Phone services and external devices Two-line phone system 7 A two-line phone system is nothing more than two separate phone numbers on the same wall outlet. The two phone numbers can be on separate jacks (RJ11) or combined into one jack (RJ14). Your machine must be plugged into an RJ11 jack. RJ11 and RJ14 jacks may be equal in size and appearance and both may contain four wires (black, red, green, yellow). To test the type of jack, plug in a two-line phone and see if it can access both lines. If it can, you must separate the line for your machine. (See Easy Receive on page 42.) Converting telephone wall outlets 7 There are three ways to convert to an RJ11 jack. The first two ways may require assistance from the telephone company. You can change the wall outlets from one RJ14 jack to two RJ11 jacks. Or, you can have an RJ11 wall outlet installed and slave or jump one of the phone numbers to it. The third way is the easiest: Buy a triplex adapter. You can plug a triplex adapter into an RJ14 outlet. It separates the wires into two separate RJ11 jacks (Line 1, Line 2) and a third RJ14 jack (Lines 1 and 2). If your machine is on Line 1, plug the machine into L1 of the triplex adapter. If your machine is on Line 2, plug it into L2 of the triple adapter. RJ14 Installing machine, external two-line TAD and two-line telephone 7 When you are installing an external two-line telephone answering device (TAD) and a two-line telephone, your machine must be isolated on one line at both the wall jack and at the TAD. The most common connection is to put the machine on Line 2, which is explained in the following steps. The back of the two-line TAD must have two telephone jacks: one labeled L1 or L1/L2, and the other labeled L2. You will need at least three telephone line cords, the one that came with your machine and two for your external twoline TAD. You will need a fourth line cord if you add a two-line telephone. Place the two-line TAD and the two-line telephone next to your machine. Plug one end of the telephone line cord for 7 your machine into the L2 jack of the triplex adapter. Plug the other end into the LINE jack on the back of the machine. Plug one end of the first telephone line cord for your TAD into the L1 jack of the triplex adapter. Plug the other end into the L1 or L1/L2 jack of the two-line TAD. Plug one end of the second telephone line cord for your TAD into the L2 jack of the twoline TAD. Plug the other end into the EXT. jack on the left side of the machine. 1 2 RJ11 RJ14 3 4 1 Triplex Adapter 2 Two Line Phone 3 External Two Line TAD 4 Machine 51
