Abstract

To reduce power consumption of a communications interface between a network and a processor, a method for controlling the interface monitors data traffic from sides of the interface (21). Upon detecting a predetermined period of no data traffic on both sides (23), the method disables an auto-negotiation mode (24) of the interface and forces the interface to operate at its lowest speed.
