Voice and Tone Parameters
The parameters in the following sections control the connection to the local phone (FXS) port on the VoIP
Subsystem. This includes control of both the Subscriber Line Interface Circuit (SLIC) and Subscriber Line
A
Subsystem. This includes control of both the Subscriber Line Interface Circuit (SLIC) and Subscriber Line
A
udio Circuit (SLAC) that together make up the FXS port.
Voice, Tone and DTMF Parameters
The following table lists parameters that control voice and tone signals, transmit and receive levels, and

Description
Default
Voice RX Gain (-20 to +10 dB)
Voice receive gain in dB
0
Voice TX Gain (-20 to +10 dB)
Voice transmit gain in dB
0
Tone Gain (-20 to +10 dB)
Tone signal gain in dB (applied to locally
generated tones such as call paging
tones).
generated tones such as call paging
tones).
0
Tone Max (-20 to 0 dBm)
When two tones of equal amplitude are
added together, the signal level is 3dB
higher than the individual components.
When four tones of equal amplitude are
added together, the signal level is 6dB
higher than the individual components.
This limit prevents inadvertent saturation
and user hearing damage.
