Single Phone Installation
A single-line cordless or wired phone can be plugged directly into the phone jack in the back of this equipment. In this type of installation no connection is made to existing telephone wiring. (These instructions are included in the box with this equipment.) You can also use a 2-line phone and connect your active Line-1 phone line from the wall to the "L2" port and this equipment to the "L1/2" port on the 2-line phone. You can then answer or place calls on either your home line or this interconnect equipment from one 2-line phone. This is shown in the diagram below.
