Your config looks reasonable to me. Either the telco has not set it up with NFAS
at all or NFAS the way you expected (which is a very real and common
possibility), or your version of IOS is broken in this regard (which is also
possible, considering the tracebacks).
You should not expect to see a Serial1:23 interface. A NFAS group is treated as
exactly one configurable element, controlled by a single D channel. You don't
need to configure the backup D channel. It assumes the same config as the
primary if it becomes active.
If you want further troubleshooting help, send us a "show version" output. Also,
send the output of "debug isdn events" and "debug isdn q931" as these PRIs are
coming up with the NFAS config - i.e., shut down the PRIs, turn those debugs on,
reconfigure them, no shut them and record the output.
You may want to open a TAC case and ask about those tracebacks. It's generally
not a good thing to be getting tracebacks. You may be running a bleeding-edge or
broken IOS that you shouldn't be.
