How it Connects

The Digital Line Tester is equipped on one end with a short cord and RJ-11 plug that plugs into the telephone wall jack for the line to be tested and at the other end a RJ-11 jack for your modem cord. If no correction is indicated by the testing, the modem cord is plugged into the jack and the Digital Tester is used as an on-line connector between the wall jack and your modem. Complete, easily-understood instructions are enclosed.
