Summary:

This characteristic is a variable length structure containing a Flags field, a Pulse Flags field, and based on the contents of the Flags field, may contain a Pulse Quantifier field and a Pulse-Pulse Interval field.The maximum length of this structure if all Flags are set is 8 octets.

Note:

The fields in the above table, reading from top to bottom, are shown in the order of LSO to MSO, where LSO = Least Significant Octet and MSO = Most Significant Octet. Where fields with the format ‘nibble’ have been defined in the above table, the fields are shown in the order of Least Significant Nibble first, when reading the table from top to bottom. Where the characteristic definition contains two adjacent nibbles and the service specification has defined that that pair of nibbles comprise a single octet, the Least Significant Nibble means the four bits numbered 0, 1, 2 and 3 of the octet and the Most Significant Nibble means the four bits numbered 4, 5, 6 and 7 of that octet.
