UserIdentitySubItemAC
¶ A User Identity (AC) Sub-item.
A User Identity (AC) Sub-item is used to response with the server identity to the association requestor.
-
item_length
¶ The number of bytes from the first byte following the Item Length field to the last byte of the Item.
Type: int
-
item_type
¶ The Item Type field value (0x59).
Type: int
-
server_response_length
¶ The Server Response Length field value.
Type: int
-
server_response
¶ The Server Response field value.
Type: bytes
Notes
A User Identity (RQ) Sub-item requires the following parameters:
- Item type (1, fixed, 0x59)
- Item length (1)
- Server response length (1)
- Server response (1)
Encoding
When encoded, a User Identity (AC) Sub-item has the following structure, taken from Tables D.3-15 [1] (offsets shown with Python indexing). Items are always encoded using Big Endian [2].
Offset Length Description 0 1 Item type 1 1 Reserved 2 2 Item length 4 2 Server response length 6 Variable Server response References
