uh... The whole *point* of current loops is that they are insensitive to
distance and have better noise immunity when compared to voltage
signalling. And even 30AWG is capable of handling 20mA. :-)
The only thing that would affect the loop in your list is the telco
engineers, I'm afraid... That and craptastic sourcing equipment.
