- Ringer equivalences are the load that the phone presents to the line on a
- ringing signal. Two 0.9 phones on the same line would present the same load
- as one 1.8 phone. I suppose it's possible that more current could damage
- a marginally designed modem if the phone plugged into it presented a high
- load, but I think this is very unlikely. The main reason that ringer
- equivalences are important is that your phone company only guarantees that
- it can support a certain value of total ringer equivalence before your phones
- will stop ringing. I forget the exact number and if it varies from company to
- company.
