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.
