This node code number is the code number with which a virtual node
can be reached by other nodes network wide. The virtual node code number
is provided with AMO KNDEF, parameter NODECD for the unknown numbering
plan and also AMO WABE with the DAR OWNNODE. Note: If a physical node
contains several virtual nodes, then several entries are also necessary
in the AMO KNDEF. For each virtual node number the parameters NODECD
and OWNNODE (with AMO WABE) have to be configured..
The node code is for open numbering and is modified by AMO KNMAT for
the phone number("calling numbers") modification feature.
