[mod.telecom] Advice re: building a phone ringer box

leban@UMASS-CS.CSNET (Bruce) (12/18/85)

I would appreciate any suggestions on how to build a box that can plug into
two phone lines and ring if there is a call on either one of them.  I would
like the "ringer equivalence" of the box to be as low as possible, but still
be able to produce a fairly loud (but adjustable) ring.  I also would like
to make the rings distinctive.  I may simply need two circuits for this last
requirement, but I don't even know how to build one without getting the phone
company upset.  Any suggestions?
