Triple play Application (with ALC/SLC Line Card)
On the IES-5000, you can use different channels (also known as Permanent Virtual
Circuits or PVCs) for different services. Define channels on each DSL port for
different services and assign each channel a priority, VLAN and ATM Quality of
Service (QoS). The ATM QoS allows you to regulate the average rate and fluctuations
in data rates. This helps eliminate congestion and to allow smooth transmission of real
time data (such as audio and video).
In this application, we will show you how to set up multiple PVCs using the IES-5000.
The following figure shows a network example where the computers want to get
different services (data service for Internet access and video service) from two
networks. Since a smooth video streaming quality is desired, we want to give the
video service a higher priority. To do this on the IES-5000, create a different VLAN
for each service and configure the PVCs with a different VID, priority and ATM QoS.
This allows the video service to have a higher priority over the data service. You can
easily adapt this application for a triple-play service network.
