Step 22:TCAPCSL (transaction-capable applying portion Component Sub-Layer) receives TR_BEGING_IND (the transaction sub-layer beginning of conversation indication) message of TCAPTSL.

Step 23:TCAPCSL (transaction-capable applying portion Component Sub-Layer) decodes to the TR_BEGING_IND message of receiving, look for the module No. of MAP (MAP), then decoded results, may be that TC_BEGING_IND (Component Sub-Layer beginning of conversation indication) and TC_INVOKE_IND (calling the composition indication) send to module 2MAP if not this module (being assumed to module 2).

Step 24: finish after the dialogue alternately the MAP inside of module 2, and the MAP of module 2 receives the response for the TCAPCSL transmission of module 1, may be TC_L_RESULT_REQ (composition request as a result) and TC_END_REQ (request of Component Sub-Layer end-of-dialogue) message.

Step 25: the TCAPCSL of module 1 receives that the message of module 2 sends TR_END_REQ (request of transaction sub-layer end-of-dialogue) message to the TCAPTSL layer afterwards.

Step 26:TCAPTSL sends N_UNITDATA_REQ (cell data request) message for SCCP (SCCP Signalling Connection Control Part) after receiving TR_END_REQ message.
