Hi Guys,

I am having a weird issue on my WECO 551B KSU. Everything was working prefect after punched down the station cable and the incoming Phone CO lines. Did some tests and everything was working..

After I moved the KSU to the side to clean up the mess the weird issue started. The buzzer in the phone turned on and stayed on continuously and will not turn back off. The only time its off is when a incoming line comes in and the interrupter starts up after the call is disconnected the buzzer will turn on continuously again.

I swapped phones and line KTUs and the same issue.

I am wondering if I have a open circuit that I am not seeing or not seeing what could cause this.


Any thoughts on this?





Thanks Brian
