TASSTA relaunches its 3GPP mission-critical server as T.XON

TASSTA has renamed and rebuilt its 3GPP mission-critical (MCX) server. Until now known as T.Quasar, it continues as T.XON 11.0; the first releases, 11.4.1 and 11.5.0, shipped in September 2026.

The headline feature is site replication: a T.XON deployment can run across sites, and when one site goes down the talk groups keep running on the other. Release 11.4.1 carries 128 features across server, administration and recording.
T.XON is the core of an environment TASSTA develops and releases as one product:

T.Star client for Android handsets;
T.Galaxy dispatcher;
T.Admin administration centre;
T.Writer recording;
T.Gravity gateway that brings TETRA, DMR and analogue radio fleets into the same talk groups.

The server is documented as open to other vendors’ MCX clients and ETSI-compliant user equipment.
For existing customers only the name changes: same versions, roadmap and support, and existing documentation links keep working.
“Buyers want a working system, not a set of parts they have to make work together,” said Kaveh Hosseinzadeh, Managing Director of TASSTA. “T.XON is the name of that system.”

TASSTA shows the T.XON environment at PMRExpo, 24 to 26 November 2026, Koelnmesse Cologne, stand E048-F049.
