Call Toggling

You can switch back and forth between different telephone 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 additional 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 telephone 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 telephone 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 telephone number (see Calling Line Identification).

Calling Line Identification (CLIP)

There are two types of Calling Line Identification Presentation (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 EN 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 telephone number or select another 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 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 Subscriber 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).
