Sequence Control (6.2.2.2.2/Q.711)
The field is coded with the value of the sequence control parameter
associated with a group of messages and are chosen so as to ensure
proper loadsharing of message groups over SLS values while ensuring
that sequence control values within message groups have the sequence
control value coded with the same value as the initial message of the
message group.
So, pick a value that ensures proper loadsharing over SLS for your
protocol class 0 messages.
