The NBN is Australia’s National Broadband Network; a primarily-fibre network with last-mile copper in most places. As explained here, NBN connections are divided into 7 types – FTTP (Premises), FTTB (Building), FTTC ("Curb" or Street pit), FTTN (Node), and HFC (Hybrid Fibre Coaxial), Fixed Wireless, and Satellite. Unfortunately, each type has its own quirks and requirements. This question is about FTTC (and possibly others), which consists of a fibre link to a pit outside the premises, and existing copper (previously ADSL) from the pit to the premises’ original telephone line.

For FTTC connections, an "NBN Connection Box" is provided by NBNCo, usually along with an "NBN-approved" router (by your ISP, for an additional cost). There has been mention that connecting without an "NBN-Approved" modem may cause your NBN connection to be blacklisted (time-delay) but this may only apply to directly-fibre based connections. It’s unclear if this applies to FTTC connections.

This question is related to this question about the function of the NBN Connection Box on an FTTC connection.

In it, the top answer says about the "NBN Connection Box":

More specifically, it is a VDSL2 modem preconfigured for NBN FTTC. Like any other modem, it acts as an interface between the analog signal travelling along the copper pair (your house lead-in) from the DPU in the pit, and an Ethernet network.

So, if it is a VDSL2 modem and, specifically, an ethernet on the other side, other than sharing the connection why do we need a router in this diagram?

Let’s say I don’t want to share or to provide Wi-Fi or some other telephone. I just want a wired NBN connection to my PC. If the ethernet cable is really ethernet, can I safely do this?

The only other thing I can see is:

  • the authentication requirement (PPPoE)
  • the "NBN-Approved" requirement for the router (if it exists for FTTC).

So, is it possible to wire it this way (without a router) and then use PPPoE in software over an ordinary Gigabit LAN adapter?

If so, how? (I am proficient in Windows, Linux, and Mac networking, so I can translate any solution between the three. Any suggestion will do.)

If not, why not?
