F.7 Elements of Procedures Related to SPDUs

F.7.0 Guidance for Completion

Note on GT and PT SPDUs

The use of GT and PT SPDUs in the following tables is implicitly dependent on the

associated functional unit.

Note on D Column

As protocol elements, SPDUs are considered in both directions:

•

A “sending SPDU” item is marked as not-mandatory (“o”) if this feature is attached:

•

either to a not-mandatory protocol mechanism

•

or to a free behavior of the SS-user

•

A “receiving SPDU” item is marked as not-mandatory (“o”) if this feature:

•

either is attached to a not-mandatory protocol mechanism

•

or is an SS-user confirmation associated to a free SS-user request sending

(marked as not-mandatory)
