Cable problems come in all shapes and sizes and from the logical to the weird. You wouldn't think that something fixed out of the way could get damaged but it does in a variety of ways.
Corrosion or wear.
In the seventies and eighties BT engineers used to use whatever cable they had available on their vans to cable jobs which sometimes resulted in internal cable being used outside and it is not uncommon to still see that nowadays. Cable which was only intended to be used internally suffers from being baked in the sun and frozen in the winter and can end up like my samples below.
Some cable goes very brittle and the insulation cracks off exposing the conductors underneath to exposure or moisture.
The wire below is named dropwire and is used to link the telephone pole to your house, it was used in the 1970's and 1980's. The wire had to have great strength and it is actually composed of copper coated steel wires sheathed in plastic insulation. But again the effect of years of the sun, frost and rain penetrate the insulation and the steel wire rusts shown by the brown stain and eventually it will crack the wire as in the examples below.
Once upon a time external cables used to be terminated externally under a screw but so often nowadays those very screws can be found suffering from corrosion which is no friend of a quiet phone line or broadband.
This box is certainly not from BT, more of a DIY arrangement but certainly not something that should be used outside.
Usually external cable is joined using silicon filled crimps but the ones below have seen better days.
Pets can influence internal or external cabling especially new puppies who love to chew things like telephone cables in my experience. In the case below the puppy chewed every scrap of cable that was within its range. That has not been a one off as I have been to several homes where puppies have taken a liking to telephone cables.
Rats or mice do also like the taste of telephone cable and it isn't impossible that some damage is down to them.
The human animal is sometimes just as liable to cause damage to telephone wires when tidying in the house or garage. I have attended situations where the house holder just thought they would remove that unsightly cable only to find the phone or broadband went off afterwards. Or a lawnmower driven too close to the corner of a wall just nicked the external telephone cable at wheel height.
Then there is the enthusiastic Hedgetrimmer user. Sometimes telephone cables are excellently camouflaged as bits of ivy or creepers when one is tidying up around the house, so be wary! Phones work on 50 volts and there is not much chance of causing yourself damage from the cable but you are likely to get severely embarrased when you call me to get the cable repaired. A few examples from my archive of damage below:-
Anyway no matter what other damage occurs I don't think I've ever seen worse problems than those caused by electricians!
