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 until 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 73ms 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 ≥ 73ms, 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.
