Private Branch Exchange
Private branch exchanges are common in larger compa-
nies. Even private ISDN systems can be branch exchang-
es. 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 Outside Line Ac-
cess Code).
PSTN
Public Switched Telephone Network
Pulse Dialling
A dialling process that is used in older telephone net-
works. You hear a clicking for each number dialled (see
Tone Dialling).
RJ-11
Registered Jack 11 (also called Western plug, standard-
ised telephone plug)
Scanning
The reading of a document into the fax memory or into
the computer in order to send it, copy it or edit it.
Sender Identification (= Header)
The telephone number and name of the sender as well
as the date and time of the fax transmission appear in
the upper margin of each received fax.
Sending to Multiple Recipients (=
Broadcasting)
With this function, you can send a fax message to mul-
tiple recipients.
Telephone number suppression (CLIR)
If you call a subscriber, your number appears on the dis-
play of the person whom you are calling. You can switch
off this function and suppress your number (Caller Line
identification Restriction, CLIR).
Time Stamp
The exact date and time of receipt appear in the page
header of each received fax. A memory buffer guaran-
tees that exact data are issued even after a power loss.
In this way, you can verify exactly when a fax has
reached you.
Tone Dialling (= Dual Tone Multi-
Frequency)
In many countries, tone dialling has replaced pulse dial-
ling, in which each number was sent as a corresponding
number of pulses. With tone dialling, a specific tone is
assigned to each key (referred to as DTMF tones).
Toner Level Memory
Your device registers the extent of toner used for every
print-out and calculates the toner level of the toner car-
tridge on that basis. The toner level is stored in each
toner cartridge. You can use different toner cartridges
as well as display the respective toner level of the toner
cartridge.
Transfer Speed
CCITT/ITU has published international standards for
the transmission of data over telephone lines. All short
names begin with V, so these are also referred to as V
standards. The most important transmission speeds for
fax transmissions are: V.17—7.200 to 14.400 bps,
V.21—max. 300 bps, V.22—max. 1.200 bps, V.22 bis—
max. 2.400 bps, V.27 ter—max. 4.800 bps, V.29—max.
9.600 bps, V.32 bis—max. 14.400 bps, V.34—max.
33.600 bps
TWAIN
(Tool Without an Interesting Name) With the TWAIN
scanner driver you can access the device and scan doc-
uments from any application which supports this stand-
ard.
USB
Universal Serial Bus (computer port)
UTC
Coordinated Universal Time (UTC) Coordinated Uni-
versal Time is the current standardised universal time
used. Starting from Greenwich in London (Zero Merid-
ian), the world is split into time zones. These time zones
are indicated with a deviance from UTC (in hours) for
instance UTC+1 for Central European Time (CET)
Warm-Up Phase
Normally, the device is in the energy saving mode (see
Energy Saving Mode). In the warm-up phase, the device
heats up the printing unit until it has reached the neces-
sary operating temperature, after which the copy or fax
can be printed out.
