While systems 2 and 3 have three routes, they contain the same trunk group. This
is because calls with system 1, system 2 (or 3) and the public network as their
respective destinations are routed via the same lines. If at a later date systems 2
and 3 are connected with their own lines, simply create new trunk groups and re-
assign the routes accordingly. All the rest remains the same; more importantly,
you do not need to change the configuration of the network subscribers (PISN
subscribers).
Settings for the Routes to the other Systems
All the call numbers of calls within the network are network-internal (PISN-inter-
nal) numbers. As such they have two special properties:
• They must comply with numbering plan identifier PNP.
• They do not have to be checked by an external digit barring.
These properties are set in the configuration to the routes:
1. In system 1 select the settings for routes 1-6 and 1-7:
– Numbering plan identifier (NPI) = PNP
– Digit barring = no
2. In system 2 select the settings for routes 1-5 and 1-7:
– Numbering plan identifier (NPI) = PNP
– Digit barring = no
3. In system 3 select the settings for routes 1-5 and 1-6:
– Numbering plan identifier (NPI) = PNP
– Digit barring = no
Settings for the Routes to the Public Network
All the call numbers of calls to the public network are external numbers. As such
they must
• either comply with numbering plan identifier E.164 or
• be preceded by an exchange access prefix.
In addition they should be checked by an external digit barring if required.
