Hi all

I have a second telephone cable run from the master box in the downstairs
hallway, all the way to my distribution point in the loft.
This I intend to use for unfiltered signal when broadband is installed.
Pulling some power cables recently along a similar route, I noticed that the
second telephone cable had been "dented" and was scorched on the opposite
side to the dent impact over about an inch of its length.
This has obviously been the work of plumbers who upgraded the ch recently
despite my urgings to them to take care of cabling.

So, the question, can I test the cable somehow to make sure its OK?
Will mean lifting lots of floor again to replace cable at this stage.

TIA

Phil
