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.
