Abstract: A system and method for generating a frequency rich spectrum in a data stream is disclosed. A network interface comprises a substitutor module, a symbol replacement module, and an encoder module. The substitutor module replaces idle streams in a first data stream with alignment symbols, boundary symbols and disposable symbols to generate a second data stream. The symbol replacement module receives the second data stream, generates random data, and replaces one or more of the disposable symbols in the second data stream with the random data in order to generate a third data stream. The encoder module encodes the third data stream.

Abstract: The present invention relates to methods and apparatus for performing reverse auto-negotiation, in which one network device establishes a link with another network device at a preferred operating mode (e.g., the lowest speed) common to both devices without linking twice. The physical layer of a local network device (local PHY) may stall the normal auto-negotiation process with the link partner, while receiving the abilities of the link partner. The local PHY may then transmit a signal having only the preferred common operating mode (e.g., the lowest speed) encoded within. The link partner may then conclude that the local PHY is only capable of the preferred common operating mode (e.g., the lowest speed) and a link between the two devices may be established at that common mode.

Abstract: A network device includes a media access control (MAC) device that transmits a first data stream at a first data rate, the first data stream including first symbols having M bits. A translator converts the first data stream to a second data stream at a second data rate. The translator includes a data appender that appends N bits to the first symbols in the first data stream to generate second symbols having M+N bits. A data duplicator duplicates the second symbols X times to produce the second data stream at the second data rate. M and X are integers greater than one, and N is greater than or equal to zero.

Abstract: A network interface includes a physical layer (PHY) device that provides an interface to a cable. The PHY device includes an autonegotiation module that selectively performs autonegotiation to establish a link with a link partner based on link parameters and a cable test module that performs a cable test before the autonegotiation begins, that determines a cable performance parameter during the cable test, and that compares the cable performance parameter to a predetermined threshold. The autonegotiation module selects at least one of the link parameters based on the comparison.

Abstract: A network interface includes N input lanes that receive data symbols and idle symbols. A substitutor module periodically replaces an idle symbol on each input lane with a corresponding alignment symbol to form an alignment group. M interleaver modules each interleave a portion of the data symbols and alignment symbols onto a corresponding transmit lane based on an interleaving pattern that provides each transmit lane with N/M alignment symbols from the alignment group. M is an integer greater than 1 and N is greater than M. In some features the substitutor module periodically replaces successive idle symbols on each lane with alignment symbols to form corresponding alignment groups. An interleaver module interleaves the data symbols and alignment groups onto M transmit lanes according to an interleaving pattern that provides each transmit lane with one of the alignment groups.

Abstract: A resynchronization device for an Ethernet network device with a transmitter and a receiver includes a detector that detects faulty code groups received by the receiver. A counter counts the faulty code groups that are detected by the false carrier detector during a predetermined period. A resynchronization trigger asserts a resynchronization signal if the counter exceeds a predetermined threshold during the predetermined period. The faulty code groups include false carriers, which include non-idle code groups other than frame delimiters. Alternately, the faulty code groups include idle code groups that match idle code groups generated by the transmitter of the local network device.
