Line Splitter
If you are instructed to use a “line splitter”, you must install the device between the Modem and the phone jack.
Use standard telephone cable with standard RJ-11 connectors. The splitter has three RJ-11 ports used to connect
to the wall jack, the Modem and if desired, a telephone or telephone device. The connection ports are typically
labeled as follows:
Line - This port connects to the wall jack.
ADSL – This port connects to the Modem.
Phone – This port connects to a telephone or other telephone device.
The diagram below illustrates the proper use of the splitter.
