Abstract
In an electronic system for the transmission of data between a number of stations, sub-system operation can be achieved by a suitable choice of signal levels and wake-up levels, so that some of the stations can communicate with one another while other stations are in a sleep mode in which power is saved.
Claims6
A transmission system comprising:
- a plurality of stations, wherein the stations have a passive mode and, in response to a wake-up signal, an active mode, in the active mode information is transmitted using at least two different voltage levels, and
- wherein the wake-up signal is transmitted using a third voltage level which lies outside the at least two different voltage level range for the transmission of information, and allows active stations to communicate with each other without waking passive stations.
A station for use in a transmission system having a plurality of station, the station comprising:
- a receiver for receiving data signals, using at least two different voltage levels,
- wherein portions of the station are switchable to a passive mode in response to a wake-up signal and enables all portions of the station to an active mode, wherein the wake-up signal is transmitted using a third voltage level which lies outside the at least two different voltage levels for the reception of information, and allows active stations to communicate with each other without waking passive stations.
