            'missingPkt'(0) - While playing out a sequence of packets,
            at least one packet was determined to be missing based on a
            gap in the CEP sequence number.  Note: If the implementation
            supports packet reordering, detecting gaps SHOULD take
            place as they are played out, not as they arrive.  This
            provides time for misordered packets to arrive late.

            'ooRngDropped'(1) - At least one packet arrived outside the
            range of the jitter buffer.  This may be because the
            jitter buffer is full or the sequence number addresses
            a buffer outside the current jitter buffer range or
            an already occupied buffer within range.  Whether or not
            packet reordering is supported by the implementation, this
            indication MUST be supported.

Top      Up      ToC       Page 16 
            'jtrBfrUnder'(2) - The jitter buffer underflowed because
            not enough packets arrived as packets were being
            played out.

            'pktMalformed'(3) - Any error related to unexpected
            packet format (except bad header stack) or unexpected
            length.

            'lops'(4) - Loss of Packet Synchronization.

            'cepRdi'(5) - Circuit Emulation over Packet Remote Defect
            Indication.  Remote Defect Indication (RDI) is generated by
            the remote CEP de-packetizer when LOPS is detected.

            'cepAis'(6) - Remote CEP packetizer has detected an Alarm
            Indication Signal (AIS) on its incoming SONET stream.
            cepAis MUST NOT (in itself) cause a CEP PW down
            notification.

            'badHdrStack'(7) - Set when the number of
            CEP header extensions detected in incoming packets does
            not match the expected number.

            'cepNeFailure'(8) - Set when CEP-NE failure is currently
            declared.

            'cepFeFailure'(8) - Set when CEP-FE failure is currently
            declared.

            This object MUST hold the accumulated indications until the
            next SNMP write that clear the indication(s).

            Writing a non-zero value MUST fail.

            Currently, there is no hierarchy of CEP defects.

            The algorithm used to capture these indications
            is implementation specific."

            By default, all the read-create objects MUST NOT be

            pwCepCfgRowStatus from the active(1) state for

            reboot, the agent MUST ensure the integrity of those
