Additional Devices
You can connect additional devices to your device, such as answering machines, telephones,
charge meters and computer 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 device, they are connect-
ed 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 telephone call. It is possible to place tel-
ephone calls through different private service providers. By placing prefixes in front of the ac-
tual telephone number, one can choose a different service provider for each telephone call
without entering 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 function be enabled for your PTT line and that the caller not suppress the trans-
mission 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 tele-
phone company must offer both services and must enable them for your PTT line. The trans-
mission of your telephone number can be turned on and off temporarily or it can be turned
off permanently (Calling Line Identification Restriction, CLIR).
