Just after a bit of advice. A numpty in the house may, or may not of cut off a BT junction box where the dropwire comes into the house to do some decorating... Cutting the dropwire back so it's flush with the hole in the wall where it enters the house.
Would it be possible to buy some internal wiring(as this is also now too short to be fed through the hole to make a connection outside) and connect it straight to the dropwire so that the connection goes from the dropwire, straight into the new internal wiring that then goes into the NTE5?
I'm thinking of soldering the cables together and then using some heat shrink tubing on the A and B cables and then again over the external cover for both cables to make it watertight as this will be on the outside of the house.
