Ring trip isn't the same as line seizure, as I discovered doing my schoolboy experiments in the late 1960s. Probably only needed a few hundred μs and there was a line reversal to provide an edge for triggering one. Phone Phreaking discussions are probably verboten here so I'll leave out what my "discovery" led to.
