The '''APC board''' is mandatory in the AlphaCom E20 and E26 exchanges. It controls the back plane board clocking. It also supervises board temperatures and controls the speed of the fans. This board contains circuitry for 6 audio program feed channels with galvanic isolation. Easily accessible potentiometers at the front enable sensitivity control of the audio program input. The clock can be synchronized with (phase-locked to) an external clock. The board plugs into position 26 only.
