Line Features
Access Denied, Line Access Restriction
The system programmer can deny access to particular lines at certain stations in the
system. A station user cannot select a denied line for use. This feature is programmable
on a per line/per station basis in station class of service programming.
Line Answer From Any Station (Night Mode)
When the attendant programs the system for nighttime operation using the night transfer
of ringing feature, the line answer from any station feature is made active. With this
feature, a user can dial an access code over the intercom line to allow him to answer any
ringing outside line. The line need not be ringing at the user’s station for this feature to
be used.
Idle Line Preference
When a station is programmed for idle line preference, it will automatically be connected
to the first assigned idle line. The system can be programmed on a per station basis to
enable idle line preference. When idle line preference is enabled, taking the handset
off-hook will automatically connect the station to any assigned line that is idle and has
been arranged for this feature. The line button will not have to be pressed. If this feature
is used in conjunction with prime line automatic, the user will be given prime line first
when going off-hook. An idle line will be given if the prime line is in use. The station
class of service programming enables this feature on a per station/per line basis.
Line Groups
Outside lines can be grouped together in up to four different groups. Users can program
an autodial button to select a line group or manually enter a dialing code for access to a
line. Grouping can reserve certain lines for certain clusters of stations as in a
tenant-service arrangement. The assignment of line groups frees station buttons normally
used for line selection thus making these buttons available for use with a feature such as
personal DSS/BLF with station-to-station messaging. Lines are placed in line groups
with the line class of service programming.
Line Preselection
A line can be manually selected before lifting the handset (for handsfree dialing) or after
the handset is lifted.
