Hi Everybody,

From what training I've had I understand the telephone company supplies 4-5 ringing units per line. On a 1A2 key system the number of ringing units depends on the power supply and the amount of wiring installed.

If you want to add more ringing potential without changing the power supply. What's the best approach?

Would you purchase a "ringing booster" or add a relay to the tip/ring pair at the demarc and switch an external supply?

Thanks,
Dave
