Can somebody point me toward a ring-detection IC?  I've checked my
recent Harris, Dallas, and SS databooks, and I find lots of Call
Progress Detectors, but what I want is ring-detection.  Preferably for
more that one line per package (I'm thinking 10-20 lines into the
device, maybe even 25 and hook up directly to a 21X termination.)

Thanks!  (P.S.  Do the ICLID ICs coming out these days have a ring
indication line, or do they assume you've got a separate ring-detect
circuit?)
