SITTI systems are designed to work without interruption for tens of years, thus guaranteeing customers extremely high reliability figures. This is one of the things SITTI is particularly proud of, because it gives clients the perception of a stable and always available system, which he can rely upon. Of course this also increases the positive reputation of SITTI far beyond South America.

As said above, SITTI VCS (Voice Communication System) systems are very reliable, so that unit replacement and fault repair activities are quite infrequent. The major CINDACTA Air Traffic Control centres in Brazil (Brasilia, Curitiba, Recife and Manaus) are under a maintenance contract with SITTI that provides technical, functional and system assistance to cope with any possible degradation or disruption.

The current maintenance contract envisages the physical presence of a SITTI engineer at each control centre during working hours 5 days a week, accompanied by the constant 24/7 availability on call in case of any urgency. Should anything serious occur that cannot be solved over the phone, a qualified engineer is guaranteed to be on site within 60 minutes.

Programmed maintenance activities are scheduled to be executed daily, weekly or monthly, according to the system parts to be supervised. Every month, a written report is prepared and handed over to the customers, listing all activities carried out and their outcome.

The current maintenance contract also includes the same kind of service for the CRCEA-SE centre in Sao Paulo and the APP military and civil control centre responsible for the Sao Paulo and Rio de Janeiro areas. In addition, an annual similar maintenance program applies to the other about 30 DTCEA centres providing APP and TWR service, with constant helpdesk contacts and on site intervention within 24 hours in case of blocking problems.


On November 9, 2022, at 6:20 am, an earthquake hit the Adriatic coast, near the cities of Pesaro and Ancona, Central Italy. The earthquake magnitude was not devastating, however it understandably created apprehension in the population that felt its tremors and was scared of possible serious consequences that, thanks God, did not occur.

On that day, the local fire brigades received about 1000 calls asking for help and requests of site inspections for making sure infrastructures and buildings and houses were safe to use, work or live in. The Pesaro operative room is equipped with SITTI MULTIFONO® M800IP® voice communication system (VCS) with 3 VoIP (voice over IP) operator working positions that were able to cope with all incoming calls and properly dispatch orders to the fire brigades patrols on the territory.

The VCS system has been under stress for many hours, representing the focal point for the communications between the operative command and the firefighters operating in the area. The reliability and continuous availability of the system, its capability of queuing calls and properly connecting operators, allowed it to provide an excellent service, so that all emergency calls have been duly managed and processed, even during the following days when more than 2000 further calls have been received for the same reasons.

The operative and control room in Ancona thanked SITTI for the unparalleled good quality of the system they have been using. His words are the best advertisement for our products. “This further encourages us to enhance and improve our products” – Mr. Federico Di Guida, head of SITTI maintenance department said – “to continue providing our customer with top-edge systems and services.


COCESNA (Corporación Centroamericana de Servicios de Navegación Aérea) is undergoing a project for the modernization and extension of the air traffic control capacity and features in Central America. In the frame of this project, there’s the need for a new VCS (Voice Communication System) system for the ACC (Area Control Centre) in Tegucigalpa Honduras. The VCS  will be installed in the CENAMER ACC of Tegucigalpa, the capital of Honduras.

COCESNA awarded SITTI the relevant contract for the supply of the VCS system. The new system belongs to the SYNCRONIS® MULTIFONO® M800IP® family that  hasproven its reliability and flexibility in many other installations all over the world, particularly in America.

The VCS system includes 15 touchscreen CWPs (Controller Working Positions) through which ATCOs (Air Traffic Controller Operators) can seamlessly access the radio and telephone communications features provided by the VCS, regardless of whether they are analogue, digital or VoIP (Voice Over IP). All protocol conversions are completely transparent to the user.

A large number of VoIP radios (57), analogue telephone circuits (36), IP telephone channels (10) and the CWPs are fully integrated to provide controllers the fastest possible and most reliable access to the respective links and lines. All this features, coupled with the native flexibility and expandability of the system, heavily contributes to make their work easier and more comfortable,  making the skies safer.

SITTI is a primary VCS manufacturer and supplier worldwide, capable of giving prompt and topedge solution answers to Customer needs, both in the Civil and Military fields. The leading edge, redundant, non-blocking architecture of the SYNCRONIS® MULTIFONO® M800IP® provides flexibility and modularity for easy expansion and addition of further functionalities.


Arica is a medium size city in Northern Chile, close to the border with Peru. Arica is an important harbor where goods are shipped for the inland and neighboring countries and is also the end station of the Bolivian oil pipeline. The strategic position of this city is enhanced by being served by a busy international airport.

COMSA Instalaciones y Sistemas Industriales, a big (Spanish) infrastructure company, in the frame of large modernization activities at the airport, awarded SITTI a contract for the supply of a new Voice Communication System (VCS) at the local Aeropuerto Chacalluta de Arica (ARI), including Controller Working Positions (CWP), Radio and Intercom facilities.

The system being provided by SITTI belongs to the MULTIFONO® M800IP® family of Voice Communication Systems that has already been installed at many other aeronautical sites in Chile, from North to South.

A large number of analogue and hotline telephone lines are interfaced to the VCS by means of 32 dedicated modules that allow connection to the system’s VoIP internal network. Another 12 SIP telephone lines are connected through 3 dedicated boards that make it possible for ATCOs (Air Traffic Control Operators) to seamlessly  communicate through all kinds of available links.

Similarly, both analogue and native VoIP radios are interfaced to the M800IP® system by means of a total of 14 radio interface boards for the connection of 28 analogue radios, plus another 4 VoIP cards to get access to up to 16 VoIP radios. Best Signal Selection facilities are also included in the system.

ATCOs access all provided communication features through  touchscreen Controller Working Positions (CWP) that are also equipped with GPS-synchronized IP clock displays manufactured by SITTI.

The Arica system is expected to get final operational approval in the first months of next year.


Following a safety requirement from the Italian aviation regulator (ENAC), the national Air Navigation Service Provider (ENAV) asked SITTI to implement a radio override feature between the Malpensa airport and the Linate ACC.

The safety requirement applies to airports with two parallel runways. It states that parallel operations can be carried out, provided a higher level management entity (the ACC) is possibly capable (e.g. in case of emergency) of taking control of the radios used at the airport.

The implementation of this feature was greatly facilitated by the native flexibility and integrated solution provided by the MULTIFONO® Voice Communication Systems (VCS) by SITTI.
