Note 1:
The values are valid during automatic dialling and are minimum values during
manual dialling, i.e. the tones will continue as long as the key is depressed.
The rise time is the time from 10% of final value till the tone amplitude has reached
90% of its final value.
Relative to high group.
The FCI circuit is reset by POR and HS/DP pulled 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.
This does not include the frequency deviation of the ceramic resonator.
-37 dBm at 4.3 kHz and decreasing 12 dB/octave till 28 kHz.
