A.3 Instructions for Completing the PICS Proforma
An item is said to be supported for origination if the IUT is able to generate it under
some circumstances (either automatically or because the end-user explicitly requires a
related service).
An item is said to be supported for reception (relay) if it is correctly interpreted and
handled and also, when required, made available to the end-user.
Each line within the PICS proforma which requires implementation detail to be entered
is numbered at the left hand edge of the line. This numbering is included as a means of
uniquely identifying all possible implementation detail within the PICS proforma.
In the “D” (Defined) column a preprinted attribute reflects the conformance
requirement defined in the P1 Protocol standard. The following classification is used:
A response in the “D” (Defined) column of C p1 for Alternate Recipient Allowed, for
example, means that support of the capability is mandatory if p1 is true. Otherwise,
support of the capability is optional. A response of P1=A.5.4.3.R means that p1 is true
if the element of service “Alternate Recipient Assignment” is supported in reception.
Definition of predicates used in the commented P1 PICS:
Ref. No. Question Response
1 Are all mandatory capabilities implemented? Yes
Symbol Meaning
m Mandatory (the implementation must support the item).
o Optional (the implementation may support the item).
c Conditional (support of the capability is subject to a predicate). See example below.
— Not defined or not applicable.
