Kai,I appreciate from you for suggesting a protection circuit
Jan,It is a tester as you said I am sure it can do my aim with only 0.5$,And i am sure it hasn't any danger for public telephone network,But my main question was this,Is my approach is the best? Thing that said here with other members was circuit protection! in my mind,the probability of firelight and using the device at onetime is not so much to increasing total price with circuit protection, Best Mehdi |
