A method of operation on an Ethernet network having multiple Ethernet links interconnected via a network device. The method includes detecting installation of a new Ethernet link in the Ethernet network utilizing the network device. A link training process is then initiated for the new Ethernet link. The link training process includes transmitting training data at a first transmit power level and first data rate to a link partner during a data transfer interval. Network feedback information is then accessed, including performance metrics associated with the multiple Ethernet links during the training data transfer interval. The first data rate and/or first transmit power level are then adjusted to an adjusted second data rate and/or second transmit power level based on the network feedback information.

Crosstalk amelioration systems and methods in a radio frequency front end (RFFE) communication system provide a host or master of an RFFE bus to monitor a weakly-driven data line in the RFFE bus while a clock line is actively providing a clock signal for trigger events at one or more slaves on the RFFE bus. If the host detects noise on the data line that looks like a sequence start condition (SSC) signal, the host further signals on the data line to negate the impact of the false SSC signal and thus avoid misinterpretation by the slaves.

A pipeline AC mitigation SSD Marker Station has a shape and land surface area footprint that are similar to conventional pipeline location markers or corrosion test stations. The SSD Marker Station includes an SSD device that connects an underground metallic pipeline to an underground grounding conductor. The SSD Marker Station further includes a disconnect switch configured to disconnect the SSD device from the pipeline and/or grounding conductor. Also included is a pair of testing ports that are in electrical communication with the SSD device. Testing of the SSD device thereby requires only operating the disconnect switch to isolate the SSD device from the pipeline and/or grounding connector and performing an electrical measurement across the testing ports. In embodiments, the SSD Marker Station meets all requirements applicable to a pipeline location marker, and can be installed in lieu of a pipeline location marker.

A vectoring controller for configuring a vectoring processor that jointly processes DMT communication signals to be transmitted over, or received from, a plurality of N subscriber lines according to a vectoring matrix. In accordance with an embodiment, the vectoring controller is configured, for given ones of a plurality of tones, to enable the given tone for direct data communication over a first set of N−Mk targeted lines out of the plurality of N subscriber lines, and to disable the given tone for direct data communication over a second disjoint set of Mk supporting lines out of the plurality of N subscriber lines, Mk denoting a non-null positive integer. The vectoring controller is further configured to configure the vectoring matrix to use an available transmit or receive power at the given tone over the second set of Mk supporting lines for further enhancement of data signal gains at the given tone over the first set of N−Mk targeted lines.
