Abstract
A physical layer (PHY) device which can operate as a conventional PHY or as an intelligent repeater in a communication system. The PHY device 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. During operation as an intelligent repeater, the pass all symbols, pass violation symbols and pass line states modes are enabled. The intelligent repeater allows errors in a data stream to be encoded and repeated without filtering to a downstream station. The intelligent repeater also allows line states to be repeated without station management software. A single intelligent repeater may be used to couple two stations or multiple intelligent repeaters may be connected to form multi-port repeater boxes which can be connected to facilitate more reliable connections between stations.
