About ISDN
This cordless phone is suitable for use with Euro-ISDN. ISDN, which stands
for Integrated Services Digital Network, integrates the simultaneous transmis-
sion of speech and data. With Euro-ISDN you have access to two digital tele-
phone lines. This makes it possible, for example, to have two telephone
conversations at the same time or to have an ISDN internet connection with
your computer on one line and still be able to make and receive telephone
calls on the other line.
ISDN comes with several telephone numbers (network operator and subscrip-
tion dependent), making it possible to reserve a phone number for instance for
business calls and another number for private phone calls (see “Multiple Sub-
scriber Numbers (MSN)” on page 20 for more information). The ISDN serv-
ices described in this manual are operator and subscription dependent.
Installation
You can install the cordless phone directly to the ISDN network terminal,
which may also have other devices attached, such as an ISDN modem or a fax
machine.
Warning Make sure the local mains voltage corresponds to the voltage on the
power adaptor. Only use the power adaptor that comes with the set.
When installing the cordless phone, it is important that you closely follow
the procedure below:
1. Insert the battery in the handset.
2. Find a suitable location for the base station. To make the best use of its
operating range, put your base station in a central position. You can place
it on a table using the desk stand or mount it on the wall using the wall
