Feature Reference
Night Service with Outward Restriction
Night Service with Outward Restriction prevents unauthorized after-hours use of
telephones. When this option is programmed, only authorized operators can
activate and deactivate Night Service, and only authorized users can place
calls.
A system operator must enter a password to activate or deactivate Night
Service. When one operator activates or deactivates Night Service by using a
password, all consoles are put into Night Service. If Night Service groups are
assigned, Night Service is activated or deactivated for all groups and cannot be
activated or deactivated independently for each group. When the Night Service
feature is activated, enter a password before making a nonemergency outside
call. When you have entered the correct password, the system checks for
calling restrictions assigned to your extension before allowing the call.
A Night Service Emergency Allowed List of emergency numbers can be created
and can include up to 10 numbers, each with a maximum of 12 digits. Users
who do not know the Night Service password can dial only the numbers on the
list; calls to numbers not on the list do not go through unless the caller enters a
password.
One Exclusion List for Night Service can be created to exempt specific
extensions from the password requirement. An unlimited number of extensions
can be assigned to the list. However, normal calling restrictions (if any)
assigned to the extension are still in effect. Unrestricted extensions on the list
are not protected against unauthorized after-hours use.
Night Service with Time Set
When the Night Service with Time Set option is programmed, the system
automatically activates Night Service on all operator consoles at a specified
time of day and on specified days of the week. A different time of day to activate
or deactivate Night Service can be programmed for each day of the week.
System operators can still override the timer and turn Night Service on and off
manually if they prefer. If one system operator overrides the timer, Night Service
is activated or deactivated on all consoles.
Night Service can also be activated through system programming for special
conditions, such as a midweek holiday.
Considerations and Constraints
A Direct Inward Dialing (DID) call to any member of a Night Service group rings
at all group members' telephones.
