Disclosed are embodiments that provide digital data communication between a single-pair Ethernet and a multi-pair Ethernet. Some embodiments include a single-pair Ethernet interface that is configured to operate in at least two modes. In a first mode, the single-pair Ethernet interface operates in a conventional manner. In a second mode, alternate pin configurations are employed to provide a low-cost interoperability between a single-pair Ethernet interface and a multi-pair Ethernet interface. For example, in the second mode, the single-pair Ethernet receives, via a first receive data pin, from a first transmit data pin of the multi-pair Ethernet interface, a data signal, and receives, via a second receive data pin, from a second transmit data pin of the multi-pair Ethernet interface, a second data signal.
