5.36.1. Introduction 
The Virtual Numbering – VNR feature in OpenScape 4000 supports
:
- the multiple assignment of station numbers,
- the configuration of overlapping station numbers with different lengths (dependent on DPLN groups).
Multiple virtual nodes must be created for this in the OpenScape 4000
(the physical node). These are defined with node number and node code.
The station ports configured are each assigned to one of the virtual
nodes. The station number of a station port is now only unique within
the virtual node.
The unique identification of a station within the physical node is
only possible with the combination of the node code and station number.
