This section explains the association operation functions used by SPPs for a communication event. An association operation function is as follows:

• dc_xat_connect - Establish an association

Association operation functions (dc_xat_~) can be used only for TP1/Server Base. For TP1/LiNK, no association operation function can be used.

Only the SPPs for a communication event can call association operation functions. The other OpenTP1 UAPs (SUP, SPP, and MHP) cannot use association operation functions.

Always specify betran in the server_type operand of the user service definition of SPPs for a communication event.
