General Description
DCS-816
March 1999
4 - 7
First Party Call Control. A DCS-816 Computer Telephony Module (CTM) is
required to connect any keyset to a PC running Windows 3.1 or Windows
95. The number of CTMs that can be installed on a system is only limited
to the number of keyphones. The features and functionality of the DCS-
816 keyset are not changed.
Conference
The system allows five simultaneous conferences.
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.
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-
816 C.O. ringing pattern instead of intercom ring pattern. Devices connected to
an SLI port will receive a disconnect signal upon termination.
Direct Dialling Inward (DDI)
The system can use local telephone-company–provided DDI service via an
ISDN. When programmed, anyone dialling a user's personal number will ring
directly to that user's office. DDI calls to a busy station have the option to return
busy signal to the C.O. or return ringback to the C.O. When ringback is
selected, the called station receives off–hook ring. Multiple DDI numbers can
ring the same extension or station group, and display keysets show a DDI
directory name when ringing if a name has been programmed. DDI calls that are
directed to ring a voice mail machine can be identified by a special digit.
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 disconnect supervision.
Direct Trunk Selection
Each station can be allowed access to or denied access from a trunk or trunk
group by access code.
