SITTI RADIO GATEWAYS TO MALDIVES

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.

LAST RESORT SYSTEM BY SITTI

The Schiphol airport in Amsterdam (The Netherlands) is one of the busiest airports in the world, with over 50 million passengers transiting this airport in their tourism and business travels. The 6 airport runways allow a large number of flights to arrive and depart from/to all continents. Air Traffic Control the Netherlands (LVNL) is the ANSP (Air Navigation Service Provider) at Schiphol.

Safety is here a must: air traffic control shall be guaranteed in all circumstances, to allow a continuous orderly flow of aircrafts over this congested area. To ensure this in all circumstances, the voice management infrastructure of LVNL needs to be equipped with an emergency system to be used when the main and standby VCSs (voice communication systems) are for any reason not available.

The MULTIFONO® M800IP® Voice Switching System delivered by SITTI to LVNL is now extended to the remote sites of Eelde and Beek. For the implementation of a Centralised Base LVNL WAN connections are used to reach local radios from Schiphol. Since these latter are analogue receivers and transmitters, proper VoIP gateways by SITTI (named GVS) are installed at those sites to allow conversion of analogue signals to the standard ATC/ATM protocol, in conformance to EUROCAE ED-137.

The emergency system installed at Schiphol is called LRRTS (Last Resort Radio Telephone System): it allows operators to access local and remote radio and telephone resources in emergency conditions to assure the proper landing and departing of aircrafts, thus not creating a blocking situation that may result being very dangerous. The extension allows up to 10 controllers to access to local and remote radio and telephone links through dedicated panels.

Site acceptance test of this system is expected to take place in next July.

SITTI SERVER BASED VCS TO CZECH REPUBLIC

With the objective of enhancing the services provided, ANS-CZ (Air Navigation Services of the Czech Republic) have awarded SITTI the supply of two brand new VOIP server-based VCSs (Voice Communication Systems) to be installed at Prague Airport and Jeneč.

The M800IP-S systems based on COTS servers architecture being supplied to ANS-CZ are fully compliant to the most recent specifications set by the world famous EUROCAE ED-137 standard, which defines the way Voice Over IP (VOIP) shall be used for Air Traffic Control purposes.

The two systems that are going to be supplied to the Czech Republic have the capability of supporting 80 controller working positions (CWPs) that may be freely switched from one system to the other to cope with changing environmental and operational needs, without losing performance. The communication capability of the supplied systems is currently of 540 VoIP ED-137 radio channels and 100 VoIP telephone ED-137 links, although these figures can be expanded at any moment in the future with no detriment to the overall functionality and performance. Legal recording is also part of the supply.

 “We are very pleased of the award of these systems.” – Pietro Lucioli, SITTI dedicated program manager, said – “The introduction of these latest-generation VCSs will allow ANS-CZ fully exploiting the most recent technological achievements provided by M800IP-S for an extremely efficient and cost-effective management of the skies they are responsible for”.

VOIP GATEWAY BY SITTI IN MOZAMBIQUE

Beira is the second largest city in Mozambique, on the Indian Ocean with more than half a million people. Beira hosts the largest harbour in the area, which is of great importance for Mozambique itself, but even more for other neighbour countries that do not have direct access to the sea. All these aspects make of Beira a very important city, whose airport plays a fundamental role in the economy of the whole country.

The International Airport at Beira is currently using a voice communication system (VCS) by SITTI for the control of the air traffic in the region. The VCS installed at Beira belongs to the MULTIFONO® M600S family. This latter is using the TDM technology for allowing controllers to have access to the communication facilities of the airport.

VOIP is going to be gradually introduced in the country. Because of the different technology used, VOIP radios and telephone lines cannot be directly interfaced to the Voice Communication System. To allow them to be effectively connected to the VCS, an appropriate VOIP Gateway System shall be installed, capable of converting different protocols and signals.

This is the task performed by SITTI’s Gateway Voice System (GVS) that makes it possible for the customer to continue using the current TDM system and at the same time interface and fully use new VOIP radios and telephone lines. Each card in the GVS can handle up to 8 connections to remote radios or telephones, thus giving Beira International Airport all needed communication capacity.

SITTI LANDS ON THE HAINAN ISLAND

Haikou is the main city on the isle of Hainan, in the south of China. It is the most populated city on the island with almost 2 million people. For the improvement and expansion of the local airport, SITTI has been awarded the supply of a brand new MULTIFONO® M800IP® Voice Communication Solution (VCS), through the very good work and capabilities of our local representative, Beijing XiDi Communication Technology Co., Ltd.

