There's a big if about record-keeping for splitter ports here, but it's not technically impossible."</div></div></div></div></span><div><br></div><div>You would need to do a physical one-by-one serial disconnect of every port on the PON span whether there it is an active port or not (including never connected) because anyone can simply plug into any port on that PON span. There is some logic you can apply to help order of disconnection during trouble shooting to minimise disruption if you have good logs and even better if you control ONU, a point that's probably not lost on NBN Co.</div><div><br></div><div>Cheers</div><div><br></div><div>[b]</div><span id="OLK_SRC_BODY_SECTION"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div style=""><br></div></div></div></div></span></body></html>
