The value of this attribute can be "off", "line", "system" or "remote". 3. Activate Activate loopbac loopback k mode on the particu particular lar E1/T1 E1/T1 interfac interface. e. Example: OSmon>
This example makes the node start listening for standardized loopback control patterns that allows the remote end to activate/deactivate loopback mode on the interface.
