3-7
Conference
The system allows five simultaneous conferences.
y Add-On (5 PARTIES)
Any combination of up to five parties (stations or outside lines) can be joined together in an
add-on conference. Parties may be eliminated or added after a conference has been
established.
y Unsupervised
A station user may set up a conference with two or more outside lines and then exit the
conference leaving the outside lines connected in an unsupervised (trunk to trunk)
conference.
Data Security
Single line extensions used with modems and facsimile machines can be programmed so
that they will not receive any system-generated tones that would disrupt data
transmissions. In addition, these devices will receive DCS-408 C.O. ringing pattern instead
of intercom ring pattern. Devices connected to an SLI port will receive a disconnect signal
upon termination.
Direct In Lines
Outside lines may be programmed to bypass the operator(s) and ring directly at any station
or group of stations.
Direct Inward System Access (DISA)
Users can call in on specific DISA lines at any time, input a security code and receive
system dial tone. Users can now place internal calls or, if permitted, calls using C.O. lines.
The caller must have a tone dial phone and must know his/her DISA security code. DISA
lines can be used as both-way lines or incoming only and may be active in day mode, night
mode or both. The C.O. lines used for DISA must have disconnected supervision.
Direct Trunk Selection
Each station can be allowed access to or denied access from a trunk or trunk group by
access code.
