2.1.1 Setting up your TG789vac v2 as DSL gateway
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.
What 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
TG789vac v2.
Connecting the cables
The procedure to be followed depends on the fact if this filter has been integrated into your TG789vac v2 or not.
Check the label of your TG789vac v2. If the product name contains:
• “wIF” (for example TG789vac v2 wIF) then your TG789vac v2 has an integrated filter. No external filters are needed.
Follow the steps described in “Scenario 2: A TG789vac v2 without integrated filter” on page 17.
• No “wiF” (for example TG789vac v2) then your TG789vac v2 does not have an integrated filter. Follow the steps
described in “Scenario 2: A TG789vac v2 without integrated filter” on page 17.
Scenario 1: A TG789vac v2 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.
