Direct-Dial Number (also Exten-
sion):
Number used to directly dial a
specific extension of a private branch ex-
change (see Private Branch Exchange).
Dual Tone Multi-Frequency (DTMF):
see Tone Dialing
Encoding:
e data of your fax transmis-
sion are encoded and compressed for the
transmission. e minimum standard is
MH (Modified Huffmann). Better encod-
ing methods are MR (Modified Read) or
MMR (Modified Modified Read).
Energy Saving Mode:
e machine is nor-
mally in the energy save mode. Whenever
you receive a fax or if you would like to
print or make a copy, your machine will
automatically switch back into operating
mode (see Warm-Up Phase).
Error Correction Mode (ECM):
ECM method reduces transmission errors
that result, for example, from bad tele-
phone lines, thereby reducing the duration
of transmissions. Both of the connected
machines must support ECM.
Fax Groups:
Machines are classified in
terms of internationally standardized fax
groups based on their transfer type and
speed. Connections between two devices
of different groups is possible; the low-
est common transfer rate is selected. e
determination of the speed takes place
during the handshake (see Handshake).
Fax groups 1 to 3 are analog machines.
Nowadays, groups 1 and 2 are hardly to
be found any longer; machines of group
3—which have a transfer speed that ranges
from 9,600 to 33,600 bps—are currently
most standard. Group 4 machines are
digital devices that function exclusively
on ISDN systems. ey have a maximum
transfer speed of 64,000 bps.
Fax Polling:
With active fax polling, one
can retrieve a document from another
machine. For fax polling from a larger
company offering several polling services,
you can also enter sub-addresses / direct-
dial numbers. In order to do this, you
must insert a dialing pause between the
fax number and the sub-address.
Fax Signal, also CNG Tone (Calling
Signal):
e tone that a machine sends
out to announce a fax transmission. When
the CNG tone occurs, the fax switch of the
device recognizes an incoming fax call and
starts the fax reception.
Fax Switch:
e fax switch checks in-
coming telephone calls and controls
the ringing behaviour of the machine.
According to the selected mode, fax
transmissions will be received either
automatically or manually.
Flash Key (R/PAUSE Key):
flash key, you can make use of additional
telephone services if these special func-
tions are enabled for your telephone line.

Handshake:
e handshake is the initial and
final phase of a fax transmission. After es-
tablishing the connection, machines check
the group affiliation and features such as
size, compression or grey tones. After the
e fax transmission has been completed and
before the connection is terminated, the
receiving device confirms receipt of the
transmission (see Fax Groups).
Hard modem:
e hard modem is a fixed,
built-in modem. In contrast to the soft
modem, its features and functions are
fixed and thus cannot be changed (see Soft
Modem, see Modem).
Hook-Flash Function:
Journal:
e journal contains information
pertaining to the last 30 telephone calls
as well as to sent and received faxes and
Text2Fax messages. e journal can be
printed out manually or the machine can
be set to dispense automatic print-outs at
specific times (for example after 30 trans-
missions).
Memory:
If there is no paper or toner in your
machine, the machine will store incoming
fax transmissions in its memory.
Modem:
A modem converts digital
computer signals into acoustic signals
and vice versa. Analog telephone lines
transfer only acoustic signals, not digi-
tal signals (see Hard Modem, see Soft
Modem).
Outside Line Access Code:
line access code is the number or letter that
must be dialed before the actual telephone
number on a telephone of a private branch
exchange in order to establish a connec-

Private branch
exchanges are common in larger companies.
Even private ISDN systems can be branch
exchanges. To establish a connection to the
public telephone network from a private
branch exchange, one must dial a number
or press a key before the actual telephone
number; in most cases this is zero (see Out-
side Line Access Code).

For sending and receiving faxes, the reso-

resolutions are Fast, Quality and Photo.
