<div dir="ltr">Hi All,<div><br><div>Just trying to understand something about NBN Traffic Classes.</div><div><br></div><div>As per NBN Product Tech Spec document:</div><div>

<p><span style="font-size:9pt;font-family:Calibri">"TC-4 is implemented as CIR at the CVC, meaning that CVC TC-4 capacity cannot be shared with other CVCs or traffic classes
across the NNI."</span></p>Which make sense, but then why you need TC-1 and TC-2 for a CVC? Is there any use case for that? Probably voice but then what is the impact of using a TC-1 AVC over TC-4 CVC? IMO the current congestion point is last mile only or its a wrong assumption?</div><div class=""><br></div><div class="">Anyone would like to share (offlist) if they are using any traffic class other then TC-4 (or generally unmarked) for CVC. </div><div class=""><br></div>
