Abstract

The embodiment of the present invention relates to the technical field of Ethernet, and more specifically, relates to a transmission system and a signal transmission method of Ethernet physical layer signals, the physical layer chip of the source terminal board included in the system is used to send the physical layer signal to the switch circuit ; When the switch circuit judges that the source terminal board is connected to the system backplane through the first inter-board connector, the received physical layer signal is forwarded to the system backplane through the first inter-board connector; The physical layer signal is forwarded to the second inter-board connector, so that the physical layer information is forwarded to the physical layer chip of the terminal sub-board through the second inter-board connector; the physical layer chip of the terminal sub-board forwards the received physical layer signal to The target service sub-board is used to debug the target service sub-board according to the physical layer signal. The embodiment of the present invention can reduce the implementation cost of the Ethernet system architecture.

Description

Technical field [0001] The present invention relates to the field of Ethernet technology, and more particularly to a transmission system and signal transmission method of an Ethernet physical layer signal. Background technique [0002] In an Ethernet system architecture, in order to debug the business subboard, it is often necessary to connect a dedicated network switched chip and the corresponding module circuit in the system architecture in the MAC (MediaAccess Control) medium in the system architecture. The network switched chip and the corresponding module circuit transmit the signal of the physical layer to the business subboard that needs to be debugged, and then debugs the business slab. [0003] In practice, the dedicated network switched chip and the corresponding module circuit are expensive. Increase a dedicated network switched chip in the system architecture and the corresponding module circuit not only increase the cost of devices, but also newly added dedicated net...
