The table below shows the PPL Event Indications for QSIG/PSS1.

PPL Event Indication | 0x0001

This usually happens when the host sends a L4 SEGMENT PPL Event Request, without first sending a call processing message containing a Segment ICB.
PPL Event Indication | 0x0002
Name | Segmentation Failure - Wrong or Unexpected Segmented Message
Description | The CSP sends this PPL Event Indication to the host when a failure occurs in the segmentation procedure due to an invalid Segmented Message or Segmented Message with a different Call Reference IE.
