1.2.2.2 ADSL/ADSL2+ connection over PSTN (DSL connector)
The Teldat C1+L router has a DSL connector to connect to an ADSL/ASDL2+ network over PSTN. This is a female
RJ11 connector with 4 wires. The central pair is used for data transmission/reception.
For connection, you can use the telephone cable with male RJ11connectors that are provided with the device.

The splitter
The Full Rate ADSL (ITU G.dmt or G.922.1) operating mode uses a higher transmission capacity that does not allow
the use of telephones directly connected to the same line; it is necessary to use a mechanism known as "splitter" ,
which separates the band frequencies for voice telephony from those used for the ADSL connection to transmit data.
This way, interferences between the telephone service and ADSL service are avoided (and vice-versa).
A typical installation with a splitter is shown in
