| DDI – Direct Dial
Inwards |
| A key ISDN feature giving you
the ability to assign individual phone numbers
(DDI Numbers) to extensions and departments,
enabling callers to dial them directly without
having to go through the operator.
|
| DECT Phones |
| DECT is the acronym given
to the new digital cordless telephony standard
available. DECT systems are far superior to
their analogue cousins in a number of respects
and users of DECT are nearly always delighted
with the improvement compared to an old analogue
cordless phone. DECT Cordless handsets can
provide wireless communications within an
office or company premises. The handsets can
be fully integrated with the company phone
system, allowing users to make, take and transfer
calls securely as they move around the premises.

| Digital Cordless
Phones |
| Digital cordless phones now
have lots of features, many the same as those we
have come to rely upon with our mobile phones.
Cordless phones can easily plugged into your
analogue or digital phone sockets or telephone
system extensions boxes.
|
| DPNSS (Digital Private
Network Signalling System) |
| If your company has two
offices or more, you may wish to run both your
voice and data communications across the same
network from one centralised location. This
offers a number of costs savings as you will
only have to pay for one backbone infrastructure
instead of two or three, one network management
and one group of technical personnel. These
capabilities can be provided by most, if not
all, PBX manufacturers without large dedicated
investments or high re-occurring expenses.
|
| DSS – Direct Station
Select |
| A button on a terminal that
can be used to directly dial a person or
extension associated with that button.
|
| DTMF – Dual Tone Multi
Frequency |
| Signaling which is the basis
for the operation of pushbutton telephone sets.
Dialed numbers are transmitted as tones rather
than electronic pulses. This is particularly
useful for access to supplementary services
(e.g. voicemail and auto attendants).
