5. The calculated level must be between 0 and 10.
The attenuation levels calculated from RAM data are:
High frequency tone: – 0.5 x N680552/680554–3.5 dBm
– 0.5 x N680555 dBm
Low frequency tone: – 0.5 x (N680552/680554 + N680553) –3.5 dBm
– 0.5 x (N680555 + N680553) dBm
NOTE: N
680552
, for example, means the value stored in address 680552(H)
6. 68054A: Europe - Between Ds opening and Di opening, France - Between Ds
closing and Di opening
68054D: Europe - Between Ds closing and Di closing, France - Between Ds
opening and Di closing
7. Tone signals which frequency is lower than 1500Hz (e.g., 800Hz tone for AI
short protocol) refer to the setting at 6805B5h. Tones which frequency is higher
than 1500Hz refer to the setting at 6805B6h.
8. 68054A, 68054D, 68054E: The actual inter-digit pause (pulse dial mode) is the
sum of the period specified by the RAM addresses 68054A, 68054D, and
68054E.
