VM was installed in the street while I have been living here. No box has been added to my terraced house outside or inside. The brown cable in (which was here when I moved in) has exactly the same connector as the isolator cable (I.e. a pin not a hole for the pin). Please advise.
Sounds like you need an engineer to install a cable from the street to the property. If you have been living in the property whilst the cable in the street was laid, and never been a customer to Virgin before. When VM install cable to the street, they don't put boxes on the wall until the occupants become a customer. This seems to be the case here.
