The presence of SITTI in India dates back many years ago. During the past decades, SITTI has been supplying Voice Communication Systems (VCS) (and ancillary equipment) used by hundreds of controllers in the main ACC centres and international airports of India. These systems have been recently complemented by a nationwide coverage of new VoIP (Voice over IP) VCS systems that have been installed throughout the entire Nation.

SITTI is a world leader in Air Traffic Control (ATC), focusing on Voice Communication Systems (VCS), recorders, consoles and auxiliary devices used at ACCs and towers of any size, from small airfields to very large international sites. Our presence in India covers the whole subcontinent, and it is expected that our contribution to the local economy will still increase in the near future.

In order to consolidate and expand its strong relationship with the Airport Authority of India (AAI), and to provide immediate answer to any request that may come from the local market, SITTI decided to establish a new subsidiary company in India under the name of “SITTI COMMUNICATIONS INDIA PRIVATE LIMITED” (also simply called “SITTI INDIA“), with its headquarters in New Delhi.

This investment testifies the growing importance for SITTI of India in the region. The constantly evolving systems, that are more and more integrating new features to give air traffic controller complete situational awareness, see SITTI in the forefront of the innovation projects worldwide. The presence of a local subsidiary will give Indian ATC authorities the opportunity of lively experimenting the new functions through the direct contact with local qualified staff.

SITTI  provided installation, configuration, setting to work, integration, commissioning and onsite training for a MULTIFONO^® M800IP^® Voice Communication System (VCS) including a number of Controller Working Positions (CWP) with Radio, Telephone and Intercom facilities in Azerbaijan.

This system was  destined for  Zangilan International Airport, thus improving the capability of the local air traffic control authorities to manage the aircrafts flows over the country. The M800IP^® VCS provided by SITTI is intended to interface both analogue telephones and VHF/UHF radios, by also allowing controllers to share information and access remote radios according to their needs.

In addition, a Voice Recording System (VRS) will provide legal recording functions for a significant number of VoIP (Voice over IP) streams and analogue channels.

The SITTI’s VCS being supplied to Azerbaijan has been designed to be natively compliant to the EUROCAE ED137 standard requirements. This latter is an internationally consolidated standard that defines the way VoIP shall be used in the ATM/ATC fields. SITTI is proud of having been a true pioneer in the development and deployment of such VoIP systems worldwide.

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

Myanmar (former Burma) is a strategic country for aircrafts flying between Europe and the Far East and Australia. The modernization of the local infrastructures already saw SITTI in the forefront with the supply of a MULTIFONO® M800IP® Voice Communication System (VCS) to the Air Control Centre (ACC) in Yangon, the capital city (as witnessed here: https://www.sitti.it/sitti-for-the-far-east).

About a year later, another VCS has been delivered to the same premises (please read here: https://www.sitti.it/simulation-in-myanmar-by-sitti), this time for simulation purposes at ACC level. Simulation systems are of fundamental importance to allow controllers to get acquainted with the system they will be using in their daily work. Through them, it is also possible to simulate abnormal conditions that may jeopardize the ordinary Air Traffic Management, thus increasing the situational awareness of the operators.

Through the SAMART Group, a Thai company very active in the region and that already proposed our products for their high reliability, SITTI has been asked to provide a further step in the local air traffic control environment, by supplying another simulation system, this time to the Civil Aviation Training Institute (CATI) under the Department of Civil Aviation (DCA) for training both controllers and aviation students.

The VCS that will be installed for simulation purposes belongs to the same MULTIFONO® family and therefore it inherits the same levels of capability and reliability. More specifically, it is a M801IP system equipped with 6 controller working positions (CWP) and a communications dispatching server, also used for configuration purposes.

The combined presence of systems all developed by SITTI, primary VCS manufacturer and supplier worldwide, ensures the customer that all his needs are properly addressed through top edge solutions, both in the Civil and Military fields. The leading edge, redundant, non-blocking architecture of the MULTIFONO® Voice Communication Systems provide flexibility and modularity for easy expansion and addition of further functionalities.

In 2019, after strong competition, AAI (Airport Authority of India) awarded SITTI a major contract for the delivery of a large number of Voice Communication (VCS) and Voice Recording Systems (VRS) to serve the whole Nation.

Following a detailed installation plan, the delivered systems have been put gradually into service, according to the identified AAI needs and requirements. SITTI is glad to be in the position of announcing that another set of systems successfully completed their SAT (Site Acceptance Test) and are ready for entering into real operation at the following cities:

• Bhavnagar
• Bhopal
• Dimapur
• Hubli
• Trichy
• Vadodara
• Raipur
• HAL Bangalore

These Voice Communication Systems belong to the top performing MULTIFONO® M800IP® family, fully compliant to the international ED 137 VoIP standard for VoIP applications in the Air Traffic Control field. They are in charge of managing local and remote radio stations, where appropriate gateway devices grant the possibility of taking full advantage of the standard ED 137 performances.

The provision of such a large number of systems and ancillary equipment to the Airport Authority of India comes after other successful projects in the same area, where SITTI products have been found as the best choice for the fulfilment of the challenging requirements set by the management of big air traffic movements. Thanks to the supplied systems and the extraordinary positive reputation gained in many years of presence in India through other large projects, SITTI is proud of supporting AAI to further contribute to the development of the Indian region.

The long-term presence in the market of mission-critical systems for very demanding customers allows SITTI to present its solutions to all organisations where secure, reliable and controlled communications are required through integrated communication solutions, with high efficiency and effectiveness for flight safety.

The air traffic over the Maldives archipelago is already managed through a SITTI system that was installed some years ago. The connectivity from VCS to the radio sites have been recently converted from analogue to MPLS, hence there is a need to connect the radio devices to the existing MULTIFONO® system via a WAN.

The interface to the new radio sites is going to be granted by means of SITTI GVS gateways (Gateway Voice System), that provide the capability of converting analogue signals to standard VoIP messages and protocols, thus allowing any kind of radio equipment to be interfaced over a LAN or WAN. Similar gateways are also available for telephone links.

GVS devices have been conceived to provide the Customers with a powerful and a cost-effective solution to handle legacy analogue connections and convert them to the latest VoIP technology, in accordance with EUROCAE VoIP Recommendations (ED136, ED137, ED138). These products are characterized by very high flexibility, expansibility, modularity, reliability, in line with the overall architectural principles that drive all SITTI VCSs (Voice Communication System).

Remote radios are connected over the WAN via unicast IP links (RTP) that are automatically transformed into an internal multicast IP session, to allow many different controllers to access the same radio while saving bandwidth on the connecting WAN. Thanks to two independent Ethernet connections to the internal LAN and other two connections to the external WAN, GVSs ensure redundancy and non-blocking 24-7-365 functioning.

Once again, even through the provision of VoIP radio gateways to Maldives, SITTI proved its being a complete solution provider, helping the customer to properly deal with all voice interfaces that are made seamlessly available to the controllers, regardless of their being analogue or standard VoIP.
