I am trying to build a box for my five line key system phone. I want it to flash the lights and do automatic hold. Does anyone have the light flashing cadences? (frequency and duty cycle). The system I was going to time has been dismantled and replaced with Panasonic phones with LEDs so you can't tell which line is ringing...
