Abstract
Abstract An Ethernet having an automatic detecting function of data transfer rate to efficiently manage the Ethernet, comprising a medium access controller for controlling Ethernet transfer protocol; a detector for automatically detecting a rate of data transfer received from a communication medium and driving said medium access controller to automatically control a transceiving path according to data transfer rate; an encoder/decoder enabled according to a transmitting/receiving mode selection by said medium access controller for encoding/decoding data to be suitable for the transfer protocol during data transceiving; and a data transceiver enabled according to a transmitting/receiving mode selection by said medium access controller and for transmitting and/or receiving the data to and/or from the communication medium during the data transceiving.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
86 words
An Ethernet having a rate of transfer of data detecting function comprising: a medium access controller for controlling a transfer protocol between a host and a communication medium; a detector for detecting a rate of transfer of data received from the communication medium and enabling said medium access controller to control said transfer protocol according to the data transfer rate; an encoder/decoder for encoding/decoding said data according to said transfer protocol; and a data transceiver for transmitting or receiving said data according to said transfer protocol.
Claim 2
Dependent Claim
86 words
An Ethernet having a rate of transfer of data detecting function comprising: a medium access controller for controlling a transfer protocol between a host and a communication medium; a detector for detecting a rate of transfer of data received from the communication medium and enabling said medium access controller to control said transfer protocol according to the data transfer rate; an encoder/decoder for encoding/decoding said data according to said transfer protocol; and a data transceiver for transmitting or receiving said data according to said transfer protocol.
Claim 3
Dependent Claim
54 words
An Ethernet as recited in claim 1, wherein said detector comprises a plurality of D flip-flops and a logic gate and outputs a rate detection output signal according to a determination of whether there is received data from said data transceiver and a data transfer rate detection input signal received from said communication medium.
Claim 4
Independent Claim
92 words
A method of selecting the data transfer protocol of an Ethernet comprising the steps of: detecting a data receiving rate signal of data transferred from a communication medium to a data transceiver; processing the detected data receiving rate signal with a CRS signal from a receiving block of said data transceiver for generating a rate detection signal and transmitting the rate detection signal to a medium access controller; and enabling a transfer protocol between a host and the communication medium corresponding to the rate detection signal received by the medium access controller.
Claim 5
Independent Claim
92 words
A method of selecting the data transfer protocol of an Ethernet comprising the steps of: detecting a data receiving rate signal of data transferred from a communication medium to a data transceiver; processing the detected data receiving rate signal with a CRS signal from a receiving block of said data transceiver for generating a rate detection signal and transmitting the rate detection signal to a medium access controller; and enabling a transfer protocol between a host and the communication medium corresponding to the rate detection signal received by the medium access controller.
Claim 6
Dependent Claim
37 words
A method of claim 3 wherein the enabling step comprises: selecting an encoder/decoder corresponding to a transfer protocol of the rate detection signal; and selecting a transceiver corresponding to a transfer protocol of the rate detection signal.
