摘要： Aspects of a method and system for an extended range Ethernet line code are provided. A local PHY may enable converting Ethernet media independent interface (MII) data from a 4-bit packet stream to a 3-bit packet stream. The 3-bit packet stream may be mapped to first and second ternary bits streams, for example, for communication to a remote PHY utilizing PAM-3 over one or more twisted-pair wires. The 3-bit packet stream may be scrambled and/or aligned before mapping. When a single twisted-pair wire is available, the local PHY may multiplex the ternary bits streams into a single stream. Start-stream delimiters (SSD) may be inserted before the ternary bits streams and end-stream delimiters may be inserted after the ternary bits streams. Idle signals may be inserted after the ESDs and before the start of the next frame of MII data.

摘要： Aspects of a method and system for an extended range copper transceiver are provided. Reducing the communication rate provided by multi-rate physical (PHY) layer operations in an Ethernet transceiver may extend the range of the Ethernet transceiver over twisted-pair copper cabling from a standard connection length. The Ethernet transceiver may support up to 1 Gbps or up to 10 Gbps transmission rate over copper cabling. The multi-rate PHY layer architecture in the Ethernet transceiver 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 multi-rate PHY layer operations. Reducing the communication rate may also enable utilizing greater insertion loss cabling for a standard connection length.

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： The present invention relates to a system for processing a lipophilic fluid, more particularly to a system for processing a lipophilic fluid utilized in a fabric treating process, even more particularly to a system for processing a lipophilic fluid such that contaminants such as water, surfactants, water, body/food oils, fatty acids, and dyes can be removed from the lipophilic fluid. In other words, the present invention relates to the “cleaning up” of or purification of a lipophilic fluid such that it can be re-used in a lipophilic fluid system.

摘要： Construction of LDPC (Low Density Parity Check) codes using GRS (Generalized Reed-Solomon) code. A novel approach is presented by which a GRS code may be employed to generate a wide variety of types of LDPC codes. Such GRS based LDPC codes may be employed within various types of transceiver devices implemented within communication systems. This approach may be employed to generate GRS based LDPC codes particular designed for various application arenas. As one example, such a GRS based LDPC code may be specifically designed for use in communication systems that operate in accordance with any standards and/or recommended practices of the IEEE P802.3an (10GBASE-T) Task Force.

摘要： A method, system and computer program product to adjust transfer rates on conductors in a multi-conductor cable comprising monitoring signals received on each conductor, determining a Signal to Noise Ratio (SNR) for each conductor and adjusting a transfer rate on one or more conductors based on the corresponding SNR. In an embodiment the multi-conductor cable is a twisted pair Ethernet cable. The method further comprises determining whether a conductor is transmitting at an optimal transfer rate as a function of its SNR, calculating an optimal transfer rate for each conductor as a function of its SNR and periodically measuring a change in SNR on each conductor. If the change in SNR is greater than a predetermined threshold, then the transfer rate is re-calculated for the conductors requiring transfer rate adjustment as a function of SNR.
