TRANSFER-SYNTAX - define the transfer syntax

You only need the TRANSFER-SYNTAX control statement when you want to define your own application context for communication based on the OSI TP protocol (see the APPLICATION-CONTEXT statement in section "APPLICATION-CONTEXT - define the application context").

It allows you to define a local name for a transfer syntax, and to assign an object identifier. The transfer syntax determines the rules governing the encoding and decoding of the abstract syntax defined in the object identifier.

The transfer syntax defined here must be supported by the OSS version used. OSS only supports the BER transfer syntax at the present time.

TRANSFER-SYNTAX

transfer_syntax_name    ,OBJECT-IDENTIFIER=object_identifier

transfer_syntax_name

Local name for a transfer syntax up to eight characters in length. This name must be unique within the UTM application. The transfer_syntax_name BER (Basic Encoding Rules) is reserved.

OBJECT-IDENTIFIER=

object_identifier Object identifier of the transfer syntax specified as follows: object_identifier=(number1,number2, ... ,number10) number is a positive integer in the range 0 to 67108863. For object_identifier, you can specify two to ten integers enclosed in parentheses, each of which is separated by a comma. The number of integers entered and their positions are relevant. Instead of the integer itself, you can also specify the symbolic name assigned to this integer. The table in section "OSI terms" shows the permitted values for number at the various positions. object_identifier must be unique within the UTM application, i.e. another transfer syntax must not be generated with the same object identifier.

openUTM generates the BER transfer syntax by default:

TRANSFER-SYNTAX BER,                          -
                OBJECT-IDENTIFIER=(2, 1, 1)   -

Symbolic description of the object identifier:
