                characterized by the expiry of Timer_NO_RESPONSE.
                (This event is communicated to the layer management
                with MAA-ERROR code P.  See ITU-T Q.2110.)

             2) SSCOP Connection Initiation Failure

                This condition indicates the inability to establish
                an SSCOP connection.  This event occurs whenever the
                number of expiries of the connection control timer
                (Timer_CC) equals or exceeds the MaxCC, or upon
                receipt of a connection reject message BGREJ PDU.
                (This event is communicated to layer management with
                MAA-ERROR code O.  See ITU-T Q.2110.)

             3) SSCOP Connection Re-Establ/Resynch

                This event occurs upon receipt of a BGN PDU or
                RS PDU."
