The Hua Hin International Airport, near Bangkok, required 3 Voice Communication Systems (VCS) for widening the scope and depth of its air traffic control capabilities. Through its local reprensative, V&S COMMUNICATION Ltd, SITTI has been awarded this supply.

The VCS systems are used at the airport according to an double redundancy mode:
• The main VCS system is utilized for normal operations (MOPS)
• Should the main system be for any reason not available, the second VCS (fallback) will take over
• Should even the fallback system be unavailable, the third system (CON/TRA) will be replace the faulty systems and guarantee full and safe air traffic control by simple reconfiguration

While the main and fallback systems are very similar in size and interfacing capability (12 controller working position each, plus 60 analogue + VoIP radio channels, 30 telephone lines, GPS precision distribution clock), the CON/TRA system has originally been thought of as a training (TRA) system. In case of emergency (when the other two systems are not available), this latter system can enter into service as a contingency (CON) system. Although slightly less equipped (8 CMP, 40 radios, 24 telephone lines), this will allow local air traffic controllers to continue their work even in the toughest conditions, thus guaranteeing safe and uninterrupted service to aircrafts.

SITTI is a primary VCS manufacturer and supplier worldwide, capable of giving prompt and top edge solutions 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.

The presence of SITTI in the Indian sub-continent expands, thanks to the recent contract signed with AASL (Airport and Aviation Services [Sri Lanka] Limited), the Sri Lankan Air Navigation Service Provider and also the Civil Airports Operator. The contract covers one of the key elements in the modernization of the Sri Lanka’s aviation infrastructure in keeping with the latest technological developments in the Air Traffic Communications, with the supply of two brand new Voice Communication Systems (VCS) in Bandaranaike International Airport (BIA) and Colombo Airport, Ratmalana (RMA), and the installation of new VOIP radio transmitters and receivers (provided by JOTRON).

The two Voice Communication Systems belong to the MULTIFONO® M800IP® family. The significant number of requested features and interfaces are supported by M800IP® with the purpose of creating an integrated network between the two sites, so that operators on one site can access resources belonging to the other site, according to Customer policies. The BIA system envisages 23 Controller Working Positions (CWP), 24 VOIP radio channels, 66 analogue radios, more than 120 telephone lines (VOIP+analogue), while the system in Ratmalana encompasses other 25 CWPs, more than 70 telephone lines and 68 radio channels (VOIP+analogue). The two systems are interconnected via E1 and VOIP links to allow resource sharing.

The high level of functions integration at all CWPs allows controllers to safely, easily and intuitively interface both Telephone connections and Radio communication facilities provided by the MULTIFONO® M800IP® VCS system, which provides resource site-sharing capabilities, e.g. making it possible to define which radios on one site can be directly accessed from another site.
