Specialist Task Force 429:
Test Specifications for the Interoperability of Digital Selective Calling (DSC) Marine Radios

Who we are:

Team Leader: Sebastian Mueller
Team Members: Andras Kovacs
Pete Hizzey


What we do:

STF429 was created to develop interoperability standards for the maritime Digital Selective Calling (DSC) protocol that is outlined in ITU-R M.493. ETSI TG26 has already developed a series of product standards for each class of DSC with the EN300 338 multipart standard.

This STF is taking the requirements of each of the ETSI class standards and writing a complete series of interoperability tests that may be used to demonstrate functional compliance between compatible equipment.

For more details, see our Terms of Reference

Why we do it:

Significant changes have been made recently to the operational and user interface requirements for DSC. Whilst the ETSI DSC class standards give the exact requirements in a text based format, it was considered extremely beneficial to equipment designers and software developers to also have a parallel set of functional interoperability standards.

How we do it:

The STF experts work in collaboration with the ETSI TG26 Maritime committee in a series of work sessions planned through summer and autumn of 2011.


The primary output of the STF will be a set of interop standards (Test Descriptions) for each class of DSC. Each of these will be directly related to a part of the EN300 338 multipart standard.

There will also be a general requirements catalogue covering all classes of DSC.

Time plan:

These standards are scheduled for approval in November 2011 at ETSI ERM#45.

First drafts will be presented to ETSI ERM#44 in July.
