A communication system includes a first physical-layer (PHY) transceiver and a second PHY transceiver. The first PHY transceiver includes (i) a first transmitter and (ii) a first receiver including a first equalizer. The second PHY transceiver includes (i) a second transmitter and (ii) a second receiver including a second equalizer. The first PHY transceiver and the second PHY transceiver are configured to communicate with one another over a full-duplex link, including training the first equalizer on a second training signal transmitted from the second PHY transceiver, and concurrently training the second equalizer on a first training signal transmitted from the first PHY transceiver.

According to examples, a system for measuring and analyzing data to generate recommendations associated with a digital subscription line (DSL). Data associated with a DSL is measured according to one or more performance counters. The data is analyzed with respect to one or more thresholds and an anomalous performance event is determined. Also, a recommendation with respect to an performance issue associated with the anomalous performance event is provided.

Disclosed is a transmitter which includes an encoder and a transmission interface circuit. The encoder receives data bits and generates conversion bits, a number of is the conversion bits being more than a number of the data bits, based on the number of the data bits. The encoder detects a risk pattern of the conversion bits to generate detection data and converts the risk pattern into a replacement pattern based on the detection data to generate code bits, a number of is the code bits being equal to the number of the conversion bits.

A network switch includes a plurality of Ethernet ports having their respective Physical (PHY) Layers interconnected via a common interface local to the network switch. The common interface passes local information among respective PHY layers of the Ethernet ports. One or more receivers receive for a first Ethernet port, over the common interface, information indicative of alien cross talk affecting at least one second Ethernet port of the network switch. A transmission attribute controller adjusts, based on the received information indicative of alien cross talk affecting the at least one second Ethernet port of the network switch, a first data rate and/or a first transmit power level to a second data rate and/or a second transmit power level for transmitting data to a remote network device. A first transmitter transmits data via the first Ethernet port according to the second data rate and/or the second transmit power level.
