Additional Devices
You can connect additional devices to your device, such as
answering machines, telephones, charge meters and com-
EN
puter modems; these can be connected either in series or in
parallel. Parallel connection means that the devices are
connected to another telephone socket of the same line. If
you connect the devices to the external socket of your de-
vice, they are connected in series. The fax switch of your
device can control and regulate only devices connected in
series.

Call-by-Call
Selection of the telephone service provider for each tele-
phone call. It is possible to place telephone calls through
different private service providers. By placing prefixes in
front of the actual telephone number, one can choose a dif-
ferent service provider for each telephone call without en-
tering into a firm contract relationship.
Caller List
The numbers of the last callers are stored in the caller list.
This function requires that the caller identification func-
tion be enabled for your PTT line and that the caller not
suppress the transmission of his or her telephone number
(see Calling Line Identification).
Calling Line Identification (CLIP)
There are two types of Calling Line Identification Presen-
tation (CLIP). If someone calls you, your device will show
the caller's telephone number on the display. If another
caller places a call to you while you are having a telephone
conversation, you will hear a tone. Your telephone compa-
ny must offer both services and must enable them for your
PTT line. The transmission of your telephone number can
be turned on and off temporarily or it can be turned off
permanently (Calling Line Identification Restriction,
CLIR).

Chain Dialling
see Combining Numbers
Chain Dialling
Before the dialling process begins, you can freely combine
and edit telephone book entries, manually entered digits,
numbers from the redial list or numbers from the caller list.
For example, if you have saved the telephone number pre-
fix of an inexpensive telephone service-provider (see Call-
by-Call) as a telephone book entry, select this entry and
manually enter the desired telephone number or select an-
other number from the telephone book, the redial list or
the caller list.

Dialling Pause
Long-distance numbers or telephone numbers with sub-
addresses/extensions sometimes require the insertion of a
dialling pause to prevent the dialling from occurring too
quickly and resulting in a loss of the connection. The sec-
ond part of the number is dialled only after a short pause.
Direct-Dial Number
Number used to directly dial a specific extension of a pri-
vate branch exchange.

Easylink
The Easylink function offers you additional options for
managing external devices that are connected to the same
telephone line as your device (starting fax reception, taking
over the line, see Additional Devices). To use this function,
additional telephones must be set to tone dialling (DTMF
tones).
ECM
Error Correction Mode
Encoding
The data of your fax transmission are encoded and com-
pressed for the transmission. The minimum standard is
MH (Modified Huffmann). Better encoding methods are
MR (Modified Read) or MMR (Modified Modified
Read).
Energy Saving Mode
The device is normally in the energy save mode. Whenever
you receive a fax or if you would like to print or make a
copy, your device will automatically switch back into oper-
ating mode (see Warm-Up Phase).
Error Correction Mode (ECM)
The ECM method reduces transmission errors that result,
for example, from bad telephone lines, thereby reducing
the duration of transmissions. Both of the connected fax
machines must support ECM.
