ISDN
and DSL installations allow fast
transfer of large amounts of data.
The drawback is that surges can also
rapidly reach the terminal device
and damage computer equipment. The
danger can be overcome by balanced
use of basic and precision
protection devices. Basic surge
protectors where the data lines
enter the building divert all
harmful partial lightning currents.
Precision surge protectors filter
out capacitively and inductively
coupled-in voltages directly at the
terminal device.
