A.4.1 Definition of Support
A.4.2 Status Columns (PS)
This column indicates the level of support required for conformance to the ISO/IEC
standard (PS column). The values are as follows:
The Initiator (Init) indicates that the implementation under the IUT is a sending DSP
and the Status Resp indicates that the implementation under the IUT is a responding
DSP.
A.4.3 Support Column
This column shall be completed by the supplier or implementor, when either a [ ] or a
( ), to indicate
the level of implementation of each item. The proforma has designed such that values
required in are:
In the PICS proforma tables, every leading item marked 'm' shall be supported by the
IUT. Sub-items marked ‘m’ shall be supported if the corresponding leading item is
supported by the IUT.
All entries within the PICS proforma shall be made in ink. Alterations to such entries
shall be made by crossing out, not erasing nor making the original entry illegible, and
writing the new entry alongside. All such alterations to records shall be initialized by
the staff making them.
A.4.4 Note Column
This column indicates the following:
m mandatory support is required;
o optional support is permitted for conformance to the standard. If implemented it must
conform to the specifications and restrictions contained in the standard. These restrictions
may affect the optionality of other items;
c the item is conditional (support of the capability is subject to a predicate);
c:m the item is mandatory if the predicate is true, optional otherwise;
— the item is not applicable;
i the item is outside the scope of this PICS;
TBS the item status has not been determined
? the item status has not been determined; m should be assumed until a resolution is made
Y yes, the item has been implemented;
N no, the item has not been implemented;
— the item is not applicable;
notexx refers to Note xx;
d(xx) a default value xx within ( ) is defined in the Standard. When absent in the PDU, both
sender and receiver shall interpret it as having the default value specified in the standard
