Call Toggling
You can switch back and forth between different tele-
phone conversations by using the R key. The inactive
telephone conversation is maintained in the interim, and
the other party cannot listen in. This additional service
must be enabled for your telephone line (see Call Wait-
ing, see Flash Key).
Call Waiting
If another caller places a call to you while you are having
a telephone conversation, you will hear a tone. If addi-
tional services are enabled for your telephone line, you
can toggle back and forth between different telephone
calls (see Flash Key; see Call Toggling).
Call-by-Call
Selection of the telephone service provider for each tel-
ephone 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 different service provider for each tele-
phone call without entering into a firm contract rela-
tionship.
Caller List
The numbers of the last callers are stored in the caller
list. This function requires that the caller identification
function be enabled for your telephone line and that the
caller not suppress the transmission of his or her tele-
phone number (see Calling Line Identification).
Calling Line Identification (CLIP)
There are two types of Calling Line Identification Pres-
entation (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 company must offer both services and must
enable them for your telephone 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
Before the dialling process begins, you can freely com-
bine 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 prefix of an inexpensive telephone service-pro-
vider (see Call-by-Call) as a telephone book entry,
select this entry and manually enter the desired tele-
phone number or select another number from the tel-
ephone book, the redial list or the caller list.

Dialling Pause
Long-distance numbers or telephone numbers with
sub-addresses/extensions sometimes require the inser-
tion of a dialling pause to prevent the dialling from
occurring too quickly and resulting in a loss of the con-
nection. The second part of the number is dialled only
after a short pause.
Digital Subscriber Line (DSL)
Data connection for private households or companies
with high transmission speeds (broadband connection)
usually for connection to the Internet. Fixed network
telephone lines can be used for the DSL connection.
Due to the frequency range used, Internet use via DSL
can be used simultaneously with the telephone line. For
private households, there are usually connections with
different transmission speeds: Asymmetric Digital Sub-
scriber Line (ADSL). A high download rate alongside a
far lower upload speed.
Direct-Dial Number
Number used to directly dial a specific extension of a
private 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 recep-
tion, taking over the line, see Additional Devices). To
use this function, additional telephones must be set to
tone dialling (DTMF tones).
