JC>> Sure.  If you have a Telstra box on the wall containing one or two

JC>> I think Critec make something similar.  These should be familiar

PL> I think it might be frightening to ask the price for one of these... :)

I nagged until I got one from the installation crew.  They got back - put
in the earth stake, fitted the arrestor, then put in a plastic box with no
return path for the earth from the center lug.  Useless...:-(

Telstra.

JC>> What you need is a 3 pole arrestor.  These have a common chamber so

PL> Is this a gizmo about 2cm by under 1cm dia? I was given one, told it was 
PL> for protecting the phone line, but couldn't see how it worked...

It's a gas discharge gadget.  Three legs, cylindrical body.  Either side
flashing over ionizes the lot and shorts both sides to center.  Providing
you have kind enough installers to connect the center to something useful,
this is good..

The Krone magazine is 10 of those in a row.
