hate to say it but what is pictured is not a smart jack, it is as you say a
glorified patch.
a *TRUE* smart jack DOES have the tiny bit of circuitry necess'y to cause
it to loop the line back when nothing is connected to it, some can do it
via line signaling as well.
in some telco territory what they call a smart jack is, most certainly, NOT.
as always, YMMV, SBC/PacBell in SFO area usually does use a true smart
jack, but not always. out of a number of t-1s installed for both voice and
data while working at 2 Connecticut i was about 80/20 in favor of smart
jacks.
