摘要： Certain aspects for the start-up procedure of transceivers supporting higher data rates over twisted-pair copper cabling are provided for 10 Gbit/sec Ethernet links (10GBASE-T). During a PMA (physical medium attachment) training period of the start-up procedure, long PMA training frames are exchanged periodically between link partners. A significant portion of each PMA training frame consists of known pseudo random sequences simultaneously transmitted over four wire pairs. PMA training frames include an InfoField for exchanging parameters and control information between link partners. For example, the InfoField's payload comprises fields for indicating current transmit power backoff (PBO), next PBO, requested PBO, transition count, control information, and for communicating precoder coefficients. Information in InfoFields is repeated and is not necessary that a link partner decodes every InfoField. For example, by occasionally reading the transition count, a link partner can determine when a change in transmit PBO and/or a state transition is to occur.

摘要： A system and method for enhanced physical layer device autonegotiation. The autonegotiation process typically identifies the highest common denominator amongst various standardized modes of operation. Enhanced autonegotiation can be used to select a mode of operation that is not the highest common denominator. Enhanced autonegotiation can also identify a non-standardized mode of operation using next page messaging, additional physical signaling, or Layer 2 messaging.

摘要： Aspects of a method and system for an asymmetric physical (PHY) layer in extended reach Ethernet local area networks (LANs) are provided. Reducing the communication rate provided by an asymmetric Ethernet multi-rate PHY may extend the standard distance over twisted-pair cabling where customer premises equipment (CPE) may be located in the MTU. Downstream and upstream rates may be aggregated evenly or unevenly over each twisted-pair wire in the copper cabling. The asymmetric Ethernet multi-rate PHY may support signal-processing operations, such as echo cancellation and/or equalization, which may be applied to the reduced communication rate to enable range extension. The reduced communication rate may be achieved by reducing the symbol rate provided by the asymmetric Ethernet multi-rate PHY. Reducing the communication rate may also enable utilizing cabling with greater insertion loss than those used for a standard connection distance.

摘要： A system and method for achieving higher data rates in physical layer devices. Costs imposed by large data rate increases represented by generational increases in Ethernet standards activities are avoided through physical layer device modifications that enable marginal increases in data bandwidth. Building-block reuse can be promoted through the selective use of clocking rate increase, increase in coding efficiency, and bit reuse.

摘要： A system and method for energy savings on a PHY/MAC interface for energy efficient Ethernet. Power savings for a PHY due to low-link utilization can also be realized in the higher layer elements that interface with the PHY. In one embodiment, subrating is implemented on a MAC/PHY interface to match a subrating of the PHY with a remote link partner. This subrating is less than the full capacity rate and can be zero.

摘要： Aspects of a method and system for adaptive tone cancellation for mitigating the effects of interference are provided. In this regard, an Ethernet PHY may receive one or more signals via a corresponding one or more physical channels and generate one or more estimate signals, each of which approximates interference present in a corresponding one of the received signals. The Ethernet PHY may subtract each one of the estimate signals from a corresponding one of the received signals. The subtracting may occur at the input of one or more slicers in the Ethernet PHY. The received signals may be processed via one or more equalizers in the Ethernet PHY. A decision output of a slicer in the Ethernet PHY may be subtracted from one of the said one or more received signals, and a signal resulting from the subtraction may be utilized to generate the one or more estimate signals.
