Signaling System No.7 Protocol Architecture And Sevices part 69 docx

Appendix E. ITU-T Q.931 Messages
The table in this appendix summarizes Q.931 messages and the purpose of each.
Q.931 is the layer 3 protocol of the subscriber signaling system used for ISDN and
is known as Digital Subscriber Signaling System No. 1 (DSS 1). It employs a
message set that is made for interworking with SS7's ISDN User Part (ISUP). As
such, the message set maps to the ISUP message set.
