...I'm very familiar with RF transformers, but I'm still not sure how the system being described in this article works. --

I've read the article and I also still don't fully understand how this device works. Here's a basic schematic of a hybrid coil
[1] which helped me. The magic appears to be in opposing windings which prevent (cancel) signals from passing between transmit and receive terminals. --

Based on request above, I added the wiring diagrams for hybrid coils. But these are obsolete, replaced by resistor networks and IC circuits. The diagrams are of historical interest.

Thank you kindly, and yes, the article says it's obsolete for audio frequencies. It isn't so clear about RF hybrids, however.

I have an ITT-2500 phone on my desk with a real transformer-based hybrid in it. It's an old style of phone, but new (2009) manufacture.

Thank you for the wiring diagram! (I was about to ask what would happen if you were to use diodes instead of transformers to isolate input and output from each other. Then I
got the answer to my own question. It wouldn't work.)
