Description

Technical Field

[0001] The present invention relates to an Internet port interface device, and more particularly to an integrated Internet port interface device that simultaneously transmits optical signals and electrical signals.

Background Art

[0002] Generally, Ethernet switches provide various physical layer ports to accommodate different usage scenarios. For example, RJ45 ports are used for short-distance, indoor connections, and fiber optic ports are used for long-distance, indoor or outdoor connections, or in environments where high levels of interference occur in the power system. Combo ports can provide the functions of the above two types of ports simultaneously. One combo port corresponds to both one port interface on the device panel and one fiber optic port interface, but there is only one port inside the device. Therefore, it is possible to accommodate different types of port interfaces without increasing the number of port interfaces on the switch.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, conventionally, combo ports have had to rely on the processing of components with two types of port interfaces for optical signals and electrical signals from physical layer components by Ethernet switch chip companies for system companies. Such specifications are not only inconvenient but also very expensive. Therefore, there is a need for a combo port interface that does not require separate combined design for physical layer optical signal communication interfaces and electrical signal communication interfaces.

Means for Solving the Problems

[0004] The integrated port interface device according to an embodiment of the present invention includes a 1P2T switch with its first end coupled to the media access control unit of a switch chip, a first transceiver coupled to the second end of the 1P2T switch, and a second transceiver coupled to the third end of the 1P2T switch. The central processing unit of the switch chip switches the 1P2T switch based on the state of the first transceiver to couple the media access control unit to the first transceiver or the second transceiver.

[0005] In one embodiment, the switch chip is an Ethernet switch chip.

[0006] In one embodiment, the first transceiver is a transceiver with an RJ45 type connection port.

[0007] In one embodiment, the second transceiver is an optical signal transceiver.

[0008] In one embodiment, the state of the first transceiver indicates whether a transmission line is coupled to the first transceiver.

[0009] In one embodiment, when the transmission line is coupled to the first transceiver, the central processing unit switches the 1P2T switch to couple the media access control unit to the first transceiver.

[0010] In one embodiment, when the transmission line is not coupled to the first transceiver, the central processing unit switches the 1P2T switch to couple the media access control unit to the second transceiver.

[0011] In one embodiment, the transmission line is a twisted pair line.

[0012] In one embodiment, it further includes a transformer coupled to the first transceiver and a signal terminal coupled to the transformer.

[0013] In one embodiment, the signal terminal is an RJ45 type connection port.

Advantages of the Invention

[0014] Therefore, according to the technical content of the present invention, in the integrated port interface device, a 1P2T switch is provided between the media access control unit and the physical interface layer, and the central processing unit in the switch chip performs switching based on the connection state of the external transmission line, and transfers the input / output signal sent from the switch chip to the corresponding transmission interface of the physical layer for transmission. Thus, when the central processing unit detects that a transmission line is connected to the transmission interface of the electrical signal, it switches the 1P2T switch to connect to the transmission interface of the electrical signal. When the central processing unit detects that no transmission line is connected to the transmission interface of the electrical signal, it switches the 1P2T switch to connect to the transmission interface of the optical signal. Therefore, the integrated port interface device according to the present invention can solve the transmission problems of the input / output signals of two types of Internet, namely optical and electrical, and thus it is possible to transfer two types of signals, optical and electrical, through different transmission interfaces.

[0022] Conventionally, the combo port of Ethernet has to rely on the component processed by the enterprise of Ethernet switch chips to provide two types of port interfaces, optical signals and electrical signals, from the physical layer components for system enterprises. For system enterprises, it was not only inconvenient but also very expensive, so they were greatly affected by the enterprise of switch chips. Therefore, the present invention provides an integrated port interface device in which a 1P2T switch is provided between the Media Access Controller (MAC) and the physical interface layer, and the central processing unit in the switch chip performs switching based on the connection state of the external transmission line, and transfers the input / output signals sent from the switch chip to the corresponding transmission interface of the physical layer for transfer. This eliminates the need to rely on the components of specific port interfaces provided by the enterprise of Ethernet switch chips, thus reducing the construction cost.

Embodiments for Carrying Out the Invention

[0023] Figure 1 is a schematic diagram of an integrated port interface device based on a specific embodiment of the present invention. The integrated port interface device 100 includes a 1P2T switch 120, a first transceiver 130 in the physical layer, a transformer 140, a signal terminal 150, and a second transceiver 160 in the physical layer. The 1P2T switch 120 is an analog switch, and the first end 121 of the 1P2T switch 120 is coupled to the media access control unit 111 of the Ethernet switch chip 110. The first transceiver 130 is coupled to the second end 122 of the 1P2T switch 120, the transformer 140 is coupled to the first transceiver 130, and the signal terminal 150 is coupled to the transformer 140. The second transceiver 160 is coupled to the third end 123 of the 1P2T switch 120.

