35 years
telecommunications.

From the first systems in Slovenia to international references across Europe and beyond.

The company was established for the purpose of selling, designing, providing consultancy for, and maintaining telecommunications systems.

We were among the first to begin building telecommunications backbone systems.

During this period of growth and development, we participated in projects across Southeast and Western Europe and, through international references, solidified our position as a reliable partner in the field of telecommunications systems.

Alongside the evolution of telecommunications technologies—and while undertaking increasingly large and complex projects—we have grown from a local player into an internationally recognized systems integrator with a track record spanning 24 countries.
