 +Another smaller cabinet, rather too full maybe. This was left with the cover off until I replaced it. The cover in the pavement links the cabinet to the underground ducts. This is a single duct with a swept Tee to link off to the subscribers premises.

 +===== Subscriber side =====
  
  
 +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. \\
