Conformance and Interoperatility Presentation Encoding of FTAM PDUs and Data

When receiving PDUs, Compaq FTAM supports all three options listed above. When sending PDUs, Compaq FTAM follows these rules:

•If single FTAM PDUs are to be sent, they are placed in a single PDV list encoded as single-ASN1-type.

•If multiple FTAM PDUs are to be sent (grouped requests or responses), they are sent in a single PDV list encoded as single-ASN1-type.

•When F-DATA requests are sent by the Compaq responder, the method of encoding depends on the number of data elements to be encoded. If only a single data element is to be sent, it is placed in a single PDV list encoded as single-ASN1-type. If more than one data element is to be sent, the data elements are placed in a single PDV list, encoded as octet-aligned.

For FTAM-2 files, node-descriptor data elements are placed in their own PDV lists as single-ASN1-type. Consecutive file-contents data elements are placed in a single PDV list as either single-ASN1-type or octet-aligned, depending on whether one or more consecutive data elements exist.
