In a 100BASE-T4 protocol network, the “carrier_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.
A physical medium attachment device for use in a 100Base-T4 protocol compatible physical layer device, said physical medium attachment device, comprising:
A method of using synthetic preamble signals to minimize data collisions between ports and to awaken said ports, which are used in a 100Base-T4 protocol repeater, comprising:
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method for causing a processor-based device to use at least one synthetic preamble signal to minimize data collisions between ports and to awaken said ports, which are used in a 100Base-T4 protocol repeater, the method comprising:
An electronic signal embodied in a carrier wave and representing sequences of instructions that, when executed by an electronic device, cause said electronic device to use at least one synthetic preamble signal to minimize data collisions between ports and to awaken said ports, which are used in a 100Base-T4 protocol repeater, by performing acts, comprising:
