Alternately, can a 2 - wire ring coil from a rotary dial 500 phone be used? Does it affect the REN adversely? Any help is greatly appreciated. Ciao.

The ringer capacitor is A and K on the network. One side of the ringer goes to L1, the other side of the ringer goes to K, and a jumper wire from A to L2 will complete the circuit. | | | | Forums93 Topics94,340 Posts639,394 Members49,444 | | Most Online5,661
