high (off-hook). After a reset the FCI circuit is in a
standby state. A positive edge on FCI will start a 73
ms timer and the frequency discrimination is
initiated. Whenever a period of the ring signal is
missing, the timer is reset. When a valid ring signal
is present for 73 ms, the melody generator is
started and is directly controlled by the ring signal.
This condition will remain until a new reset.
