In the second half of December 2020, ENAV made a significant step forward towards the full introduction of the VoIP technology in their Air Traffic Control infrastructure. Few weeks ago, in fact, SITTI concluded activities for putting operative the new VoIP system at Rome Fiumicino international airport. This airport is the main Italian hub, providing long-haul connections to all continents.

Rome Fiumicino airport will be using SITTI MULTIFONO M800IP® main Voice Communication System (VCS), equipped with analogue and digital radio and telephone channels, plus a number of standard ED-137 VoIP connections. To ensure connectivity to ENET (the legacy voice and data network utilized by ENAV to interconnect their ACCs and airports), appropriate QSIG interfaces are also envisaged. All these different kinds of interfaces are natively supported by the M800IP® system, thus providing the customer with all the interface points needed, by taking full advantage of the ED 137 standard recommendations and practices. Digital recorders are used for legal recording.

Besides the VCS system, SITTI is also supplying ENAV with new controller working position consoles, capable of being assigned any operative role through simple configuration patterns. This guarantees maximum flexibility and interoperability in case of operational rearrangement and/or maintenance activities. The new consoles have been designed, on innovatice requirements issued by ENAV, and manufactured by SITTI with special attention to ergonomy and integration of diversified data and service sources, in the frame of the “NexTower” project by ENAV, aiming at the technological modernization of all air traffic control rooms and airport towers.

The successful completion of the installation, the subsequent in-depth tests and final commissioning in Rome Fiumicino are major steps for the improvement of air traffic from/to the capital of Italy, so as to be ready when the pandemic crisis will be over and the amount of traffic will increase. SITTI is proud to have given its contribution to this project.


Through the excellent relationships with LEONARDO, SITTI has been awarded the supply of a Voice Communication System (VCS) for the U-Tapao airport in Thailand, about 40 kilometres afar from the world famous beaches of Pattaya and about 160 km from the capital, Bangkok.

SITTI is being supplying a VCS belonging to the MULTIFONO® M800IP® family, including 7 Controller Working Positions (CWP) with Radio, Telephone and Intercom facilities. Installation, configuration, setting to work, integration, commissioning are under the responsibility of SITTI.

The system for U-Tapao airport is aimed at allowing the final customer to interface 32 standard analogue telephone lines of different kinds and 12 analogue radio channels. Nevertheless, the interface boards making up this system are already natively ready to be used for connecting VoIP radios, once the customer will be migrating to this technology.

Best Signal Selection (BSS) modules are also part of the system for identification and distribution of the best received radio signal to the operators. Furthermore, interfaces for legal recording are also envisaged. The supply also includes precise clock reference modules and the MMS software platform used to configure the system, manage possible incoming alarms and make all administrative tasks from a redundant installation.

At any time in the future, the system can be seamlessly enlarged by adding new interface boards and/or controller working positions, whose configuration is extremely easy and straightforward: they can be put into operation in a matter of minutes, without interrupting ongoing activities.
