    <div class="moz-cite-prefix">TC2 and TC1 can be very sensitive to
      arguably overzealous policing, requiring tight shaping at the NNI
      (POI) and attention to Ethernet buffering, burst limits and
      inter-packet gaps or packets will be dropped.<br>
      Usually voice traffic on TC1 doesn't tickle the policing  though
      as the VoIP CODEC naturally leaves good spaces between the
      packets. Data packets at TC2 different story.<br>
      Check packet-loss during the throughput tests, in each direction
      independently if you can - overzealous inbound policing or
      inadequate outbound shaping will result in packets being tossed
      due to micro-spikes in traffic, even when the long-term average
      should be below the policing threshold - and that might be between
      your upstream and the NBN kit at the POI, than between you and
