1.1.1 DSL Requirements
Applicability
This section is only applicable if you are using your Thomson Gateway as DSL gateway. For more
information, see “User-specific requirements” on page 4.
DSL Service
The DSL service must be activated on your telephone line by your service provider.
Decoupling the voice and DSL signal
As soon as the DSL service is activated two kinds of signals will be available on your telephone line:
 Voice signals
 DSL signals
To ensure the sound quality of your phone calls, the DSL signal must be omitted from the telephone line
before it reaches your phone, otherwise you might hear a noise in the background when using your phone.
Filters and splitters
To split the DSL signal from the telephone line, you can use one of the following solutions:
 A splitter that splits the telephone signal into a DSL and Voice signal.
 A filter between your telephone outlet and your phone. This filter removes the DSL signal and passes the
Voice signal.
This filter may also be integrated in your Thomson Gateway.
