8.109. NC -- Enable Noise Cancellation

This command sets or queries the status of the Noise Cancellation (NC) algorithm on input channels 1
and T .
When the wildcard character, '*', is used to specify the channel in this command, it only affects input
channel 1. To set or query the telephone input channel, T, you must specify it explicitly (e.g., '' ''
'S01NCT1', '' '' 'S01NCT?').
This command is a channel boolean command. See
on this type of command.
This command is saved to non-volatile memory only as part of a preset. The state of this command
will be restored after power-up only if a preset is saved and that preset is set to be the power-on
preset.
Example Description
S01NC11 Enable NC on input channel 1 .
S01NCT0 Disable NC on input channel T.
S01NC12 Toggle NC state on input channel 1 .
S01NC1? Query NC state on input channel 1 .
S01NC*1 Enable NC on input channels 1 and T .
Disable NC on all microphone input
S01NC*0
channels (only input 1 on EF2211) .
Toggle NC state on all microphone input
S01NC*2
channels (only input 1 on EF2211) .

8.110. NCL -- Set Noise Cancellation Attenuation

This command sets or queries the attenuation level of the Noise Cancellation algorithm on input
channels 1 and T . For example, if NCL is set to 10, then the Noise Cancellation for that channel will
S01MUTEO*abcd , where each of the letters
(a, b, etc.) is either 0 or 1 depending of the
current status of the mute on the
corresponding output. If this command was
sent after the example above, then the status
message would be S01MUTEO*0110
Section 6.3 and Section 6.1
Status Message
S01NC11
S01NCT0
S01NC1x , where x is 0 or 1 depending on
the current state of NC on input channel 1 .
S01NC1x , where x is 0 or 1 depending on
the current state of NC on the input channel.
S01NC*1
S01NC*0
S01NC*x , where x is 0 or 1 depending on
the current state of NC for each of the
corresponding input.
S01NC*x , where x is 0 or 1 depending on
the current state of NC for each of the
corresponding input.
