This section is laid out in the manner in which the overhead plant is used.

The section starts where the underground cable terminates and is firstly connected to the overhead wiring.  This would be a distribution point or in the early days the exchange gantry.  This section stops when the external cable meets premises internal cabling.  In the past a Protector would have been installed in the premises, but today it is the Network Connection Point (NTP), which supports little or no protection.
