Ch. 1 3550-US-5.0 SETUP & PREPARATION BEFORE USE FOR YOUR INFORMATION Roll Over Phone Lines A roll over phone system is a group of two or more separate telephone lines that pass incoming calls to each other if they are busy. The calls are usually passed down or "rolled over" to the next available phone line in a preset order. Your fax machine can work in a roll over system as long as it is the last number in the sequence so the call can not roll away. Do not put the fax machine on any of the other numbers. When the other lines are busy and a second fax call is received, the fax call is transferred to a line that does not have a fax machine. Two Line Phone System 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 fax machine must be plugged into an RJ11 jack. RJ11 and RJ14 jacks may be equal in size and appearance and both may contain 4 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 lines for your fax machine. Converting Telephone Wall Outlets There are three ways to convert to an RJ11 receptacle. The first two ways may require assistance from the telephone company. You can change the wall outlet 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 wall outlet. It will separate the wires into two separate RJ11 jacks (line 1, line 2) and a third RJ14 jack (lines 1 and 2). Plug the fax machine into L2 of the triplex adapter. RJ14 L1 L2 L1+L2 RJ11 RJ11 RJ14 Triplex Adapter 1-9
