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 ring at a security guard’s telephone during
the night, or calls to one attendant can 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.
