Note 1:
The values are valid during LNR dialling and are minimum values during manual dialling, i.e. the
tones will continue as long as the key is depressed.
Note 2:
The rise time is the time from 10% of final value until the tone amplitude has reached 90% of its final
value.
Note 3:
Relative to high group.
Note 4:
The FCI circuit is reset by the POR and the HS/DPB pulled high (off hook). After a reset the FCI
circuit is in a standby state. A positive edge on FCI will initiate the frequency discrimination.
Whenever a period of the ring signal is missing, the timer is reset. When a valid ring signal is
present for more than one cycle, the melody generator is started and is directly controlled by the ring
signal. This condition will remain until a new reset.
Note 5:
This does not include the frequency deviation of the ceramic resonator.
