I've provided double ring with a regular 1A2 interrupter by installing a slave relay that tracks the 60 IPM lamp flash rate. Of course, finding a relay that has a coil for 10VAC is a bit of a stretch, but a full wave bridge connected to the coil of a 12VDC relay will work just fine. Contacts on this relay are used to interrupt the RN output, providing a precise double ring cadence, right from a stock interrupter with no modifications.
Oh, and yes... Using the 120 WPM wink rate to drive a slave relay will generate some interesting triple ring patterns too.
