Chapter 1 Getting to Know the IES-1248
Console Port
Use the console port for local management of the IES-1248.
Fans
The fans cool the IES-1248 sufficiently to allow reliable operation of the IES-1248 in even
poorly ventilated rooms or basements. To conserve energy and reduce noise, the fan speed
depends on the temperature.

IEEE 802.1p Priority
Your IES-1248 uses IEEE 802.1p Priority to assign priority levels to individual PVCs.
Multiple PVC and ATM QoS
The IES-1248 allows you to use different channels (also called Permanent Virtual Circuits or
PVCs) for different services or subscribers. Define channels
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).
