48 Digital Family Features
DSS Add-on unit
The Direct Station Select (DSS) Add-on unit provides
one-touch dialing of up to 120 Directory Numbers and
speed dial numbers and a visual Busy Lamp Field
(BLF) indication for up to 120 extensions. Up to four
units may be chained together and attached to any
Avanti Attendant, Avanti 3025, Avanti 3020F, Avanti
3020H, Avanti 3015DF, Avanti 3015DH, or Avanti
3015H set. Alternatively you can shift between the
four button maps on a single DSS Add-on unit. With
the DIGITAL 400 and DIGITAL 1000 systems, up
to eight button maps may be programmed with a
maximum of four assigned to each DSS Add-on unit.
The DIGITAL 1000 system supports up to 48 DSS
Add-on units, while the DIGITAL 400 and DIGITAL
KEY BX support 16 and eight DSS units, respectively.
DTMF signaling to SLT ports
The DIGITAL systems provide DTMF signaling to
SLT ports to enable operation of external equipment
such as standalone Voice-Store-and-Forward machines,
facsimile machines, etc.
Elapsed time starter
For each trunk or trunk group, you can define the delay
after dial completion before the system starts timing
the call.
Electronic Business Card*
See Electronic Business Card in Section 6, ImaGEN
Application Generator and Other Optional Features,
above.
Equal access support
You may choose a particular carrier for a call. If dialing
via Least Cost Routing (LCR), the system selects the
most economical carrier automatically. Different
restriction routines can be defined for calls on different
carriers.
Error message history file
Records of system errors, which generate system alarms
and diagnostic messages, are stored in the Error
Handling Unit (EHU) history file. This enables
maintenance technicians to see, at a glance, the source
and history of system malfunctions.
External bell interface
Incoming calls arriving in a noisy environment or at
distant extensions can be programmed to ring at external
bells. This ensures that all calls can be heard. Different
ringing patterns can be programmed for day and night
service. Up to four external bells may be configured
in the DIGITAL KEY BX system, up to eight in the
DIGTAL 400 system, and up to 48 in the DIGITAL
1000 system.
Flash type
You can define the default flash type for the system as
either flash or signal. For individual calls you can
override the default flash type. The preferred default
depends on how your DIGITAL system is configured.
Flexible Numbering Plan (FNP)
The code assigned to each extension, trunk, trunk
group, or feature is flexible. The customer can select
the code (up to four digits long) to be dialed when
accessing each facility in the system.
Half Private Trunk Groups (HPTG)
Half private trunks are regular private trunks that, for
outgoing calls only, are grouped under a single Flexible
Numbering Plan (FNP). In other words, they can be
called directly from the outside but share one trunk
group access code for placing outside calls. This allows
stations with many buttons to receive the trunk
appearance and users of more simple stations to select
outgoing trunks by using a single code.
Hearing aid compatible
All of the telephones available with the DIGITAL
family of systems are hearing aid compatible.
