Assignee: MARVELL ASIA PTE LTD
Field: Digital communication (Electrical engineering)
Classification: CPC H  G  Y | IPC G  H

Claim 15:
16. A networking system within a closed operating environment, comprising:
a wired signaling medium;
a network hub comprising a First transceiver coupled to at least one bidirectional channel over the wired signaling medium; and
at least one network device, the at least one network device comprising a second transceiver communicatively coupled to the network hub via a respective bidirectional channel over the wired signaling medium,
wherein the network hub and the at least one network device are configured to communicate with each other over the bidirectional channel in a plurality of operating periods, the operating periods including
a first operating period in which the network device is configured in a data transfer mode to transmit data signals to the network hub along a downstream path over the bidirectional channel at a first signaling rate, and
a second operating period in which the network hub is configured in a low-power mode to transmit low-power refresh signals that are encoded with information to the network device along an upstream path over the bidirectional channel at a second signaling rate that is different than the first signaling rate, and

wherein the network device is configured to decode the information from the low-power refresh signals and is responsive to the information to control an operation of the second transceiver.
