%E - Enable/Disable Line Quality Monitor, Auto-Retrain, and Auto-Rate
Renegotiation
This command controls whether or not the modem will automatically monitor the line quality

enabled, the modem attempts to retrain for a maximum of 30 seconds.
Syntax
%E[<value>]
Defined Values
<value> A decimal number corresponding to the selected option:
0 Disable line quality monitor, auto-retrain, and autorate
renegotiation.
