DSL-310 ADSL Modem User’s Guide
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.
