I’m pretty sure that as a layer-2 device, there is no account/premises specific
configuration in NCDs. When NBNco swapped mine over, they just took one out of
their van and I plugged it in. DPUs may be a different kettle of fish but the
general public shouldn’t be touching these!

OK - NBNco has visited, replaced my NCD (with another Netcomm for better or
worse) and took a look at the DPU. They have also removed the bridge back
to the copper PSTN (they said that some surges or hits can cause the DPU to
switch the circuit back to the PSTN and not revert to the NBN!).
Hi Chris - Hope you're well.
My (inner city) FTTC service was extremely unstable after it was first
delivered. Lots of short duration drop outs. Not good for Zoom meetings
when working from home. It took 5 separate NBN tech visits to resolve the
problem over two months. We also had to "phone a
Hey Chris (legend). Get a Starlink backup. Better than 4G from a GB quota and
bandwidth perspective in remote areas.

A. Ensure your legacy phone line was cut out of the CIU in the pit/pole - and
also the other three neighbors connected to the DPU.
B. Put your NCD and phone line on a surge protector.
C. Try and get the more hardy
If you are getting a RED LINK LIGHT on the NCD, then there is a fault where
it cannot supply reverse power to the DPU.
Either a DPU or NCD fault, requiring the RSP to log a fault with NBNCo to
investigate.

BTW, I’m getting a red flashing link light on the NCD but if I unplug it from
the wall, the link light changes to blue (still flashing) so it seems to be
talking to the DPU, but maybe getting some fault indication?

Hi Greg,
Thanks for the info (a fair bit I was already aware of though) but up where
I am, pretty much everyone has their own DPU (big properties along a dirt
road. No concern with pits full of water though - everything is on power
poles including the DPUs and the fibre that connects them back
Hi Chris,
The nbn DPU (the "mini-vdsl/gfast dslam" which lives in the pit) is reverse
powered (about 6-14W) from the NCD (the nbn box inside your house). nbn use a
mix of Netcomm and more recently Nokia DPU's. The DPU only needs 1 customer NCD
connected to it to supply the power.
The DPU can
