This command sets or queries the status of the line echo canceller (LEC). 

This command is a boolean command. See 

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.
