The Ring Detector consists of a photocoupler, PC2, and its peripheral circuits. The ringing signal is
half–wave rectifier in the Ring Detector, and transferred through the nCTON signal line to the IC80 on the
FCB PC Board. The IC80 observes the signal to distinguish from signals caused by chattering.
The Off–Hook Detector (External Telephone) circuit consists of the photocoupler, PC1, and its peripheral
circuits. When PC1 detects loop current flow, it emits a Low active output signal (nHKOF) to the IC80 which
monitors it for a specified time. If the IC80 detects no change in the Low signal level, it determines that the
External Telephone is Off–Hook.
