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, 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.
How to set up a Multiple PVCs environment.
Following procedures will introduce the settings of IES-1248, VLAN-aware switch
and ADSL CPE. We use ZyXEL ES-2024 and Prestige 660R-61 as VLAN-aware
switch and ADSL CPE, respectively.
1. IES-1248 Settings
1.1 VLAN setup
We can set up VLAN like procedure described in VLAN application. Add VLAN10.
Assign Port 1, ENET1 to be members of VLAN10 as show. We need to check the
Tx Tagging
on ENET1.
