摘要： One embodiment monitors a line-side electrical current provided by a power sourcing equipment (PSE) port to a powered device (PD), the PSE port having a power-isolation transformer with a primary coil on an isolated side and a secondary coil on a line side. A switching signal having a switching period and a duty cycle is applied to the primary coil of the power-isolation transformer. A value is determined for an electrical current on the isolated side of the power-isolation transformer, conversion is performed between a line-side electrical current value Iout and a corresponding isolated-side peak-current value Ipeak, and the line-side electrical current is indirectly monitored based on the determined isolated-side current value.

摘要： In one embodiment, the invention is an apparatus (e.g., an Ethernet switch) having an isolated side and a line side. A line-side connector is connectable to a cable. An isolated-side physical-layer module (1) is electrically coupled to the connector via a signal-isolation transformer and (2) processes signals transmitted over the cable. A line-side power conditioning module (1) is electrically coupled to an isolated-side power switcher via a power-isolation transformer that converts an AC power signal received from the power switcher into a transformed AC power signal and (2) converts the transformed AC power signal into a cable power signal to be supplied via the connector to the cable in order to power a cable-powered device connected to the cable. An isolated-side control module performs a detection function in which the control module determines whether or not a cable-powered device is connected to the cable.

摘要： The apparatus and method herein splits the function of a digital subscriber line (DSL) modem data pump between a digital signal processor (DSP 106) and a general purpose host central processing unit (CPU 102). The DSP (106) handles all front end data pump processing such as interface to an analog front end (108 and 110), FFT processing, FEQ processing, QAM decoding, and bit formatting. The host CPU (102) handles all back end data pump processing such as DMT tone deordering, data deinterleaving, error detection and correcting, bit descrambling, CRC processing, and the like. In order to enable the DSP (106) and the CPU (102) to communicate with each other effectively, buffers (132) under the control of specialized buffer management methodology (FIG. 4) are used.
