Level of support This byte field defines the supported storage level of the
Association-acceptor. It shall be encoded as an
unsigned binary integer and shall use one of the
following values:
0 - level 0 SCP
1 - level 1 SCP
2 - level 2 SCP
3 - N/A - Association-acceptor is SCU only
If extended negotiation is not supported, no
assumptions shall be made by the Association-
requester about the capabilities of the Association-
acceptor based upon this extended negotiation.
Level of Digital A Level 2 SCP may further define its behavior in this
Signature support byte field.
0 – The signature level is unspecified, the AE is an
SCU only, or the AE is not a level 2 SCP
1 – signature level 1
2 – signature level 2
3 – signature level 3
If extended negotiation is not supported, no
assumptions shall be made by the Association-
requester about the capabilities of the Association-
acceptor based upon this extended negotiation.
Element Coercion This byte field defines whether the Association-acceptor
may coerce Data Elements. It shall be encoded as an
unsigned binary integer and shall use one of the
following values:
0 - does not coerce any Data Element
1 - may coerce Data Elements
2 - N/A - Association-acceptor is SCU only
If extended negotiation is not supported, no
assumptions shall be made by the Association-
requester about the capabilities of the Association-
acceptor based upon this extended negotiation.
