- I'm trying to find a book or books or just schematics from some kind soul,
- that would enable to me to have a 2-line system (modifying a 1-line phone)
- that would have a light for the ringer (on each line), and same light
- would light (and stay lit) while that line was in use. So, I need plans
- for a 2-line HOLD circuit, and plans to light da light of a line in-use. BTW,
- the in-use light should work if an extension phone is in use also, not just
- the attached phone to said circuit.
