Lightning induced voltage spikes may be seen on aerial spans including 
the twisted pair, cable or electrical mains.

I have replaced modems and DSL modems due to faults created by lightning.

The mains can also suffer spikes that have other sources than lightning, 
e.g. faults in the distribution system itself.
And these spikes like will not appear on the twisted pair or cable.
