CHAPTER 5: TROUBLESHOOTING

 

 

This chapter describes procedures for troubleshooting most problems

 

 

that may be encountered while installing, configuring, and operating the

 

 

7400B Data Module.

HOW TO USE THIS

 

 

 

Use the following guidelines to isolate and correct a problem:

CHAPTER

 

1. Scan through the “Symptom” column in the chart to find the

 

 

 

 

description that best describes the problem situation you have

 

 

encountered.

 

 

2. In the “Problem” column, one or more problem descriptions is

 

 

offered. Select the one that best describes the observable

 

 

condition, or try each suggestion in turn until the trouble has been

 

 

corrected.

 

 

3. Perform the task described in the “Solution” column. In cases

 

 

where you are directed to type an AT command to correct the

 

 

problem and the 7400B Data Module is in the command mode,

 

 

simply type the command; from data mode, do the following:

 

 

a.

Type the escape sequence (+++) to enter command mode;

 

 

 

the data module will respond with OK or 0 (unless the Q1

 

 

 

option has been set to disable result codes).

 

 

b.

Type the suggested command line (if the solution suggests

 

 

 

disconnecting the call, type the command line ath [ Enter ]).

4. To return to data mode after using the escape sequence to enter command mode, type the command line ato [ Enter ].
