nicks: We had fibre installed today. The Chorus technicians tested web browsing and did speed tests with a laptop plugged directly into the ONT. So it is definitely possible. Connection is with Telecom.
We only telnet into the ONT to set its ID - there is no other setings that can be changed on the ONT localy - updates of the firmware are done remotely via the fibre connection.
End user internet access/speed checking is done via the router (RGW) and not directly via the ONT - there is no point as testing directly as compliance testing is via the providers equipment .
