This read-only INTEGER reports inprogress, success, or failure for the last OAM ping test, with the description noting an invalid result can occur if the test can't be run at all, such as against an unacquired ComPort. An admin checks this after invoking hcxStuPingTestAction to determine whether the subscriber device is reachable at the OAM layer. For example, a failure(3) result here after pinging a customer's ComPort tells the admin the device is not responding even though it may show as physically acquired.
