Using System features
Using alternate or scheduled services
There are three types of Services to make your Norstar system 
handle calls differently on different days and at different times of the 
day: Ringing service, Restriction service and Routing service.
Each of the three services, and the six schedules available to each 
service, are customized for you by your installer or customer service 
representative. They program which telephone is used to turn 
Services on and off, and display what Services are in use. This is 
called the control telephone.
Preventing certain calls from being made
Restriction service prevents a user from making certain kinds of 
calls from a telephone or from lines that are available at the 
telephone. The restrictions are programmed by your installer or 
customer service representative.
Making additional telephones ring
Ringing service makes additional telephones ring for incoming calls 
on external lines. For instance, all incoming external calls can also 
ring at a security guard’s telephone during the night, or calls to one 
attendant can also ring at another attendant’s telephone during 
lunch. It does not suppress your normal ringing assignment.
Changing the lines used by outgoing calls
Routing service allows you to assign alternate routes to calls. In this 
way you can take advantage of lower costs available on particular 
routes on certain days and at certain times. Both the regular and 
alternate routes are programmed by your installer or customer 
service representative.
Turning Services on and off
The master control for how different services and their schedules 
are used by your system is in programming. There are three 
settings: Manual, Automatic and Off.
