Abstract
A physical layer (PHY) device which can operate as a conventional PHY or as a repeater in a communication system. The PHY repeater supports four optional modes which may be enabled by programming control register bits with a microcontroller. These optional modes are: pass all symbols, enable noise filter, pass violation symbols and pass line states. When the pass all symbols, pass violation symbols and pass line states modes are enabled, the PHY device operates as a "transparent" repeater. The repeater allows errors in a data stream to be encoded and repeated without filtering to a downstream station. The repeater also allows line states to be repeated without station management software. A single repeater may be used to couple two stations or multiple repeaters may be connected to form multi-port repeater boxes which can be connected to facilitate more reliable connections between stations.
