Appendix L. Tektronix Supporting TrafficExample L-1 shows the Message Transfer Part 2 (MTP2) exchange of Link Status Signal Units (LSSUs) that is used to bring a link into alignment, and prove it before using it for the first time or following recovery. For more information, refer to Chapter 6, "Message Transfer Part 2 (MTP2)." Example L-1.

The example shows the other protocols layers, which show how MAP is encapsulated inside Transaction Capabilities Part (TCAP); TCAP, in itself, is encapsulated inside of Signaling Connection Control Part (SCCP). SCCP, in turn, is encapsulated inside MTP. For more information, see Chapter 13, "GSM and ANSI-41 Mobile Application Part (MAP)." Example L-2.
