Direct Line Access By Station

Through program assignment, the system gives certain stations direct access to lines. The programmer
must map line buttons for use at these stations. The users then press the line buttons to select lines for use.

Direct Line Group Selection

This feature allows the programmer to put lines into line groups. A line group appears to the station user
as a single button. The system supports a maximum of 16 line groups with a line group containing any
number of lines; however, all lines in a group must be the same type. A multiline telephone can have a
line group button for each line group. A single-line proprietary telephone is either dedicated to a specific
line group, or it's user may dial a code to access a line group.
When a user presses an idle line group button or dials a line group access code, the system scans the lines
in that group and picks the first available line in a reverse hunt group. The indicator associated with the
line group button on multiline telephones is idle if at least one line in the group is idle.
Disconnect Supervision
When the programmer enables this feature for a line, the system detects any break in loop current anytime
during a call and disconnects the line. Also refer to the discussion titled, Abandoned Hold Release.

Discriminating Ringing

The system provides two types of ringing to give an audible distinction between internal and external
calls. Internal calls sound two quick bursts every four seconds and external calls sound one long burst
every four seconds, except when synchronized ringing is enabled. When synchronized ringing is enabled,
the central office ringing pattern is tracked on external calls. Incoming calls transferred by an attendant
always ring as an external call.

Do Not Disturb (DND)

Users can set any multiline telephone to a do not disturb mode (DND) using the designated programmable
button. The associated indicator turns on as an indication of active DND Plus an appropriate message
appears in the display of LCD speakerphones. Under the DND condition, an outside call forwards to
another station or to the attendant according to the call forwarding feature. An intercom number call will
not ring a DND station and the system sends a fast busy signal to the caller to distinguish from a standard
busy line. No paging announcements are received on the DND station. Even though a station is in the
DND mode, the user can make out-going calls and access other features.

You can enable or disable this feature on an industry-standard telephone by dialing the feature code
