Night Service Feature

Description

Each Night Service group is associated with either an individual QCC (in Hybrid/PBX mode) or an individual DLC through system programming.

A Night Service group can include the following types of members:

• Any type of extension
  
  
• One Calling Group for each Night Service group
  
  
• Calling Group with one non-local member
  
  
• Outside lines must be assigned to Night Service groups in order for calls received on these lines to receive Night Service treatment. The System Manager can assign the following types of outside lines to Night Service groups:
  
  
• Loop-start lines
  
  
• Ground-start lines
  
  
• NI-BRI B-channels
  
  
• PRI B-channels that are routed by line appearance
  
  
• Automatic incoming tie trunks

• DID (Direct Inward Dial) trunks
  
  
• Dial-in tie trunks
  
  
• PRI B-channels that are routed by dial plan
  
  
• Line/trunk jacks programmed for Alarm, Music-On-Hold, or Paging
  
  
• Unequipped line/trunk jacks
  
  
• Night Service group members and operators must all be local system users. Private trunks should not be assigned to Night Service groups.

During Night Service operation, calls received on lines assigned to a Night Service group ring at the Night Service destination for the group (an extension or Calling Group). A line need not be assigned to an operator position in order to receive Night Service coverage to a Calling Group. Lines that are not assigned to a Night Service group, whether or not they appear at operator consoles, do not receive Night Service treatment.

SECURITY ALERT:

Avoid programming a Remote Access line as a destination for Night Service for any published telephone number. Professional toll-fraud criminals scan telephone directories for published local and 800 telephone numbers. Using these numbers, they attempt to gain access to the system, then may use such features as Remote Access to reach outside facilities from within the system. For additional information about toll fraud, see Appendix A, "Customer Support Information."

An extension in a Night Service group is considered unavailable, and a Night Service call does not ring at that extension when any of the following situations occur:

• A telephone is in extension or system programming mode.
  
  
• A user with a 4400-Series or 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.
  
  

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. Each extension can be assigned to more than one group.
