A Direct Inward Dial (DID) call to any member of a Night Service group rings at all group members' telephones.
If an extension assigned to a Night Service group has the same outside line (Personal Line) as an operator console, calls to this line ring immediately at each extension, even if the Personal Line on the telephone is programmed for Delay Ring or No Ring. If the extension does not have the outside line assigned, the call rings on an SA or ICOM button.
When Night Service is deactivated by an operator or automatically by the system, extensions are reset to their programmed Ring Timing options.
When a feature code is used to activate or deactivate Night Service, and Outward Restriction is programmed, a DLC operator does not hear an error tone if an invalid password is entered. Unless a Night Service button is programmed, an operator cannot determine whether Night Service is active.
When both the Night Service with Outward Restriction and Night Service with Time Set options are programmed, the system imposes restrictions automatically.
When Night Service with Outward Restriction is used, an operator must enter a password to manually activate or deactivate Night Service.
When Night Service with Outward Restriction and/or Night Service with Time Set are programmed, Night Service is activated or deactivated for all operator consoles. If Night Service groups are also programmed, Night Service cannot be activated or deactivated separately for each group.
When Night Service with Outward Restriction is activated and a user with a restricted extension presses a dialpad button while on a call, the call is disconnected, the user hears a fast busy signal, and the line/trunk is released. When the dialpad is used, the system assumes that the user is trying to make an outside call, which is not allowed because of the Night Service restriction assigned to the extension.
Operators can override Night Service with Time Set and turn Night Service on or off manually.
Night Service with Time Set can be deactivated through system programming for special conditions such as a midweek holiday.
An answering machine connected to a 016 (T/R) module or to a port on a 016 ETR module programmed as a tip/ring port can be set up as a member of a Night Service group to automatically answer after-hours calls. External alerts, such as strobes, bells, or chimes, can be connected either to an MLX telephone by using a Multi-Function Module (MFM) that is a member of a Night Service group. The external alert sounds or lights when a Night Service call comes in to that telephone.
Changing the system time while in Night Service mode deactivates Night Service; Night Service then must be reactivated manually.
Night Service with Coverage Control controls voice messaging system coverage only and has no effect on other forms of coverage, such as Individual Coverage or other types of Group Coverage. When the option is disabled, Night Service does not affect programmed Coverage VMS Off buttons.
If a user with a programmed Coverage VMS Off button activates or deactivates Coverage by pressing the button on his or her telephone, the next transition to Night Service does not necessarily toggle the button to the opposite status. Instead, when Night Service goes on or off, the button assumes the same active or inactive state that it would have if no manual button-press had taken place. The most recent event, whether it is a manual button-press or an automatic change set by the Coverage Control option, determines the active/inactive state of the programmed Coverage VMS Off button.
