NTD

Network Termination Device is a device or connection point that defines the demarcation point between a carrier network and the building or premises cabling. An NTD in a FTTP network this is typically an Optical Network Terminal (ONT). An NTD in a traditional copper telephone network this is a connector located in a small enclosure on the external wall of a single premises or on the “A-side” of the Main Distribution Frame (MDF) of an apartment building or MDU.

ONT

Optical Network Terminal is a network termination device (NTD) for a Fibre to the Premises (FTTP) GPON network that converts light signals to and from the telecommunications carriers’ fibre optic cable network to electrical signals suitable for the premises copper cable network.
