摘要： In a 100BASE-T4 protocol network, the "carrier.sub.-- status" signal associated with an incoming packet on a PMA of a given port of a Clause 27 repeater is obviated and a direct connection between PMAs and a Clause 27 repeater in the network is eliminated by transmitting synthetic preamble signals over the PMA-Repeater Data Interface to the Clause 27 repeater corresponding to the given port at an early time prior to the time that the actual preamble information of the packet is transmitted over that data interface. Receipt of the synthetic preamble signals causes the repeater to awaken and to repeat the synthetic preamble signals to other ports of the repeater. In turn, the other ports become quiet in anticipation of data to be repeated from the given port to the other ports of the repeater.

摘要： In accordance with one embodiment of the present invention, a signal detect circuit may analyze an input signal before passing it on to a receiver. The analysis may be done outside of the data path to avoid affecting the data path speed or adding distortion or jitter. The positive and negative thresholds of the data may be checked to see if the numbers of positive and negative crossings are comparable. Random and bursty noise can be detected since such noise normally does not have comparable positive and negative crossings.
