MERLIN LEGEND Communications System Release 5.0
Feature Reference 555-650-110
Features
Night Service
One calling group (Release 2.0 and later) for each Night Service group.
In Release 4.1 and later systems, 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
The following types of outside lines cannot be assigned to Night Service
groups:
— 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
In Release 4.0 and prior systems, when an operator associated with a Night
Service group activates Night Service or when the Time Set option turns on Night
Service operation automatically, any calls received on lines/trunks programmed to
ring at individual operator consoles ring immediately at all available extensions
assigned to the group.
During Night Service operation in Release 4.1 and later systems, 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.
!
SECURITYlALERT:
Avoid programming a remote access line as a destination for Night Service
on 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 Service Information."
