D.4.2.1.2.2 Number of Associations​

Table D.4.2-3. Number of Associations as a SCP for ECHO-SCP​

ECHO-SCP will only allow a single outstanding operation on an Association. Therefore, ECHO-SCP will not perform asynchronous​ operations window negotiation.​

D.4.2.1.3 Association Initiation Policy​

ECHO-SCP does not initiate associations.​

D.4.2.1.4 Association Acceptance Policy​

When ECHO-SCP accepts an association, it will respond to echo requests. If the Called AE Title does not match the pre-configured​ AE Title shared by all the SCPs of the application, the association will be rejected.​

D.4.2.1.4.1.3 SOP Specific Conformance​

D.4.2.1.4.1.3.1 SOP Specific Conformance to Verification SOP Class​

ECHO-SCP provides standard conformance to the Verification Service Class.​

D.4.2.1.4.1.3.2 Presentation Context Acceptance Criterion​

ECHO-SCP will always accept any Presentation Context for the supported SOP Classes with the supported Transfer Syntaxes. More​ than one proposed Presentation Context will be accepted for the same Abstract Syntax if the Transfer Syntax is supported, whether​ or not it is the same as another Presentation Context.​

D.4.2.1.4.1.3.3 Transfer Syntax Selection Policies​

ECHO-SCP prefers explicit Transfer Syntaxes. If offered a choice of Transfer Syntaxes in a Presentation Context, it will apply the​ following priority to the choice of Transfer Syntax:​

a.​first encountered explicit Transfer Syntax,​

b.​default Transfer Syntax.​

ECHO-SCP will accept duplicate Presentation Contexts, that is, if it is offered multiple Presentation Contexts, each of which offers​ acceptable Transfer Syntaxes, it will accept all Presentation Contexts, applying the same priority for selecting a Transfer Syntax for​ each.​

D.4.2.2 STORAGE-SCP​

D.4.2.2.1 SOP Classes​

STORAGE-SCP provide Standard Conformance to the following SOP Class(es) :​

D.4.2.2.2 Association Policies​

D.4.2.2.2.1 General​

STORAGE-SCP accepts but never initiates associations.​

Table D.4.2-7. Maximum PDU Size Received as a SCP for STORAGE-SCP​

Table D.4.2-8. Number of Associations as a SCP for STORAGE-SCP​

STORAGE-SCP will only allow a single outstanding operation on an Association. Therefore, STORAGE-SCP will not perform asyn-​ chronous operations window negotiation.​

D.4.2.2.3 Association Initiation Policy​

STORAGE-SCP does not initiate associations.​

D.4.2.2.4 Association Acceptance Policy​

When STORAGE-SCP accepts an association, it will respond to storage requests. If the Called AE Title does not match the pre-​ configured AE Title shared by all the SCPs of the application, the association will be rejected.​

D.4.2.2.4.1.2.1 Extended Negotiation​

No extended negotiation is performed, though STORAGE-SCP:​

•​is a Level 2 Storage SCP (Full - does not discard any data elements)​

•​does not support digital signatures​

•​does not coerce any received data elements​

D.4.2.2.4.1.3 SOP Specific Conformance​

D.4.2.2.4.1.3.1 SOP Specific Conformance to Storage SOP Classes​

STORAGE-SCP provides standard conformance to the Storage Service Class.​

When displaying an image in the viewing application, the newest Grayscale Softcopy Presentation State containing references to the​ image will be automatically applied and the GSPS Presentation Label and Presentation description will be displayed. The user has​ the option to select any other Presentation States that also references the image. If no Presentation State references the image then​ no Presentation State will be applied by default.​

The Mask Subtraction transformation is not supported by this implementation. It is not possible display Presentation States containing​

the Mask Subtraction Sequence (0028,6100).​

All of the Image Storage SOP Classes listed in Table D.4.2-6 are supported as references from instances of the Grayscale Softcopy​ Presentation State Storage SOP Class.​

D.4.2.2.4.1.3.2 Presentation Context Acceptance Criterion​

STORAGE-SCP will always accept any Presentation Context for the supported SOP Classes with the supported Transfer Syntaxes.​ More than one proposed Presentation Context will be accepted for the same Abstract Syntax if the Transfer Syntax is supported,​ whether or not it is the same as another Presentation Context.​

D.4.2.2.4.1.3.4 Response Status​

STORAGE-SCP will behave as described in the Table below when generating the C-STORE response command message.​
