Notes on Open Numbering in a HiPath 3000/5000 Network 
 
In contrast to standalone systems, a HiPath 3000/5000 network performs call number evaluation in a number of stages. All station and group numbers for the relevant HiPath 3000 systems (nodes) are kept on the HG 1500 boards and subject to digit analysis. The Feature Server sends the IP addresses of the relevant HiPath 3000 systems to the HG 1500 boards. The Feature Server also assigns every HG 1500 board a call number table in which all call numbers of the other HiPath 3000 systems are saved. This means that every call number dialed can be uniquely assigned to a node. These call number tables are also known as CAR (Call Address Resolution) tables. The call number tables can be displayed using HG 1500's Web-based management (WBM). Changes made to tables with the WBM can impact the digit analysis functionality and are not permitted. The CAR tables are updated and overwritten by the Feature Server after every administration activity.
Internal call numbers can be assigned more than once in a network using open numbering. However, to enable unique call number evaluation, every HiPath 3000 system is assigned a unique node number. A station in node A always dials a station in node B by entering the node number + internal call number.
The "Open numbering" system flag in HiPath 3000/5000 Manager E must be set for every HiPath 3000 system involved. This flag must be set to permit the administration of the node number.
The node number (Settings/System parameters.../Flags: Node number) and the incoming PABX number for route 16 (HG1500 route) (Settings/Lines / networking.../Routes: PABX number - incoming) should be identical for every HiPath 3000 system.  
In HiPath 3000/5000 V7 and higher, it is possible to administer the node number of each associated HiPath 3000 system using HiPath 3000 Manager E, regardless of the status of the system flag "Open numbering scheme".
In HiPath 3000/5000 V7 and higher, the node number (Settings/System parameters.../Flags: Node number) and the incoming PABX number for route 16 (HG 1500 route) (Settings / Lines/networking... / Routes: PABX number - incoming) do not need to be identical. With an open numbering scheme only the node number needs to be administered.
