What was wrong with installing telephones in parallel. In north America we've always installed telephones in parallel and we have the REN (USA) or Load Number (Canada) to indicate the load equivalency of a device. (Network design would allow for operation of a maximum of five C-4 (electromechanical) ringers in parallel.
Granted, if you install an electronic device in parallel with an electromechanical device, the electromechanical devise tends to suck up all the current and the electronic device won't work very well. That problem is self-correcting, I can assure you. Check garbage during weekly collection day (people do not neccessarily throw away the device they should). Ciao, Vic Boersma
