B01MUTEO*?

8.113. NC -- Enable Noise Cancellation

This command sets or queries the status of the Noise Cancellation (NC) algorithm on input channels 1-4 and
T .
When the wildcard character, '*', is used to specify the channel in this command, it only affects input
channels 1-4 . To set or query the telephone input channel, T, you must specify it explicitly (e.g., 'B01NCT1'
'' '', 'B01NCT?' '' '').
This command is a channel boolean command. See
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.

8.114. NCL -- Set Noise Cancellation Attenuation

Toggle mute status of all
outputs.
Query mute status of all
outputs.
B01MUTEO*abcdefghij 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
