ImplementationVersionNameSubItem
¶ An Implementation Version Name Sub-item.
The Implementation Version Name Sub-item allows communicating Application Entities to identify each other at Association establishment.
-
implementation_version_name
¶ The Implementation Version Name field value, 1 to 16 characters.
Type: bytes or None
-
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 (0x55).
Type: int
Notes
The Implementation Class UID Sub Item requires the following parameters:
- Item type (1, fixed, 0x55)
- Item length (1)
- Implementation version name (1)
Implementation Version Name
The Implementation Version Name shall be encoded as a string of 1 to 16 ISO 646:1990 (basic G0 set) characters.
Encoding
When encoded, an Implementation Version Name Sub-item has the following structure, taken from Tables D.3-3 and D.3-4 [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 Variable Implementation version name References