[0024] In one embodiment, the central processing unit 112 of the switch chip 110 switches the 1P2T switch 120 based on the state of the first transceiver 130, and switches the media access control unit 111 of the switch chip 110, so as to couple it to the first transceiver 130 of the physical layer or the second transceiver 160 of the physical layer. In one embodiment, the first transceiver 130 is a transceiver with an RJ45 type connection port for twisted pair lines, and the signal terminal 150 is an RJ45 type connection port. The first transceiver 130 is used to convert the input / output signal sent from the media access control unit 111 into an electrical signal suitable for transmission on the twisted pair line, and transfer it to the signal terminal 150. The second transceiver 160 is an optical signal transceiver, and the second transceiver 160 is used to convert the input / output signal sent from the media access control unit 111 into an optoelectrical signal suitable for transmission on the optical fiber. Therefore, when a transmission line such as a twisted pair line is externally connected to the first transceiver 130, for example, the central processing unit 112 switches the 1P2T switch 120 to couple the media access control unit 111 to the first transceiver 130, and transfers signals through the twisted pair line. When the transmission line is not externally connected to the first transceiver 130, the central processing unit 112 switches the 1P2T switch 120 to switch the media access control unit 111 and couple it to the second transceiver 160, and transfers signals through the optical fiber. The transformer 140 is provided between the signal terminal 150 and the first transceiver 130, and mainly plays roles such as combined transmission of Ethernet packet signals, impedance matching, waveform restoration, suppression of signal noise, and high voltage insulation.

[0025] In one embodiment, an Ethernet switch chip 110 provides an Internet input / output signal to a 1P2T switch 120 via a media access control unit 111. A central processing unit 112 actively accesses a first transceiver 130 to check whether a transmission line such as a twisted pair is coupled to the first transceiver 130. When the central processing unit 112 confirms that a transmission line such as a twisted pair is externally connected to the first transceiver 130, it switches the 1P2T switch 120 to transfer the Internet input / output signal to the first transceiver 130. After separation via a transformer 140, it provides the required electrical signal to a signal terminal 150, and transfers the input / output signal via a twisted pair to communicate with the outside. On the other hand, when the central processing unit 112 confirms that the first transceiver 130 is not coupled to a transmission line, it transfers the Internet input / output signal to a second transceiver 160, outputs an optical signal, and transfers the input / output signal via an optical fiber to communicate with the outside. Based on this, when neither the first transceiver 130 nor the second transceiver 160 is coupled to an external transmission line, the 1P2T switch 120 is switched to be coupled to the second transceiver 160. When both the first transceiver 130 and the second transceiver 160 are coupled to an external transmission line, the 1P2T switch 120 is switched to be coupled to the first transceiver 130. Based on this, the central processing unit 112 immediately detects a change in the transfer method of the input / output signal by sensing the coupling state of the first transceiver 130, and switches the 1P2T switch 120 based on the change in the transfer method to immediately arrange the corresponding transceiver to transfer the signal.

[0026] In one embodiment, the Ethernet switch chip 110 itself includes a plurality of media access control units 111 that can be coupled to the 1P2T switch 120 of the present invention. In other words, the present invention is not limited to being coupled to only one media access control unit 111.

[0027] FIG. 2 is a flowchart of a method for automatically switching an integrated port interface device according to a specific embodiment of the present invention. Please refer to FIGS. 1 and 2 simultaneously. The switching method 200 of the integrated port interface device first determines in step 210 whether a transmission line is coupled to the first transceiver 130. In one embodiment, the central processing unit 112 actively accesses the first transceiver 130 to confirm whether a transmission line such as a twisted pair is coupled to the first transceiver 130.

[0028] When the central processing unit 112 confirms that a transmission line is externally connected to the first transceiver 130, it switches the 1P2T switch 120 in step 212 to switch the media access control unit 111 and couple it to the first transceiver 130. In one embodiment, the central processing unit 112 transfers the Internet input / output signal to the first transceiver 130 by switching the 1P2T switch 120, separates it through the transformer 140, provides the required electrical signal to the signal terminal 150, and transfers the input / output signal through the twisted pair to communicate with the outside.

[0029] When the central processing unit 112 confirms that a transmission line is not coupled to the first transceiver 130, it switches the 1P2T switch 120 in step 213 to switch the media access control unit 111 and couple it to the second transceiver 160. In one embodiment, the central processing unit 112 transfers the Internet input / output signal to the second transceiver 160 by switching the 1P2T switch 120, outputs an optical signal, and transfers the input / output signal through the optical fiber to communicate with the outside.

[0030] As described above, in the integrated port interface device according to the present invention, a 1P2T switch is provided between a Media Access Controller (MAC) and a physical interface layer. The central processing unit in the switch chip performs switching based on the connection state of the external connection transmission line, and transfers the input / output signal sent from the switch chip to the corresponding transmission interface of the physical layer to perform the transfer. Thus, when the central processing unit detects that a transmission line is connected to the transmission interface of the electrical signal, it indicates that the externally connected transmission line is used to transmit the electrical signal, and the central processing unit switches the 1P2T switch to be connected to the transmission interface of the electrical signal. When the central processing unit detects that no transmission line is connected to the transmission interface of the electrical signal, it indicates that the externally connected transmission line is connected to the transmission interface of the electrical signal, and the central processing unit is connected to the transmission interface of the optical signal by switching the 1P2T switch. Therefore, the integrated port interface device according to the present invention can solve the transmission problems of the input / output signals of two types of the Internet, optical and electrical, and thus it is possible to transfer two types of signals, optical and electrical, through different transmission interfaces.

[0031] Each of the embodiments disclosed above is not intended to limit the present invention, and those skilled in the art can make various changes and decorations without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be based on what is defined by the scope of claims of the attached utility model registration.
