Two-way data communication over dual single-pair ethernet links

A two-way data communication method of a two-way data communication system, the two-way data communication method comprising:

• receiving source data, wherein a first packet management module of a first communicating device, configured to implement a single pair Ethernet protocol, respectively a second packet management module of a second communicating device, configured to implement a single pair Ethernet protocol, receives a source packet comprising N bits to be transmitted to the second communicating device, respectively to the first communicating device;
• generating intermediate frames, wherein the first packet management module of the first communicating device, respectively the second packet management module of the second communicating device, generates:
• a first intermediate frame comprising M data bits as a function of N bits of the source packet to be transmitted, and
• a second intermediate frame comprising P data bits as a function of the N bits of the source packet to be transmitted;
• transmitting intermediate frames, wherein:
• a first physical link management module of the first communicating device, respectively of the second communicating device, transmits the first intermediate frame on a first connector-module link, and
• a second physical link management module of the first communicating device, respectively of the second communicating device, transmits the second intermediate frame on a second connector-module link, the first physical link management module and the second physical link management module being linked by separate single pair link;
• receiving intermediate frames, wherein:
• the first physical link management module of the second communicating device, respectively of the first communicating device, receives the first intermediate frame on a first connector-module link, and
• the second physical link management module of the second communicating device, respectively of the first communicating device, receives the second intermediate frame on a second connector-module link;
• transmitting intermediate frames, wherein the first intermediate frame and the second intermediate frame are transmitted to the second packet management module of the second communicating device, respectively to the first packet management module of the first communicating device;
• and
• reconstituting source data, in which the second packet management module of the second communicating device, respectively the first packet management module of the first communicating device, reconstitutes the N data bits of the source packet as a function of the M data bits of the first intermediate frame and of the P data bits of the second intermediate frame.
