2.14.1.1 Error Handling during Reassembly

The reassembly errors must be handled as follows:

• When a reassembly procedure fails and alwMsgDuringRsmblyErr in the sccpoptions MO is True, then all the received segmented MSUs of the message are passed for further processing.
• When a reassembly procedure fails and alwMsgDuringRsmblyErr in the sccpoptions MO is False:
  • If return on Error option is set in the XUDT Message received, then only one XUDT with data = first segment data received and the XUDTS is sent to the originator.
  • If return on Error option is not set in the XUDT Message received, then the message is discarded.
