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