  The following SIO information:

  • The network indicator code of 2 (nic=2)
  • The service indicator of 3 (si=3)
  • Message priorities ranging from 1 to 3 (:pri=1&&3)

  The calling party address (CGPA) 7-100-4, with the subsystem number of 254 and the routing indicator (ri) of *, and the SCCP message type of UDTS
