APPARATUS, METHOD AND COMPUTER PROGRAM MEANS FOR DATA TRANSPORT WITH REDUCED POWER CONSUMPTION DURING LINK IDLE TIMES

The present invention relates to a method and apparatus for disconnecting a bias current circuitry (140) in a way that there is no bias current flowing anymore for the transmit output of a network controller (110), e.g. Ethernet controller. Also, the data connection, e.g., TX+ and TX− lines in or at...

Zusammenfassung:	The present invention relates to a method and apparatus for disconnecting a bias current circuitry (140) in a way that there is no bias current flowing anymore for the transmit output of a network controller (110), e.g. Ethernet controller. Also, the data connection, e.g., TX+ and TX− lines in or at an Ethernet connector (120), are connected to a control circuitry (130) to simulate an active connection by taking over supply of link activation pulses, e.g., link integrity test (LIT) pulses. These two measures will allow the user to save the bias current on the transmit output and maintain the link activation signals to keep the link up towards a network controller (110).
