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. <span style="background-color:rgb(255, 255, 255);display:inline !important">The
DPU only needs 1 customer NCD connected to it to supply the power.</span></div>

The DPU can connect up to 4 premises and the interesting thing is that any of the RSP's who have a customer connected to the DPU can initiate a DPU reset via the nbn API.</div>

So, you might be with Telstra, and your neighbours with Aussie Broadband, TPG and Optus and any one of them can essentially cause your service to drop momentarily if they contact their RSP who initiates the DPU reset as part of the troubleshooting.</div>

We've found that the DPU's often suffer the same fate as the old ADSL copper services when the pit fills up with water, the DPU goes off to la-la land (who would have thunk power and water didn't mix!) or the copper between the DPU and the customer gets corroded
and needs to be cleaned up or replaced.</div>

I've not heard of power issues causing the DPU to have issues. It sounds like the DPU is perhaps losing its config when there's a power interruption (we've certainly seen that with the Telstra EA MRV OS904 NTU's over the years).</div>

<b>Subject:</b> [AusNOG] NBN FTTC services and power hits</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">Is there anyone from NBNco on this list willing to discuss this with me?<br>
<br>
It seems that every time there is a power hit in our locality (which with Ausnet is pretty regularly), the FTTC services die and don’t come back until you log a fault through the provider (in my case, Telstra) and then wait for them to go through the hoops
of dealing with NBNco.<br>
<br>
This has happened four times in the last couple of months (thankfully I have 4G backup). There must be some aggregator kit that has no power backup or cannot recover from power outages - pretty crap really. :-|<br>
<br>
Sorry if this is a little OT for the list but I’d be interested if other FTTC areas see the same problem.<br>
