      | A table that contains the latest occurrence of

        - Destination Address Field Format Error,
        The following pertains to the 60 least significant
        bits of the 64 bit address field.  The 60 bits
        contained in the address subfield can be used to
        represent addresses up to 15 decimal digits.  Each
        decimal digit shall be encoded into four bits
        using Binary Coded Decimal (BCD), with the most
        significant digit occurring left-most.  If not all
        15 digits are required, then the remainder of this
        field shall be padded on the right with bits set
        to one.  An error is considered to have occurred:
        a).  if the first four bits of the address
        subfield are not BCD, OR b).  if the first four
        bits of the address subfield are populated with
        the country code value 0001, AND the 40 bits which
        follow are not Binary Coded Decimal (BCD) encoded
        values of the 10 digit addresses, OR the remaining
        16 least significant bits are not populated with
        1's, OR c).  if the address subfield is not
        correct according to another numbering plan which
        is dependent upon the carrier assigning the
        numbers and offering SMDS.
        - Source Address Field Format Error,
        The description of this parameter is the same as
        the description of the Destination Address Field
        Format Error.
        - Invalid BAsize Field Value,
        An error is considered to have occurred when the
        BAsize field of an SIP L3PDU contains a value less
        that 32, greater than 9220 octets without the
        CRC32 field present, greater than 9224 octets with
        the CRC32 field present, or not equal to a
        multiple of 4 octets,
        - Invalid Header Extension Length Field Value,
        An error is considered to have occurred when the
        Header Extension Length field value is not equal
        3.
        - Invalid Header Extension - Element Length,
        An error is considered to have occurred when the
        Header Extension - Element Length is greater than
        12.
        - Invalid Header Extension - Version Element
        Position, Length, or Value,
        An error is considered to have occurred when a
        Version element with Length=3, Type=0, and Value=1
        does not appear first within the Header Extension,
        or an element Type=0 appears somewhere other than
        within the first three octets in the Header
        Extension.
        - Invalid Header Extension - Carrier Selection
        Element Position, Length, Value or Format,
        An error is considered to have occurred when a
        Carrier Selection element does not appear second
        within the Header Extension, if the Element Type
        does not equal 1, the Element Length does not
        equal 4, 6, or 8, the Element Value field is not
        four BCD encoded decimal digits used in specifying
        the Carrier Identification Code (CIC), or the
        identified CIC code is invalid.
        - Header Extension PAD Error
        An error is considered to have occurred when the
        Header Extension PAD is 9 octets in length, or if
        the Header Extension PAD is greater than zero
        octets in length and the Header Extension PAD does
        not follow all Header Extension elements or does
        not begin with at least one octet of all zeros.
        - BEtag Mismatch Error,
        An error is considered to have occurred when the
        Beginning-End Tags in the SIP L3PDU header and
        trailer are not equal.
        - BAsize Field not equal to Length Field Error,
        An error is considered to have occurred when the
        value of the BAsize Field does not equal the value
        of the Length Field.
        - Incorrect Length Error, and
        An error is considered to have occurred when the
        the Length field value is not equal to the portion
        of the SIP L3PDU which extends from the
        Destination Address field up to and including the
        CRC32 field (if present) or up to and including
        the PAD field (if the CRC32 field is not present).
        As an optional check, an error is considered to
        have occurred when the length of a partially
        received SIP L3PDU exceeds the BAsize value.
        - MRI Timeout Error.
        An error is considered to have occurred when the
        elapsed time between receipt of BOM and
        corresponding EOM exceeds the value of the MRI
        (Message Receive Interval) for a particular
        transport signal format.
        An entry is indexed by interface number and error
        type, and contains Source Address, Destination
        Address and a timestamp. All these errors are
        counted in the sipL3Errors counter.  When
        sipL3PDUErrorTimeStamp is equal to zero, the
        SipL3PDUErrorEntry does not contain any valid
        information. |
