If VNR is not activated only unique station numbers with a maximum of 6 digits are accepted. The numbers must be independent of the DPLN; similar numbers will not be accepted. Virtual nodes are also independent of the DPLN.

If you wish to switch to the mode "VNR activated", you must execute the AMO ZANDE and set the VNR flag to YES. In CM, the display of station numbers is taken from the AMO.

If the user activates the global flag in a particular OpenScape 4000, the display of the relevant station numbers in the OpenScape 4000 Manager database is no longer applicable. The display in the Manager/Assistant depends strongly on the display in the AMO. If the display in the system changes, an upload with the new displayed numbers must be performed without delay in OpenScape 4000 Manager/Assistant. Following modification to the VNR flag, Upload All must be implemented. With Upload All, all station numbers are returned as 12-digit numbers including the access code of the virtual node (VNAC). In CM, the display of all station numbers loaded by the relevant system is adapted. DPLN-dependent virtual nodes can be configured; identical and similar numbers are permitted.

With the current implementation, routing cannot be correctly performed when systems with and without VNR are operated in one domain. However, there are current scenarios that support this option.

As the current Manager implementation only supports routing in domains where VNR is either globally activated or globally deactivated, new V4 systems where VNR is activated should be assigned to a separate domain.

Customers can continue to enter abbreviated numbers when configuring station numbers. During saving, the numbers are then automatically extended. Once saving has been successfully completed, the numbers are shown in full.
