6.4 Notes on Open Numbering in a HiPath 3000/5000 Network
In contrast to standalone systems, a HiPath 3000/5000 network performs call number evalua-
tion 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 Fea-
ture 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 man-
agement (WBM). Changes made to tables with the WBM can impact the digit analysis function-
ality 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 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 in-
>
coming PABX number for route 16 (HG 1500 route) (Settings/Lines / networking.../
Routes: PABX number - incoming) should be identical for every HiPath 3000 system.
