The outside copper plant is composed of the following networks:

  • Trunk network, which connects the Centrals
  • The Principal network – the network that connects a node called the district node to the Central
  • Secondary network – the network that connects the district to the terminals near the client’s domicile
  • The client’s network is the network that goes from the outside terminal, by means of a descending cable, to the device inside the client’s domicile.
  • Direct network – the network that directly distributes the energy from the Central to the terminals.
