I have just moved into a new home however it appears there isn’t any telephone connection to the house.
There’s a black cable that comes out a conduit from underground, and another single blue Cat5 cable that ties to another small-ish cupboard central of the house with more Cat5 cables which links to the various rooms.
Pictures here:



Just wondering what is needed to be done to have POTS service established?
I note there isn’t any ETP box on the exterior of the house.
Many thanks in advance guys.
