6. TROUBLESHOOTING

7.1 General Approach

When troubleshooting problems, a rational plan can save you many

hours of frustration. The following is a brief outline of standard

troubleshooting procedures.

1. Gather the facts to determine the exact nature of the problem.

2. Draw a picture of the system showing the equipment at both

the host and remote ends and the phone lines or in-house

wiring. Use this as a reference to note your observations, test

steps and test results. A picture keeps you focused and often

saves duplicate effort.

3. Record the front panel indications before changing anything.

This is an important part of fact gathering

4. If you change anything, change only one thing at a time.

5. Use the built-in test functions, especially the loopback tests.

Record your results.
