Abstract:
1. An apparatus, comprising: a physical layer (PHY) transceiver configured to communicate over a single twisted pair channel; and a setup logic configured to control the PHY transceiver to initiate an auto-negotiation sequence over the single twisted pair channel with a remote device upon detecting a transmission from the remote device on the single twisted pair channel, wherein the auto-negotiation sequence includes an exchange of parameters with the remote device using a half-duplex mode to communicate on the single twisted pair channel, wherein the PHY transceiver is configured to communicate with the remote device in the half-duplex mode by asynchronously sending and receiving communications for the auto-negotiation sequence over the single twisted pair channel, and wherein the PHY transceiver communicates asynchronously by sending and receiving communications of the auto-negotiation sequence at different times on the single twisted pair channel; and a duplex logic configured to control the PHY transceiver to switch from the half-duplex mode to a dual-duplex mode to establish a connection with the remote device over the single twisted pair channel based, at least in part, on the parameters from the auto-negotiation sequence, wherein the PHY transceiver is configured to simultaneously transmit and receive communications on the single twisted pair channel when switched to the dual-duplex mode, wherein the auto-negotiation sequence consists of communications provided asynchronously back-and-forth over the same single twisted pair channel, wherein the setup logic is configured to use the auto-negotiation sequence to initially establish communications with the remote device upon being initialized, and wherein the single twisted pair channel is established in a cable including only one twisted pair of wires.
