6.1.2 Connection to the Traditional Telephone Network
Combining VoIP with the traditional telephone network
Some service providers use the traditional telephone network (PSTN) as a backup solution for your VoIP
connection. This way, you can still make calls over the traditional network if the VoIP service is down (for
example, your Thomson Gateway is powered off).
Applicability
If your Thomson Gateway:
 Has an integrated filter, no additional connections are needed.
The DSL port must be directly connected to your telephone outlet. Do not put any filter or splitter
between them!
 Does not have an integrated filter, check if your Thomson Gateway has a PSTN port on the back panel (for
more information, see “ PSTN Port (optional)” on page 9). If your Thomson Gateway has:
 A PSTN port:
Connect the PSTN port to the Phone output of your filter or splitter.
 No PSTN port, no connections are needed.
This is a VoIP-only variant. All calls passing through the Thomson Gateway will be done via VoIP.
Be aware that, if you are not connected to the traditional telephone network, emergency calls will
not be possible when your Internet connection is down or your Thomson Gateway is powered off.
How do I know if my Thomson Gateway has an integrated filter?
Check if the product name printed on the label of your Thomson Gateway ends with “wIF”
(with Integrated Filter). If this suffix is not present, then your Thomson Gateway does not have
an integrated filter.
