Network termination devices provide multiple bridges for customers to access the NBN.
Depending on the kind of link, NTDs typically provide two telephony and four data channels.
FTTC requires power to be provided from the premises to the kerb (distribution point).
FTTN networks, based on VDSL2 technology, can be accessed with any compatible modem or router that supports VDSL2.
The network termination used in the specific case of an ISDN Basic Rate Interface is called an NT1.
