Night Service with Outward Restriction prevents unauthorized after-hours use of
telephones. When the option is programmed, only authorized system 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 system 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, a user must enter a password
before a non-emergency outside call is made. When the correct password is
entered, the system then checks for calling restrictions assigned to each
telephone before allowing calls to outside numbers.
A Night Service emergency numbers list can be created that includes up to 10
numbers, for example, police or fire departments, 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 a
password is entered first.
One exclusion list can be created to exempt specific telephones from the
password requirement. An unlimited number of telephones can be assigned to
the list. However, normal calling restrictions (if any) assigned to the telephone
are still in effect. Unrestricted telephones on the exclusion list are not protected
against unauthorized after-hours use.
When the Night Service with Time Set option is programmed, the system
automatically activates Night Service on all system 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. However, 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.
Only system operators can activate Night Service by using a direct-line console
(DLC) or a queued call console (QCC). To activate or deactivate Night Service,
the system operator presses the programmed Night Service button. If the Night
Service with Outward Restriction option is programmed, when the system
operator presses the programmed button, the green LED flashes and the
system operator must enter the assigned password (within 60 seconds) to
activate or deactivate Night Service. When Night Service is activated, the green
LED next to the programmed button goes on. When the feature is deactivated,
the green LED goes off.
