    摘要: A triggered restart mechanism for failure recovery in power over Ethernet (PoE). Powered devices (PDs) that fail can be remotely recycled by a power sourcing equipment (PSE). After detection of a failure of a PD, such as by the failure to receive a status message, a PSE can generate a reset signal (e.g., power cycle, reset pulse, etc.) on the port. This reset signal can cause the PD to perform a full power cycle or quick restart.

    摘要: A system and method for using an Ethernet physical layer device to identify cabling topologies. A power sourcing equipment (PSE) can power independent powered devices (PDs) using two sets of wire pairs in a single four-pair cable. Higher power PSEs can power a single PD using all four wire pairs in the cable. Conventional power over Ethernet (PoE) analog techniques (i.e., voltage, current, etc.) have a difficult time distinguishing where the wire pairs are going from the PSE. By using information (e.g., negotiated speed, link energy, distance diagnostic, etc.) generated by the physical layer device (PHY) subsystem, the PoE system can determine whether the two sets of wire pairs in a cable are powering a single PD or two independent PDs.

    摘要: A system and method for using a link energy signal in physical layer devices (PHYs) having a silent channel/interface in energy efficient Ethernet (EEE). LPI modes in EEE suffer deficiencies in cable unplug detection due to the latency in refresh cycles. LPI modes in EEE also suffer from potential frequency drift, which leads to high bit error rate (BER) when coming out of LPI mode. A link energy signal transmitted during LPI modes enables real-time detection of cable unplug and the frequency lock to be maintained.

    摘要: A power over Ethernet (PoE) power sourcing equipment (PSE) architecture for variable maximum power delivery. PoE PSE subsystems rely on some control to “turn on” a power field effect transistor (FET), which allows current to be transmitted to a powered device (PD). A hybrid approach is provided where an internal FET can be augmented with an external FET to provide an architecture that can be flexibly applied to applications with various space, cost and cooling limitations. The maximum delivered power can also be boosted with the addition of an external FET to the internal FET.

In this regard, an Audio Video Bridging timeslot may be designated for handling an energy efficient networking (EEN) transaction and the EEN transaction may be performed during the designated timeslot. Exemplary EEN transactions comprise scheduling a data rate transition, transitioning to a different data rate, training a link partner, and exchanging training related information. It may be determined whether the timeslot may be reserved for conveying an AVB stream prior to designating the time slot for an EEN transaction. In instances that the timeslot may be unreserved, the timeslot may be reserved for EEN transaction(s). Information exchanged during the designated timeslot may enable scheduling a data rate transition and/or training on a network link. In this regard, a subsequent timeslot may be designated for the data rate transition and/or the training.

    摘要: An Ethernet link may comprise silent and active channels and may support energy efficient Ethernet communication. Training parameters from the one or more active channels may be utilized for determining and/or adjusting training parameters for silent channels prior to activation. Training parameters for silent channels may be determined based on copying training parameters from active channels. Determination of training parameters for silent channels may be based on a weighted average of the active channel training parameters. A delta between active channel training parameters from a prior time and subsequent time may be utilized to determine a correction factor for adjusting training parameters for a silent channel from a prior time. Silent channels may be adjusted based on active channel training parameters and then subsequently may be trained. Training parameters may be adjusted for one or more of an echo canceller, a near-end crosstalk canceller and a far-end canceller.
