pynetdicom.pdu_primitives.SOPClassExtendedNegotiation¶

class pynetdicom.pdu_primitives.SOPClassExtendedNegotiation[source]¶

A representation of the SOP Class Extended Negotiation primitive.

Allows peer AEs to exchange application information defined by specific Service Class specifications. Each Service Class is required to document the application information it supports and how this information is negotiated between SCUs and SCPs.

The SOP Class Extended Negotiation is optional and there may only be a single SOPClassExtendedNegotiation item for each available SOP Class UID.

Identical for both A-ASSOCIATE-RQ and A-ASSOCIATE-AC

sop_class_uid¶

The UID of the SOP Class

Type: pydicom.uid.UID, bytes or str

service_class_application_information¶

The Service Class Application Information as per the Service Class Specifications in Part 4 of the DICOM Standard.

Type: bytes

Examples

>>> from pynetdicom.pdu_primitives import SOPClassExtendedNegotiation
>>> item = SOPClassExtendedNegotiation()
>>> item.sop_class_uid = '1.2.840.10008.5.1.4.1.2.1.3'
>>> item.service_class_application_information = b'\x01'
