摘要： A method and system for a multi-rate Media Access Control layer (MAC) to Physical layer (PHY) interface is provided. The method to provide a multi-rate Media Access Control layer (MAC) interface comprises receiving a first set of signals, sampling the first set of signals to determine a type of interface to be used to transmit or receive the first set of signals or a subset of the first set of signals, generating a select signal indicating type of interface to be used based on the sampling step and transmitting the first set of signals or a subset of the first set of signals using the interface indicated by the select signal. The method to provide a multi-rate Physical layer (PHY) interface comprises receiving a select signal from a Physical layer (PHY) layer indicating data rate of a first set of signals, selecting a first interface and turning off the second interface if the select signal indicates the first interface is to be used, selecting the second interface and turning off the first interface if the select signal indicates the second interface is to be used and transmitting the first set of signals using the second interface or a subset of the first set of signals using the first interface based on the select signal.

摘要： A method and apparatus for generating a performance indicator in a high-speed communication system. A plurality of disparate communication status signals with differing formats from a transceiver are combined in a logic module to create a single link quality indicator signal. The link quality indicator signal is used to encode different operational states of the transceiver from fully operational, to marginally operational, to failed. The link quality indicator signal is advantageously employed to drive a LED creating a visual performance indicator.

摘要： Methods and systems for operating a physical layer device (“PHY”) in an Ethernet network include methods and systems for detecting active link partners and for selecting a mode of operation based on detected active link partners, without user intervention. The PHY monitors fiber link media and copper link media for active link partners. The PHY selects a mode of operation according to detected active link partners. For example, a serial gigabit media independent (“SGMII”) mode of operation is selected when an active copper link partner is detected and an active fiber link partner is not detected. Similarly, a serialize/deserialize (“SerDes”) pass-through mode of operation is selected when an active fiber link partner is detected and an active copper link partner is not detected. The PHY interfaces with the active copper link partner when the SGMII mode of operation is selected. Conversely, the PHY interfaces with the active fiber link partner when the SerDes pass-through mode of operation is selected. The SGMII or SerDes pass-through mode of operation can be prioritized for when active copper and fiber link partners are detected. The prioritized mode can be user selectable or factory set. The invention optionally powers down circuitry associated with an unselected mode of operation.

摘要： A communications network includes a management device and a remote device. The remote device includes a physical layer device (PHY) coupled to a link partner. An independent station manager of the remote device provides the bi-directional exchange of management information between the PHY and a serial-to-parallel (S/P) interface connecting the remote device and the management device. A station manager of the management device provides the bi-directional exchange of management information between the S/P interface and a Media Access Controller (MAC) of the management device. The independent station manager and the station manager transmit initiation messages, formatted according to a message template of an Auto-Negotiation (AN) routine of the S/P interface reserved for customization, to reserve an embedded management channel for the transfer of management information. Management information messages, formatted according to a message template of the AN routine, are subsequently exchanged, thereby providing Auto-Negotiation of the PHY.
