IES-1248-51/51A/53 User’s Guide
42 Chapter 1 Getting to Know the IES-1248
Integrated Splitters
The integrated DSL splitter eliminates the need to use external splitters that separate the voice-
band and ADSL signals.
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.
