You can arrange an Internet connection through a telephone line with ADSL service by using Keenetic DSL (KN-2010) and Keenetic Duo (KN-2110) routers. They are equipped with a built-in modem ADSL2+/VDSL2, which allows you to connect to the Internet using DSL technologies without any external modems or routers. The ADSL connection can be used as primary or as backup connection, which can be activated automatically in case of problems on the main Internet access channel.
TIP: Note: Keenetic DSL, Duo support ADSL2+ Annex M mode. This mode is a part of the ADSL2+ standard and allows to increase the upstream speed (data transfer rate to the provider). This ADSL2+ Annex M mode is activated automatically, provided that it is activated on the ISP side.
Connect the telephone line to the RJ-11 connector on the router. Be sure to use micro-filters or DSL splitters to connect all telephones to your telephone line, this will isolate the modem from the interference phone creates on the line, while protecting the phone from high-frequency modem signals. Microfilter and splitter do not affect the operation of the phone, and if properly connected, the phone should work the same way as before they are installed.
Go to the 'DSL Connection' page. In the 'DSL technology' field, select 'ADSL'.
On this page, specify the settings for your Internet connection.
NOTE: Important! The VPI, VCI values, username and password for Internet access are usually specified in the contract concluded between the subscriber and the ISP.
In the 'PVC settings for the Internet' section, it is necessary to set the values 'VPI/VCI' and 'Encapsulation'. In our example, the VPI/VCI values are 0/35 and the encapsulation is LLC.
Next, on the same page, in the 'IP settings' field, select 'No IP address', as it is not required to assign an IP address on this virtual channel.
PPPoE authentication will be used to connect to the Internet. In the 'ISP authentication' section, specify 'PPPoE' in the 'Type (protocol)' field, and in the 'Username' and 'Password' fields type in the values provided by your ISP for connecting to the Internet.
Click 'Show advanced PPPoE settings' to display the fields with additional parameters.
For more information on configuring PPPoE, see the article 'Internet connection via PPPoE'.
