Page 4: How It Works
HOW IT WORKS The TWT-1 Analyzer is easy to use in quick testing of the telephone lines. It will indicate by the color of the LED if the wiring is correct, reversed or if it is not working at all. Figure 5 It has four bi-colored LEDs that will light green or red. - Page 5 WIRING CONFIGURATIONS FOR RJ-45 JACKS The RJ-45 indicates an 8-wire plug or jack. There are many standards which dictate which wire pairs connect to which pins on a plug or jack. Some of these standards are listed below. EIA/TIA-568A EIA/TIA 568B or AT&T 258A Token Ring Figure 9...

Page 9: Testing And Troubleshooting
TESTING AND TROUBLESHOOTING 1. One of the most frequently occurring problems is poor solder connections. a) Tug slightly on all parts to make sure that they are indeed soldered. b) All solder connections should be shiny. Resolder any that are not. c) Solder should flow into a smooth puddle rather than a round ball. -

If wall plates with RJ-11 are not available, then you should use the telephone line simulator Model TT-250.
- Page 12 USING THE TELEPHONE LINE ANALYZER ON RJ-45 JACKS When testing an RJ-45 jack and there are two lines coming into the jack, two LEDs will be lit. If you have four lines coming into the jack, four LEDs will be lit. If wall plates with RJ-45 jacks are not available, then you should use the telephone line simulator Model TT-250.
