Euro ISDN connection
Your new telephone set Eurit 40 is designed for connection to the Euro ISDN. This is a digital net-
work that is standardized throughout Europe. It offers a comprehensive range of services that are
either included in your subscription or are available as supplementary services.
There are different types of Euro ISDN subscriber connections that vary in their scope of functions.
Eurit 40 supports all functions available through Euro ISDN. It may happen, however, that you can-
not use all of these functions because they are not included in the subscription for your particular
subscriber connection. Please refer to the documentation of your network operator for a list of
available services.
Functions of Euro ISDN
Euro ISDN offers among others, the functions listed below. Please note that certain Euro ISDN func-
tions can be used only if your communications partner also has an ISDN connection to which a cor-
responding telephone set is attached (for example, the facility to transmit ”Mails”).
Multiple subscriber numbers (MSN)
Depending on the connection type your network operator may allocate several (multiple) telephone
numbers to your connection which you can assign as desired. For example, you can assign a diffe-
rent telephone number to each telephone set on the ISDN connection, or you can assign several
telephone numbers to the same telephone set.
2 exchange lines
With your ISDN connection you can establish two mutually independent external calls. This is feasi-
ble because each ISDN connection features two exchange lines that can be used independently of
each other.
