     Sorry for all of the junk on the end of my last message, it was
supposed to be a MIB file!  Anyway, the definitions for the 2 missing traps
are:

demandNbrLayer2Change NOTIFICATION-TYPE
        OBJECTS {
                ifIndex,
                isdnLapdOperStatus
                }
        STATUS  current
        DESCRIPTION
        "This trap/inform is sent to the manager whenever the
        D-channel of an interface changes state."
       ::= { ciscoIsdnMibTraps 3 }

        OBJECTS {

                ifIndex
                }
        STATUS  current
        DESCRIPTION

         an incoming call request is rejected with cause

         code number 44.

         isdnSignalingIfIndex is the ifIndex value of the interface
         associated with this signaling channel.

        "
       ::= { ciscoIsdnMibTraps 4 }

Hope this comes through better than the last time!
