time data (such as audio and video).
In this application, we demonstrate how to set up the multiple PVCs environment.
From the figure below, the PC wants to access the two kinds of network services. One
is the Internet service (data service) and the other is Video service. Because we hope
we can see the video smoothly, we need to set the video service higher priority. In
IES-1248-51V, we can set the two services with different VLANs and assign the
PVCs with different VLAN, priority and ATM QoS. That will make the video traffic
get the higher priority than data traffic. We also can expand this application to triple
play environment.

Following procedures will introduce the settings of IE
switch and ADSL CPE. We use ZyXEL ES-2024 and Prestige 660R-61 as
VLAN-aware switch and ADSL CPE, respectively.
