Volume Control
You can adjust the Speaking Volume (Transmit) on FXO port so that your voice will be clearly heard by the remote
user when the speech is established. You can also adjust the Listening Volume (Receive) on FXO port so that you
can hear clearly the remote user's voice, when the speech is established.
• Speaking Volume: The ATA211 supports programmable Speaking volume from values -6dB to +6dB in
steps of 1 dB, viz. -6, -5,-4,-3,-2,-1,0,+1,+2,+3,+4,+5,+6 (dB).
Default = 0dB.
• Listening Volume: The ATA211 supports programmable Listening volume from values -6dB to +6dB in
steps of 1 dB, viz. -6, -5,-4,-3,-2,-1,0,+1,+2,+3,+4,+5,+6 (dB).
Default = 0dB.
Echo Cancellation
Echo Cancellation is a technique that allows isolation and filtering of unwanted signals caused by echoes.
Sometimes an echo is produced while talking on phone due to which it becomes difficult to hear and understand the
speech of the remote party. Echo cancellation mechanism puts a signal on the return transmission path, which is
equal and opposite of the echo signal.
• Enable Echo Cancellation?: Select this as 'Yes' to enable Echo Cancellation or 'No' to disable it. The tail
length should be selected for programming Echo Cancellation if it is enabled. Default = Yes.
• Tail Length: Program this parameter if Echo Cancellation is enabled. Select the tail length depending on
the length of the echo to be compensated.
Valid range of tail length is 8 to 32 msec. Default = 32 msec.
