AC Electrical Characteristics
(AC electrical characteristics supersede the recommended operating conditions unless otherwise stated.)
Dual Tone Alert Signal Detection
Notes:
a. dBm = decibels with a reference power of 1 mW into 600 ohms, 0 dBm = 0.7746 Vrms.
b. Twist = 20 log (F
1: The range within which tones are accepted.
2: The range outside of which tones are rejected.
3: These characteristics are for V
4: Both tones have the same amplitude. Both tones are at the nominal frequencies.
5: Band limited random noise 300 3400 Hz. Present only when the tone is present.
