Step 1:
Install the ISDN ADSL Splitter

The ADSL technology uses the existing telephone line for the broadband entrance. With the
ISDN installation a ISDN ADSL-Splitter must be installed to separate the frequency ranges of
ADSL and ISDN and to prevent disturbances at ISDN phones or fax machines. Use for installati-
on the provided ISDN ADSL-Splitter.

Important note:

- With an ISDN installation only one ISDN ADSL-Splitter is needed for the entire ISDN

installation.

For Phones or fax machines with ADSL and ISDN there is no Line-Filter needed.

Please contact your support-technician if your ISDN-NT (ISDN Networkterminator) is
not equipped with a plugged incoming line.
