7.8.3.3 TC-4 Traffic Performance Characteristics<br />
Traffic class 4 is designed for applications that can benefit from a peak capacity, and tolerate variable<br />
throughput. TC-4 offers capacity as a PIR only.<br />
<strong>NBN</strong> <strong>Co</strong> does not provide specific Frame Delay, Frame Delay Variation or Frame Loss targets for the<br />
TC-4 traffic class.<br />
50 Note that individual Media Streams must operate within their configured peak bandwidth.<br />
51 This is the reference condition for TC-MC traffic performance, as measured at the NNI. TC-MC service frames are accepted<br />
up to the maximum frame size as described in section 7.7.<br />
