E2143 Cmd Rej: The terminal state request was unanswered

There is a problem with the E5-OAM cards or the extended bus interface (EBI) between them. This problem is preventing the system from determining what state the specified terminal or port is in. The terminal or port attributes cannot be changed until the state of the terminal or port can be determined. This error message follows other error messages or system troubles.
