Numbering in Networked Systems 
 
In private networks, station phone numbers, seizure codes, and service codes are assigned according to a numbering plan provided by the customer.
HiPath 3000 supports the following numbering schemes:
 •   Closed numbering
Requires that all station numbers are unique within the network. Each station in the network can reach another station by dialing their phone number.
 •   Open numbering
This means that stations are identified using a node number (PABX number) and their station number. Stations in different nodes (systems) may therefore share the same number.
 •   M.164 numbering
The numbering can be open or closed. A node number is not required. The stations can be reached via their public number, i.e. their E.164 number. Each station is represented by its E.164 number which can be displayed optimally. The advantage of the E.164 numbering is that the station can be reached via a number and no node number is required.
The same numbering plan must be selected for all networked systems (nodes).
