##### D.3.3.3.2 Asynchronous Operations Window Sub-Item Structure (A-ASSOCIATE-AC)

The Asynchronous Operations Window Sub-Item shall be made of a sequence of mandatory fixed length fields. This Sub-Item is optional and if supported, only one Asynchronous Operations Window Sub-Item shall be present in the User Data Item of the A-ASSOCIATE-AC. Table D.3-8 shows the sequence of the mandatory fields.

Table D.3-8. Asynchronous Operations Window Sub-Item Fields (A-ASSOCIATE-AC)

Item Bytes | Field Name | Description of Field
--- | --- | ---
1 | Item-type | 53H
2 | Reserved | This reserved field shall be sent with a value 00H but not tested to this value when received.
3 - 4 | Item-length | This Item-length shall be the number of bytes from the first byte of the following field to the last byte of the Maximum-number-operations-performed field. In the case of this Sub-Item, it shall have the fixed value of 00000004H encoded as an unsigned binary number.
5-6 | Maximum-number-operations-invoked | This field shall contain the Maximum-number-operations-invoked as defined for the Association-acceptor in Section D.3.3.3 It shall be encoded as an unsigned binary number.
7-8 | Maximum-number-operations-performed | This field shall contain the Maximum-number-operations-performed as defined for the Association-acceptor in Section D.3.3.3. It shall be encoded as an unsigned binary number.
