Slide 2
TTCN-3 language evolution
 Tasks
 Resolution and implementation of CRs,
Prepare the drafts for ETSI publication.
Scope:
Parts 1 and 4 to 10 of the ES 201 873 series
The 4 extension packages (ES 202 781, ~782, ~784, ~785)
Proforma for TTCN-3 reference test suite
 Cooperation with STF 160 on language requirements of LTE testing
(interim version around middle of the year)
 Cooperation with STF409 on Development of TTCN-3 conformance test
suite
 Two new language extension packages
 Advanced TRI
 Continuous Signal support
 „Maintenance“ work (i.e. no new standard is developed)
 Except reporting problems, CRs are often requesting smaller additions,
new fearures -> TTCN-3 „maintenance“ also includes development work

Slide 3
Major new features in the coming new version
(my selection )
 Map and unmap operations can be parameterized
 Port-specific address type can be declared in the port type
definition
 Specifying the host for a newly created PTC in the TTCN-3
code
 Consolidation and simplifying the BNF (using tool support)
 Adding XSD element and type substitution to XSD to TTCN-3
mapping
 int2enum() predefined function
 ispresent() can be used for templates of all types, not only
for optional fields
 New source code documentation tags:
 @requirement, @status, @reference
 @verdict tag is extended for TTCN-3 modules
(check the details in Mantis @ http://t-ort.etsi.org/view_all_bug_page.php)
