8.3.2. Telephone Line Interface

8.3.2.1. Circuit operation

  • 

On hook

Q101 is open, Q101 is connected as to cut DC loop current and cut the voice signal.

  • 

Off hook

Q101 turns on thus providing an off-hook condition (active DC current flow through the circuit) and the following signal flow is
for the DC loop current. T
