This notification is sent at the completion of a CMTS channel override operation if cdxCmtsCmChOverTrapOnCompletion is true in the original entry. Once a channel override operation has been activated, it cannot be stopped. That is, it will run until either the CMTS has generated downstream frequency and/or upstream channel override fields in the RNG-RSP message sent to a cable modem or cdxCmtsCmChOverTimeExpiration time expired. In either case, the operation is completed. State in the cdxCmtsCmChOverState object will tell in which condition the operation is completed.
