Tables 1 to 6 summarize the surge needs defined by Bellcore regarding both lightning and AC power fault.
In case of first level test, the equipment under test shall be operating after the surge. For the second level
tests, the equipment under test may be damaged, but no fire or electrical safety hazard may occur.

Lightning phenomena are the most common surge causes. The purpose of this test is to check the
behavior of the CLP270M against these lightning strikes.
