2.2 The System's Numbering Plan
The system's internal numbering plan is the numbering plan used for a stand-
alone PBX or a PINX in a private network. The numbers entered in the numbering
plan are used both to dial up call destinations in the PBX 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.
