Step 3
Specify (in dB) the amount of
gain to be inserted at the
receiver side of the interface.
Step 4 Specify (in dB) the amount of
attenuation at the transmit side
of the interface.
Step 5
Enable echo-cancellation of
voice that is sent out of the
interface and received back on
the same interface.
Step 6
Adjust the size (in
milliseconds) of the
echo-cancel.
Step 7 Enable nonlinear processing,
which shuts off any signal if no

(Nonlinear processing is used
with echo-cancellation.)
Step 8
Specify the number of seconds
the system will wait for the

Step 11 If the voice-port dial type is
DTMF, configure the DTMF
inter-digit signal duration.
