5.36.3.2. Network Integration 
- An openly numbered network is basically a network with at least one VNR node (OpenScape 4000 with the feature "Virtual Numbering" active).
- The following measures are necessary for closed numbering:
- The usual KNMAT entries that are needed for open numbering in an OpenScape 4000/HiPath 4000 network are required in all OpenScape 4000 systems in the network
- In addition to the KNMAT modification in the systems directly connected to the VNR system, an OUTPULSE must be configured in the AMO LODR with the node code for the VNR system.
- Evaluations should be performed to check the effect of open numbering on existing applications and if any adjustments are necessary.
- Adjustments may be necessary in call data recording.
- In VNR systems, all virtual nodes that have the same E.164 station number must be assigned the same node number network-wide. It is not necessary to adapt the existing standard OpenScape 4000/HiPath 4000 network. In the case of network expansions and significant modifications, this concept should be adopted with a view to achieving a clear network structure.
