Chapter 1 Getting to Know the IES-1248-51 39
IEEE 802.1p Priority
Your IES-1248-51 uses IEEE 802.1p Priority to assign priority levels to individual PVCs.
Multiple PVC and ATM QoS
The IES-1248-51 allows you to use different channels (also called Permanent Virtual Circuits
or PVCs) for different services or subscribers. Define channels
1
on each DSL port for different
services or levels of service and assign each channel a priority. ATM Quality of Service (QoS)
allows you to regulate the average rate and fluctuations of data transmission. This helps
eliminate congestion to allow the transmission of real time data (such as audio and video).

The IES-1248-51 supports the IEEE 802.1x standard for centralized user authentication and
accounting management through an optional network authentication (RADIUS) server.

VLANs on specified ports.
