11.23.3.3 ADSL Mode: 2 PVCs in WRR Example
In this example the subscriber is located farther away so there will often be less bandwidth actually
available. 2 PVCs and WRR help ensure that both video and data traffic get through. The backbone
network and the system use IEEE 802.1Q VID 2 for video and VID 3 for data. The VLC1348G in slot
6 has VDSL port 3 connected to an ADSL2+ device and uses VPI/VCI 0/34 for video and 0/35 for
data. Data and video are each allocated 5.12 Mbps. Since video is more delay-sensitive than data,
the weight on 0/34 is set to 60 and the weight on 0/35 is set to 40. This means that video traffic
will get more service, but data traffic can still get through.

Here’s how to configure port 3 to use these settings.
