HiPath node number. This field contains the globally unique number of your own PABX. This has a hierarchical structure containing different levels in Version V1.0 and later. Up to three values of the format: L2- L1- L0 can be used for numbering a system. - L2: area number in level 2 - L1: area number in level 1 - L0: area number in level 0 or node number in the old sense. If the value '0' is selected for a level, this means that the relevant hierarchical level is not being used for node numbering: '0' is equal to 'nothing' or 'level is not set'. With the help of this new node number format it is now possible to implement node numbers in networks in which - just as with dial numbers - the network hierarchy is reflected in the node numbers. The same numbering level (= number of levels set in the node number) must be used for all nodes in a network. This field will always show a three-level display with leading zeroes for levels not used for systems in Version V1.0 and later. Example: - 0-0-100 for 1-level numbering - 0-1-101 for 2-level numbering - 1-2-300 for 3-level numbering Values: 0-9 and '-' with format 22-111-000 Level 0 (000) 0-999 Level 1 (111) 0-253 Level 2 (22) 0-29 Max. 10 digits
