Note 1: The values are valid during automatic dialing and
are minimum values during manual dialing, 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/DPN 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.
Note 6: During temporary MF mode.
Note 7: An invalid key entry in program mode will invoke a
tone sequence with 4 tone bursts of 40 ms and
pauses between bursts of 28 ms and abort the
program mode.
Note 8: Pauses inserted within the first 5 entries of a digit
string will be automatically terminated after 2
seconds. Pauses inserted after location 5 can only
be terminated manually by pressing the PS or LNR
key.
