This parameter shall be provided either by the acceptor of the A-ASSOCIATE request, by the UL service-provider (ACSE related function), or by the UL service-provider (Presentation related function). It shall indicate the result of using the A-ASSOCIATE service. It shall take one of the following symbolic values:
b) rejected (permanent);
c) rejected (transient).
Note: The rejected (permanent) implies that the association calling UL user (when returning such a result to an association request) does not need to “call later.” A permanent situation exists that prevents the association establishment (e.g. remote DICOM Application Name unknown).
