Dialing plans
Dialing plans allow users to enter consistent dialing 
information to call other systems, or out to a public network 
through another system. The type of network determines what 
kind of dialing scheme is required.
The Norstar system has routing features that allow you to set 
up a transparent dialing plan with other systems in a public or 
private network. In a private network, you can choose to use 
either a uniform dialing...

• you create access codes that are routed out on auto-answer 
lines connected to the other sites (Access Codes and Call 
Routing)
• a telephone can be reached using the access code and the 
telephone number, regardless of where the call originates 
in the network
Calls routed over private networks using UDP require a 
private DN length, since each node requires an identification 
code in the dialing string, which makes the DN length...

For example, imagine that you have a system in a network of 
three offices such as New York, Toronto, and Santa Clara.
If there is no routing, callers would have to dial this way:
• A Norstar user in New York would have to select a line 
pool and dial a number such as 1-416-555-3227 to reach 
telephone 3227 in Toronto (416). 
If there is routing:

In the table, 4 is used as the initial digit for the Coordinated 
Dialing Plan (CDP), but 5 or 6 could also be used for this 
purpose.
For PRI you need to define a route with a routing code 
(destination code), then assign that code to the telephone.

In the above example:
If a user in New York calls Toronto within the network, they 
dial 6221. The local Norstar checks the number against the 
routing tables and routes the call according to the destination 
code 6, which places the call using Route 001. 
There is no DialOut change to the number from New York, so 
the call appears on the auto answer line on the Norstar in Santa 
Clara as 6-221. 
Because 6 is also a destination code on the...

Dialing plans with shared line pools
Installer password required
Using routes and destination codes is a powerful and efficient 
way to create a transparent dialing plan. Line pools offer an 
alternate method of creating a dialing plan or supplementing 
the routing and destination codes. This is the type of dialing 
plan you would create for tandem networking between two or 
more Norstar systems.

example, system A, B, and C are all within the same area code. 
System A has a line pool to Santa Clara, System B has a line 
pool to Montreal, and system C has a line pool to Miami. 
A Norstar user in system A can reach Miami by calling system 
C and using that line pool to Miami.
To simplify access between Norstar systems, all line pools that 
go to the same destination should have the same line pool 
access code. For example, system A and...
