### 7.3.2 A-ABORT Service Procedure

7.3.2.1 When the A-ABORT service is used, the association shall be released abnormally and simultaneous with the abnormal release of the underlying connection.

7.3.2.2 A UL service-user that desires to release the association abnormally shall issue the A-ABORT request primitive. This requestor shall not issue any further primitives for the association.

7.3.2.3 The UL service-provider shall issue an A-ABORT indication primitive to the acceptor. The UL service-provider shall assign the value of "UL service-user" for the Abort Source parameter. The association and the underlying connection have been released.

7.3.2.4 The UL service-provider (ACSE related functions) may itself cause the abnormal release of the association because of internal errors. In this case, the UL service-provider shall issue A-ABORT indication primitives to acceptors in both AEs. The UL service-provider shall assign the value of "UL service-provider" to the Abort Source parameter. The user information parameter shall not be used.
