Once upon a time Mark Radabaugh shaped the electrons to say...

Back to back - that will not work, because...

If there is a telco in the loop, THEY have to provide the clock. If you are
talking a T1 crossover cable, that doesn't work. You need a telco, or a
telco line simulator.

Unless you were talking the new WAN card, that can generate clock. (See,
people asked, they did it.)
