Valid values for this variable are activated and notActivated and the default is notActivated. Set this variable to 'activated' to request check v52LinkId with the LE side link id. When the checkId is finished, this value will be 'notActivated'. Setting the value to 'notActivated' has no impact. A link identification check can successfully be started only when the link is operational. This link identification procedure can be initiated from either the AN or LE side but LE has priority over AN initiated request in case of collision of requests from AN and LE, in which case, the v52LinkCheckId request will fail. It is up to the system management to initiate the link identification or not. It can be performed by the system management on a timed basis, or be applied after re-provisioning.
