cable from the street runs up and seems to be split in 2.
one goes into a single connector which then runs into the house at the hub. Landline goes through the hub.
the other half of the cable from street is then connected with some loose wires (the ones wrapped around the thin black cable in picture) that runs along front of house and into side of a study (never used since i been there)
The white cable through the splittter seems to head off up into the loft but unable to chase it further in the loft (perhaps it goes to the aerial in teh loft), the black cable in the splitter runs into the side of study.
in the study there is old phone/ntl boxes, none working and when engineer originally fitted virgin said that they weren't operational.
