<div class="yiv5966233266MsoNormal">Hi Everyone,</div>
<div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23629"> </div>
<div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23583">We have been battling an NBN fault (new service) for a customer for the past 2 months – Basically seeing copper-side interface down from our router to the NTD at roughly the same times each morning (NBNco have replaced the NTD & power supply,
we have replaced our router & cabling).</div>
<div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23589"> </div>
<div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23590">NBNCo and the provider (iinet) seem to have zero visibility into fibre link state – With the only diagnostics available from anyone at iinet being the IPoE session times, which do not reliably drop when the router to NTD link drops.
</div>
<div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23591"> </div>
<div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23592">Despite multiple escalations to the iinet fibre team, we can’t get an answer to this question: Will a fibre link disruption be reflected on the copper side of the NTD? (Without knowing that much about the post-NTD side of the NBN network,
is there FEF/link state pass-through/some other mechanism by which the NTD would shut down UNI-D ports in response to a fibre-optic fault somewhere between the CPE and the PoI?)</div><div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23592"><br></div><div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23592" dir="ltr">/ iiNet should be escalating that to NBNco if they don't know the answer to that question, it is their (NBNco's) equipment. NBNco should be the experts on NTD behaviour and capabilities.</div><div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23592" dir="ltr"><br></div><div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23592" dir="ltr"><br></div>

<div class="yiv5966233266MsoNormal" id="yui_3_16_0_1_1428898150946_23755">Excuse my question if this information is available somewhere obvious – I have done a fair bit of research online and not been able to uncover an answer.</div>
