any other way to get it. It you are told of PVC connections to
other routers but are not given the PVC vci/vpi info, the is an
autodiscovery command that will help find them. I don't remember the
command, but I will see if I can find it.
