Figure 76. Example of a successfully received fax Explanation of DBM -dBM values shown on the fax trace report are hexadecimal numbers. Convert the value to a base-10 number and then divide by 5 to check signal strength. Using the example above, where DBM=34: 34 (hex) = 52 (decimal) and 52/5 = 10.4 Assuming a negative value, -10.4 falls into the range of -10 to -43 (with -43 being a weak signal). -10.4 is, therefore, a strong signal. 190 Chapter 6 - Troubleshooting EN
