Each side chooses its Sequence Number (sequence control parameter and
ultimately SLS value) independently.  It is unlikely that it is in any
way related to the value chosen by the peer.  (The SCCP-User does not
normally have access to this value in receive N-UNITDATA-Indication
primitives, but may set Sequence Control in N-UNITDATA-Request primitives,
cf. Q.711.)
