[comp.dcom.telecom] Party Line Ringer

My sister's  house is on  a party line  system that uses  some kind of
frequency selector to  select which house is  rung on the main  phone.
When she tried to put in an answering machine it answered for everyone
on her line. In the letter the phone company sent her  telling  her to
disconnect they said she could  by extra frequency  selectors for $50.
Is  there any other  sources for these? Can one   be built easily?  Is
there an ID on hers that tells what frequency it is?
