Abstract: Examples described herein relate to a network interface comprising physical medium dependent (PMD) circuitry, the PMD circuitry to during link training of at least one lane consistent with IEEE 802.3, exit to TIME_OUT state during TRAIN_LOCAL state based on consideration of expiration of a wait timer, loss of local_tf_lock state, and loss of remote_tf_lock state. In some examples, during link training for at least one lane consistent with IEEE 802.3, the PMD circuitry is to exit to TIME_OUT state during TRAIN_REMOTE state based on consideration of expiration of a wait timer, loss of local_tf_lock state, and loss of remote_tf_lock state. In some examples, link training consistent with IEEE 802.3 comprises performance of the PMD control function in Section 162.8.11 of IEEE 802.3ck.

Abstract: Methods and apparatus for register Read and Write operations over Auto Negotiation Next Pages. Register Reads and Writes are implemented using sequences of Auto Negotiation (AN) Next Page messages. The embodiments define mechanisms to use AN Next Pages to carry write and read instructions. It defines a bi-directional communication mechanism to allow writes to be confirmed and read data to be returned to the requestor. Sequences of several AN Next Pages are used to assemble full address and data fields, when necessary. Two link partners (endpoints or an endpoint and an intermediate partner) exchange AN Next Pages with address and data information. The method uses a unique device address assigned to each device discovered in the serial chain to enable write and read operations to specific devices.

Abstract: Technologies for autonegotiation of communications operational modes over copper cable include a network port logic having a communication link coupled to a remote link partner. The network port logic may start an autonegotiation protocol upon reset, when the link is broken, or upon manual renegotiation. The network port logic transmits an autonegotiation page to the remote link partner that indicates single-lane communications ability over copper cable. The network port logic receives an autonegotiation page from the link partner indicating single-lane communications ability over copper cable. If the network port logic and link partner have a common single-lane communication ability, the link may be activated. The autonegotiation pages may be base pages or next pages. The single-lane communication ability may be indicated by one or more bits of the autonegotiation pages. The link may be established at 1 gigabit or 10 gigabits per second. Other embodiments are described and claimed.

Abstract: One embodiment provides an apparatus. The example apparatus includes a root mean square (RMS) distortion determination module configured to determine an RMS distortion error and a signal to noise and distortion ratio (SNDR), the RMS distortion error determined based, at least in part, on a portion of a transmitted pulse centered at or near a transmitted pulse maximum amplitude and the SNDR determined based, at least in part, on the RMS distortion error.

Abstract: Methods, apparatus and systems for implementing Physical Media Attachment (PMA) alignment and rapid transition from a link training mode to a data mode for next-generation high-speed Ethernet links including a 100 Gbps Ethernet link. Training frames are transmitted between first and second Ethernet interfaces on opposing ends of the link in a pair-wise manner, with a first training frame being sent from a first Ethernet interface and a second training frame being returned from the second Ethernet interface. The training frames have a length that is different that the length of Physical Media Attachment (PMA) frames, and the returned training frames include receiver readiness status indicia identifying a readiness status of a local receiver port, frame alignment offset data identifying a relative offset between a training frame and a predetermined location in a PMA frame, and countdown data.

Abstract: Apparatus, systems, and methods for resolving a forward error correction (FEC) protocol include requesting, by a network node element during an auto-negotiation period between the node element and a link partner, to resolve at least one FEC mode during a data mode period, wherein auto-negotiation period occurs before the data mode period. At least one channel quality parameter of at least one channel of a communication link between the network node element and the link partner are determined by the network node element during the data mode period. The network node determines, during the data mode period, whether to enable or disable at least one FEC mode for use by the network node element based on, at least in part, the at least one channel quality parameter.

Abstract: Loop timing is performed in a Reconciliation Sublayer (RS) so that the transmit clock frequency can be adjusted to be equal to the receive clock frequency for the entire PHY (including the physical coding sublayer (PCS)). One of two partners is selected to be the timing Slave to the other. If only one partner is capable of loop timing, that partner becomes the Slave. If both partners are capable of loop timing, symmetry breaking can be used to determine which partner should become Slave.
