3. 2 The System's Numbering Plan
The system's internal numbering plan is the numbering plan used for a stand-alone 
communication server or a PINX in a private network. The numbers entered in the 
numbering plan are used both to dial up call destinations in the communication 
server and to execute control functions.. Call destinations and functions are 
grouped into categories. 
The internal numbering plan:
• Assigns number ranges to the categories.
• Allocates their numbers to call destinations and control functions, making them 
obtainable and executable respectively.
As far as the call destination numbers are concerned, the system's numbering plan 
is a PNP-type numbering plan.
