REPEATER FOR SUPPORTING MULTI PROTOCOL AND CONTROL METHOD OF PROTOCOL CONVERTING IN IT

摘要

Disclosed are an Ethemet-IEEE 1394 repeater apparatus as a network transmission equipment wherein a protocol conversion can be performed to operate a single repeater combining therein an Ethernet repeater function, and a method for protocol conversion thereof. The repeater apparatus, for supporting a plurality of protocol including a first protocol and a second protocol which use the same transmission media, includes an input interface for inputting therein data through an input transmission media; a first protocol physical element for performing a modulation/demodulation process of a first protocol data to transmit the data; a second protocol physical element for performing a modulation/demodulation process of a second protocol data to transmit the data; an output interface for outputting the data through an output transmission media; a first switch for switching the data input to the input interface to one of the first protocol physical element and the second protocol physical element; a second switch, tuned with the first switch, for switching an output path to one of the first protocol physical element and the second protocol physical element, the output path being connected to the output interface; and a control unit for receiving a protocol information of data sent from one of the first protocol physical element and the second protocol physical element to control the first switch and the second switch based on the received protocol information, the one being selectively connected based on the current switching condition of the physical element.
