Explanation

<CH>

CH= 1-4	Parameter to apply to the specified
	microphone channel
CH= *	Parameter to apply command to all
	microphone channels
<X>
X=0	Parameter to set the state to OFF
X=1	Parameter to set the state to ON
X=Null	Parameter to return the current state

Return Values

The command will return the updated condition (On=1, Off=0) of the echo canceller in the same format as the command.

ERLE

This command reports back the echo return loss enhancement (ERLE) for a microphone channel in dB.

[DEVICE] ERLE <CH>

Explanation

<CH>

CH= 1-4 Parameter to apply to the specified microphone channel

Return Values

The command will return the ERLE of the microphone channel in the same format as the command (#10 ERLE 1 20).
