A.4.1 Definition of Support
A capability is said to be supported if the Implementation Under Test (IUT) is able:
•
to generate the corresponding service parameters (either automatically or because
the end user explicitly requires that capability);
•
to interpret, handle and when required make available to the end user the
corresponding service parameter(s).
A capability is referred to as either an originator capability “O” (when the MHS end-
user is acting as originator) or a recipient capability “R” (when the MHS end-user is
acting as recipient).
A protocol element is said to be supported for origination if the IUT is able to generate it
under some circumstances (either automatically or because end-user explicitly requires a
related capability).
A protocol element is said to be supported for reception if it is correctly interpreted and
handled and also, when required, made available to the end-user.
A.4.2 D (Defined) Column
This column indicates the level of support required for conformance to the CCITT
Recommendation.
The values are as follows:
A.4.3 I (Implemented) Column
This column shall be completed by the supplier or implementor, when a “[ ]” is present,
to indicate the level of implementation of each item. The proforma has been designed
such that the only entries required in that column are:
Symbol Meaning
m Mandatory support is required
o Optional support is permitted for conformance to the Recommendation. If implemented it
must conform to the specifications and restrictions contained in the Recommendation.
These restrictions may affect the optionality of other items
c The item is conditional, the support of this item is subject to a predicate which is
referenced in the note column
n/a The item is not applicable
Symbol Meaning
Y Yes, the item has been implemented
N No, the item has not been implemented
— The item is not applicable
