6.1.8 Numbering
There are two methods for setting up the numbering plan of a private network:
• Numbering with blocks (shared numbering plan)
• Numbering with regions
6.1.8.1 Numbering with blocks (shared numbering plan)
Fig. 3.63: Numbering with blocks (shared numbering plan)
The numbering range is divided into blocks. Which are distributed among the sys-
tems. This method is preferable as the user does not have to know the network
topology. He can reach any subscriber in the network simply by dialling the inter-
nal number, regardless of which system he is connected to. Drawbacks of the
method:
• When networking existing systems the existing numbering plans sometimes
have to be adapted. Subscribers do have to be allocated new numbers.
• The number of network subscribers is limited by the number range available.
The page 689 contains an implementation example for this method.
