Polycom Vortex EF2201 User Manual

This command is a boolean command. See Section 6.1 for more information on this type of command.
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved
each time it is changed. It will retain its value after power-down. Since this command writes to non-
volatile memory, there will be a delay before an acknowledgment is returned.
Example Description Status Message
T01ACKMOD1
Enable acknowledgement mode.
T01ACKMOD1
T01ACKMOD0
Disable acknowledgement mode.
T01ACKMOD0
T01ACKMOD2
Toggle acknowledgement mode.
T01ACKMODx, where x is 0 or 1 depending on the
current state of acknowledgement mode.
T01ACKMOD?
Query acknowledgement mode.
T01ACKMODx, where x is 0 or 1 depending on the
current state of acknowledgement mode.
8.3. AGC -- Enable or Disable Mic/Line Input Automatic Gain
Control
This command sets or queries the status of the Automatic Gain Control (AGC) algorithm on input
channel T (the telephone input).
This command is a channel boolean command. See
Section 6.3 and Section 6.1 for more information 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 Status Message
T01AGCT1
Enable AGC on input channel T.
T01AGCT1
T01AGCT0
Disable AGC on input channel T.
T01AGCT0
T01AGCT2
Toggle AGC state on input channel T.
T01AGCTx, where x is 0 or 1 depending on the
current state of the AGC on input channel T.
T01AGCT?
Query AGC state on input channel T.
T01AGCTx, where x is 0 or 1 depending on the
current state of the AGC on input channel T.
8.4. AGCMAX -- Set Maximum Allowed Mic/Line Input AGC
Gain
This command sets the maximum gain that the AGC can apply on input channel T (the telephone
input). For example, if AGCMAX is set to 10, then the AGC for that channel can apply a maximum of 10
dB of gain to the input signal.
This command is a channel integer command. See
Section 6.3 and Section 6.2 for more information on
this type of command. The minimum and maximum values for this command are 0 and 15,
