Restriction filters
Restriction filters can be used to restrict the numbers that may
be dialed on any external line within your Norstar system. Up
to 100 restriction filters can be created for the system.
A restriction filter consists of up to 48 restrictions with
associated overrides.
To restrict dialing within the system, you can apply filters to:
•
outgoing external lines (as line restrictions)
•
telephones (as set restrictions)
•
external lines on specific telephones (as line/set
restrictions)
Restriction filters can also be specified in
Restriction
Service
, for times when the system is operating according to
a Schedule. See
Services
on page 381 for more details.
Dialed digits must pass both the line restrictions and the set
restrictions. The line/set restriction overrides the line
restriction and set restriction. Refer to the following diagrams.
