Business Features Package
Data Security
Single line telephones used with modems and fax machines can be programmed so that they
will not receive any system-generated tones that would disrupt data transmissions. In addi-
tion, these devices receive C.O. ringing pattern instead of internal ring pattern. Devices con-
nected to an SLI card receive a disconnect signal upon termination.
Database Printout
A copy of the customer database can be obtained using PCMMC (the PC program for con-
figuring the telephone system). This information can be directed to a printer or the PC screen
and may be done either on site or remotely. A complete database or specific data blocks may
be printed.
DECT Service
The system provides DECT cordless communications in a single office or throughout a large
commercial or industrial complex. To implement this service, you need a 3BSI card, DECT
Base Station(s) and DECT handsets. Users of this service meet improved overall efficiency,
since they can be reached or make calls while away from their desks.
Direct in Lines
Outside lines may be programmed to bypass the operator(s) and ring directly at any station
or group of stations.
Direct Dialling In (DDI)
Direct Dialling In (DDI) refers to digit-steered inbound call handling. This service is provided
over ISDN PRI and BRI circuits.
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 then place internal calls or, if permitted, calls using C.O. lines. The caller
must have a tone dial phone and know their DISA security code. DISA lines can be used as
both-way lines or incoming only and may be active/inactive according to the ring plan table.
The C.O. lines used for DISA must have disconnect supervision. The requirement to put in a
DISA security code can be disabled if desired.
Direct Trunk Selection
Each station can be allowed access to or denied access from a trunk or trunk group by ac-
cess code when LCR is activated. When restricted, the station user must use a trunk key or a
route key.
Directory Names
Each station, station group and C.O. line may be assigned a directory name (maximum 11
characters). In addition, each personal speed dial number, system speed dial number and
entry in the DDI translation table may be assigned a name (maximum 11 characters). These
names are displayed during calls with these ports and in the case of station and speed dial
names, can be used to originate calls. See the Dial by Name
feature in Display Features.
