Although you can use your 2-line
telephone with a single phone line, you
must have two lines (separate phone
numbers) to use a two-line system. The
following diagrams show two possible
systems:
Two Lines on a Single Modular Jack
One type of two-line phone system uses
a single RJ14 modular jack which
contains both phone lines. Connect the
phone cord to the LINE 1+2 jack.
You must use a 4-conductor telephone
line cord like the gray one packed with
your unit.
