AT&T's System 25 does propagate the loop current interrupt signal
toward its tip/ring stations when a trunk releases the PBX.  The
propagation is delayed by a few seconds.

Systems 75 and 85 also propagate the loop interrupt, but it is delayed
by up to 60 seconds.

Can anybody answer John's questions for Merlin, Spirit, and Partner?
