Hi everyone!

I just scored my second WECO 551B KSU with a 118a Frequency generator. My question is, any way to wire up a switch or a relay at the KSU to select ether ringing with the 118a Frequency generator or just buzzers for incoming calls. If so, what modifications would I have to make to the wiring at the block. I would like to have the option to switch to ether ringing or buzzing for incoming calls.

Personally I like the sound of the buzzers when a call comes in but I do not want to have the 118a Frequency generator to go to waste...... especially since it has the rare bracket...


I would appreciate any ideas and feedback.
