General Troubleshooting Procedures

Note
Ensure that the 1-2 and 3-4 resistances are within 10% of each other by multiplying the lower
resistance by 1.1. If the other resistance is greater than this, the test has failed.
In
Figure 55
, we show some simple steps to diagnose any part of the data cable and surge suppressors
that may be faulty. The first stage is done at the site and the second stage would require a tower climb.
Note
The cable numbering (for example, cable 5) and color (for example, Black) in
Figure 55
are
used with reference to the
Figure 51
An example of the BTS cabling
diagram (for better
understanding).
