Introduction
The telephone
Connection type
Your telephone is designed for use with an ISDN basic access (DSS1 protocol, Euro-ISDN) and
can be operated at the subscriber connection (NT+2ab), the ISDN bus (S-Bus) or in conjunction
with a PBX. The telephone is powered via the NT+2ab power supply or the PBX. In the event of
a power failure, a backup supply powers the telephone via the local exchange (for PBX opera-
tion, refer to the PBX documentation).
User concept
Every user can define his or her own settings. Call charges are recorded separately for every user
(for details on the user concept, see »User concept« under the Chapter »Telephoning«).
Advanced features
You can store up to 100 numbers in the dynamically managed phonebook.
Six speed dial buttons, each for two numbers, allow you to dial numbers simply by pressing a
button.
A wide range of user-friendly features make your new telephone easy to operate and enhance
calling comfort. For a summary of these features, see the contents list.
