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.
