THAILAND, SITTI SUPPLY

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.
