For 2-line telephone wiring
If the telephone wiring coming into your
building consists of 2-line wires (each cable
carries two telephone lines), use the RJ-14
cables supplied with the Controller to plug
the primary incoming line (Lines 1 and 2) into
the Line 1 Connector.
If you have a second incoming 2-line cable
(Lines 3 and 4), plug it into the Line 3
Connector. Be sure in this instance to leave
the Line 2 and Line 4 Connectors empty -
see the following illustration.
