CHAPTER 7 Protection Against Lightning
7.2
Protection of Signal Lines
(1) External modem is in use
When modems are installed, damage to internal circuitry components in the modems
could result from indirect strike surges. Hence, it is recommended to install the
appropriate surge absorber.
Some modems are equipped with surge absorber within them. If modems are
installed, and the modem does not have surge absorber, installation of an external
surge absorber should be considered.
