pynetdicom.pdu_primitives.SCP_SCU_RoleSelectionNegotiation¶
- class pynetdicom.pdu_primitives.SCP_SCU_RoleSelectionNegotiation¶
A representation of the SCP/SCU Role Selection Negotiation primitive.
Allows peer AEs to negotiate the roles in which they will serve for each SOP Class or Meta SOP Class supported on the association. This negotiation is optional.
The association Requestor may use one SCP/SCU Role Selection item for each SOP Class as identified by its corresponding Abstract Syntax Name and shall be one of three role values:
Requestor is SCU only
Requestor is SCP only
Requestor is both SCU/SCP
If the SCP/SCU Role Selection item is absent the default role for a Requestor is SCU and for an Acceptor is SCP.
Identical for both A-ASSOCIATE-RQ and A-ASSOCIATE-AC.
- sop_class_uid¶
The UID of the corresponding Abstract Syntax
- Type
pydicom.uid.UID, bytes or str
- scu_role¶
False
for non-support of the SCU role,True
for support.- Type
bool
- scp_role¶
False
for non-support of the SCP role,True
for support.- Type
bool
Examples
