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.

Note 2:

The rise time is the time from 10% of final value till the tone amplitude has reached

90% of its final value.

Note 3:

Relative to high group.

Note 4:

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.

Note 5:

This does not include the frequency deviation of the ceramic resonator.
