Feature Reference
Description
Night Service provides options for after-hours telephone operation that can be
programmed in any combination of the following:
Night Service with Group Assignment
Night Service with Outward Restriction
Night Service with Time Set
NOTE:
The term after-hours is only used for convenience. Night Service can operate at
any time it is activated and is intended for use outside of normal business hours.
Only operators can activate or deactivate Night Service by using a Direct-Line
Console (DLC) or a Queued Call Console (QCC). To activate or deactivate Night
Service, an operator presses the programmed Night Service button. If the Night
Service with Outward Restriction option is programmed, the green LED flashes
when the DLC operator presses the programmed Night Service button, and the
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 Night Service button turns on. When the feature is
deactivated, the green LED turns off.
Night Service Group Assignment
Each Night Service group is associated with an individual QCC (in Hybrid/PBX
mode) or an individual DLC during system programming. Any type of telephone
or one calling group (Release 2.0 and later) can be a member of a Night Service
group.
When an operator associated with a Night Service group activates Night
Service, any calls received on trunks programmed to ring at individual consoles
ring immediately at all available extensions assigned to the group. An extension
in a Night Service group is considered unavailable and a Night Service call
does not ring at it when any of the following occurs:
A telephone is in the extension or system programming mode.
A user with an MLX display telephone is using Alarm Clock or Directory
features.
A telephone is busied-out for maintenance or system programming.
All SA or ICOM buttons are in use.
A single-line telephone user is on a call.
NOTE:
Up to eight Night Service groups can be created, one for each operator. There
is no limit to the number of extensions assigned to each group, and each
extension can be assigned to more than one group.
