2.2.1.2.3 Asynchronous Nature
Table 2.2-5: Asynchronous Nature as an Association Initiator for DICOM Store AE
Maximum number of outstanding asynchronous transactions 1
The DICOM Store AE allows a single outstanding operation on any association. Therefore, it does not
support asynchronous operations window negotiation, other than the default as specified by the DICOM
specification.

2.2.1.3 Association Initiation Policies
2.2.1.3.1 Activity – Send Images
2.2.1.3.1.1 Description and Sequencing of Activity
A user can select an image and request it to be sent to a destination The request is forwarded to the job
queue and then processed. An image can also be sent automatically when closing an exam.
Note:
An image can only be sent to an archiving destination if it hasn’t been archived there yet.
The DICOM Store AE is then invoked by the queue that is responsible for processing network archival tasks
for a specific destination. The DICOM Store AE will attempt to initiate a new Association in order to issue a
C-STORE request. If the job contains multiple images, then multiple C-STORE requests will be issued over
the same Association. The association will be closed when the last image (or GSPS) is sent.
If the association cannot be opened, the job is set to a retry state. If after a configurable number of retries the
job still fails, it is set to an error state (“Failed”). It can then be restarted by the user through the job control
interface. If three successive jobs to a same destination fail, the queue for that destination will be stalled. It
will retry to process the job three (3) more times. If this fails, the queue for that destination will be stalled for a
longer time, meaning that it will only retry jobs to that destination every five (5) minutes.
When the association was rejected by the device due to a configuration issue, the queue for that device will
be stalled when three (3) successive jobs experience a device failure.
If the Remote AE is configured to support Storage Commit, the DICOM Store AE will send a Storage Commit
request (N-ACTION) over a new association and will then wait for an N-EVENT-REPORT. If the N-EVENT-
REPORT does not arrive within the waiting period, the AE closes the association and assumes that a
separate association will be set up for the N-EVENT-REPORT. If this report does not arrive within a
(configurable) amount of time, the job will be marked as FAILED.
