Yes, Pan is right, the fact that there is no Authentication first is very weird. Is it standard that the Classmark request is done before everything else ?
Pan > Connection Confirm and Connection Request are SCCP messages, aren’t they ? They exchange CIC identification on both ends (BSC and MSC), with link number and timeslot number.
