[comp.dcom.modems] Modem encountering power

wtm@neoucom.UUCP (Bill Mayhew) (08/31/89)

Back in the days when 1200 baud modems cost about $450, my modem at
home was one of a nubmer of things that fell prey to a tactical
lightning strike.

The lightning came down the chimney, hopping out of the mortar
above the fireplace and also the water heater flue in the basement.
Many things electronic as well as inert objects were either damaged
or vaporized.  The modem was apparently one of the things that took
an indirect dose via current that was induced into the phone lines
inside the house.

All in all there were several thousands of dollars of damage, and a
new modem was among the things the insurance company bought me.

To the credit of the former Ma Bell (pre-break-up), her model 500
desk phone survived the nuking, as did the 50+ year old protection
block at the wire entrance.  A cheap import phone, an answering
machine, and the modem were blown away.  A postmortem of the modem
revealed that the gas surge tube inside was completely gone; only a
few scorch marks on the PCB and short wire stubs gave testimony of
the tube's previous existance.

I used the model 500 desk phone to call the fire dept. to come out
to inspect the roof, as there were burn marks visible on the roof
as well as a lot of smoke inside following the blitz.  Fortunately
there had been no fire.  Apparently the smoke was actually a lot of
soot that the lightning blew out of the chimney.

There's a chance a spike-damged modem might be covered under a
homeowner's policy, but with deductibles most 2400 bps modems would
probably be under the limit these days.

I had a couple of modems replaced under my homeowners policy without any
problems.  I have since put lightning protectors on the lines.
