 +The underground ducting is tapped off to each subscriber'​s house with a "swept tee" pipe connector, the side arm of this is brought out to a junction box in the pavement adjacent to the house boundary. When a subscriber is activated, a smaller duct is run from the box pictured to the house and a coax/​twisted air cable is pulled through from the house to the street cabinet with the taps in. 
  
-Incoming underground coax is fed to an outside unit where the rf signal can be attenuated if required and split to feed extra set top boxes or DOCISS internet modems, and the POTS telephone service can be brought in to the house. The coax cable is then passed through an isolator to keep any dangerous voltages from passing back to the network in case of a fault on the subscriber side. \\+The original boxes were cast metal, subsequently rollouts used plastic.
