of all recorded messages must not exceed the total length for the audio memory
(8 seconds).
Attenuation
Attenuation is the loss of signal level. Attenuation values refer to the amount of
attenuation compared to the original recording.
Attenuation may be set from 0 dB to 60 dB in 1 dB increments.
Busy Tone
The Busy signal is an indication that the Called Line is off-hook and not available. Busy
Tone has several variables, including: single tone or dual tone, output level, and a
simple or complex cadence.

Busy Tone Levels and Frequencies
Busy Tones may be single or dual frequencies with individually adjustable amplitudes.
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.
For each tone, the frequency range may be set from 10 Hz to 1000 Hz in 1 Hz increments.
Output level may be set from -6 dBm to -60 dBm per tone in 1dB increments.
Busy Tone Cadence
First Cadence on time may be set from 100 mS to 2000 mS in 5 mS increments.
First Cadence off time may be set from 100 mS to 2000 mS in 5 mS increments.
