Each system has its own numbering plan. The numbers always start with 200.
If the subscribers of one system want to call a subscriber in another system, they
dial the corresponding prefix followed by the subscriber number. For example, a
subscriber of system 2 wans to obtain the number 210 in system 3. He dials
60210.
A separate region has to be created for each system (similarly to the regions in the
public network). To this end we need to specify the regional prefix for each sys-
tem:
1. Specify the region for each system:
– System 1: Region 40
– System 2: Region 50
– System 3: Region 60
2. In each system configure its own region prefix under the basic settings:
– In System 1: Own regional prefix: 40
– In System 2: Own regional prefix: 50
– In System 3: Own regional prefix: 60
The further procedure depends on whether region selection is implemented via
PISN subscriber or via local area network (see also the explanations on Page
3.102). In the following we shall be looking at both types.
Region Selection via PISN Subscriber
The regions of all the other systems are now entered in each system. To do so cre-
ate numbers in the PISN subscribers category in the numbering plan. There you
can create either individual numbers or number ranges by specifying the range
with "XX". Each "X" corresponds to one digit place.
1. In system 1 create the following PISN subscribers:
– One PISN subscriber with the number 50XXX (region of system 2)
– One PISN subscriber with the number 60XXX (region of system 3)
2. In system 2 create the following PISN subscribers:
– One PISN subscriber with the number 40XXX (region of system 1)
– One PISN subscriber with the number 60XXX (region of system 3)
3. In system 3 create the following PISN subscribers:
– One PISN subscriber with the number 40XXX (region of system 1)
– One PISN subscriber with the number 50XXX (region of system 2)
