3.1.1 Setting up your Technicolor Gateway as DSL Gateway
Introduction
This section helps you to connect the Technicolor Gateway to your service provider’s network.
Signal arriving at your home
The Line signal that arrives at your home consists the following components:
A Phone signal carrying the traffic for telephony.
A DSL signal carrying the Internet traffic.
DSL Gateways have a built-in solution to remove the Phone component. No additional devices are needed, you can
connect them directly to the Line.
Telephones do not have this capability, so here you have to use a filter or splitter to remove the DSL signal.
How does a filter/splitter look like
A splitter/filter is a box that typically has the following connectors:
A Line input
This connector must be connected to the input signal that needs to be filtered.
A Phone/PSTN output
This connector offers filtered output signal. It only contains the Vo i c e component and can only be used for connecting
phones.
A Modem/DSL output (optional)
This connector offers unfiltered output. It contains both the Phone and DSL signal and can be used to connect your
Te c h n i c o l o r G a t e w a y .
Connecting the cables
The procedure to be followed depends on the fact if this filter has been integrated into your Technicolor Gateway or not.
Check the label of your Technicolor Gateway. If the product name contains:
“wIF” (for example Technicolor TG672 wIF) then your Technicolor Gateway has an integrated filter. No external filters
are needed. Follow the steps described in “Scenario 2: A Technicolor Gateway without integrated filter” on page 26.
No “wiF” (for example Technicolor TG672) then your Technicolor Gateway does not have an integrated filter. Follow the
steps described in “Scenario 2: A Technicolor Gateway without integrated filter” on page 26.
Scenario 1: A Technicolor Gateway with integrated filter
Proceed as follows:
1 Take the DSL cable. This is the gray cable that is included in your box.
This Phone signal is only used for communication over the traditional telephone network (PSTN). Voice over IP
communication will be carried by the DSL signal.
