Zenodo
The two-to-four wire hybrid circuit enables simultaneous two way communications down a single pair of wires, typically unshielded twisted pairs. This electric analog circuit is employed in the POTS ("plain old telephone system"), especially with XDSL (digital subscriber lines) for broadband communication when connecting to the Internet.
