That shouldn't make any difference at all. Just because it doesn't happen when they are there, doesn't mean it's not happening at all.

We use a system down here called Cheetah! I believe most areas should have it in place. When we got to a customers house we send back carries to a guy monitoring the system and he tells us what levels he is seeing them at. Then it's a case of breaking things down and sending the carriers back from different points of the cable run. That way it tells us where the fault lies, be it internally, at the ETB (fromt of the house) the cab or further back into the system
