These tones are programmable as a single or dual frequency with programmable levels
and is applied to all lines. With a selection of Single Tone the system will only generate
the first tone. With a selection of Tone 1 + Tone 2 the system will generate both tones
with the specified frequencies and amplitudes. Purchase of the TLE-INTL Software
Module adds the selection of Tone 1 x Tone 2. The system will generate Tone 1
modulation by Tone 2. In this implementation only the fundamental and upper side tone
are generated, both at the amplitude programmed for Tone 1.
Frequency range may be set from 10 Hz to 2000 Hz in 1 Hz increments.
Signal level may be set from -6 dBm to -60 dBm in 1 dB increments.
On duration may be set from 0 Seconds to 10.000 Seconds in 5 mS increments.
Off duration may be set from 0 Seconds to 10.000 Seconds in 5 mS increments.