Over the past years, SITTI has been installing a large number of VCS systems throughout China. The new order coming from this big country underlines and makes explicit the excellent reputation that our company has gained in the Far East, thanks to its top level systems, capable of adapting themselves to many different environments and capable of managing the Air Traffic Control of small airfields as well as large ACC centres.

The new VCS has been thought for the improvement and increase of the traffic management capacity of the local Haikou Meilan International Airport. It envisages a set of controller working positions, capable of interfacing both analogue and digital radios and telephone lines, with all the features and facilities available at larger installations.

This allows the system to get all benefits from the native straightforward flexibility of its MULTIFONO® IP-based architecture, without losing the possibility of providing full access to all kinds of interfaces and lines. The system is fully complying with the most recent standards issued by EUROCAE in its ED-137, which defined the rules for the use of VoIP (Voice over IP) in the Air Traffic Control and Management fields.

The new system is seamlessly expandable at any moment in time by simply adding new controller working positions and/or modules. Their configuration can be autonomously carried out by the local staff by means of the supervision and maintenance system, which is also part of the supply: they can be put into operation in a matter of minutes, thus significantly enhancing the air traffic control capabilities of Haikou operators.

MODERNIZATION OF ENAV VCS INFRASTRUCTURE

In order to properly phase the introduction of the new VOIP technology at their premises, ENAV issued a tender for the definition of a Frame Contract that would allow them to gradually acquire the systems, according to their needs and internal schedule. The Frame Contract is aimed at addressing all airports operating in Italy, both in their Main and Emergency configuration.

Each airport site has its own characteristics and specific needs that have been taken into consideration while discussing the contract, so that ENAV can ask SITTI to provide the solution elements that best suit the local requirements e.g. in terms of communication interfaces and controller working positions.

This gives ENAV the freedom to span their modernization process over a longer period of time, without losing the possibility of implementing the upgrade steps according to their internal programs and schedules. Whenever ENAV decides to start with the upgrade of a specific national or international airport in Italy, a specific executive proposal is being submitted by SITTI for ultimate ENAV approval.

Such technical proposal takes into consideration on one side the current radio and telephone connections at the designated site and on the other side the best solution elements (in terms of hardware and software modules) to fully support those interfaces and to provide additional standard VOIP features in full compliance with the latest national and international standards and recommendations.

For the time being, ENAV has already ordered SITTI the provision of the main systems for the following airports:

  • Milano Malpensa International Airport
  • Milano Linate International Airport
  • Rome Fiumicino International Airport
  • Bologna “Guglielmo Marconi”
  • Genova “Cristoforo Colombo”
  • Brescia “Gabriele D’Annunzio”
  • Rimini “Federico Fellini”
  • Treviso “Antonio Canova”

Two other VCS Systems for mobile towers have been commissioned and will be operational by mid 2021. A large number of radio and telephone connections have been migrated to the new M800IP® systems, thus significantly improving the overall signal quality and capability of managing devices of different kinds (analogue, digital, VOIP).

SITTI HELPS MOVING APP TO ACC

ENAV, the Italian Air Navigation Service Provider, is aiming at moving the approach (APP) function from the towers to the ACCs managing the relevant areas. This will make coordination between ACC and APP easier and more straightforward, and it will be releasing resources at the airport towers, that have been responsible for this service till now.

The move of the APP function to the ACC premises requires coordination with the towers involved, in such a way that communications with towers are guaranteed even in case of failure of the Voice Communication System of the ACC.

A new “intercom” network has been put in place, completely independent of the VCS, to ensure that ACC and towers can always communicate, whichever the status of the ordinary communication network between them. The new intercom connections put ACC and towers in direct connection, as if they were “hot lines”, not requiring an explicit acknowledgement when a call is received by the tower.

The intercom system is configurable by means of the supervision system already envisaged for the VCS, thus not requiring any further special configuration computer and also utilizing the same database to avoid any kind of mistake for error-free activities. Re-sectorizations made at VCS level automatically reflect at intercom level, without any need for manual intervention. The audio exchanged between operators over the intercom system is recorded, as it happens for any other communication for possible later analysis and replay.

Each ACC is equipped with a specially developed keyboard, capable of connecting up to 8 towers. Vice versa each connected tower is equipped with a receiving/transmitting device to manage intercom conversations to the relevant ACC. Loudspeakers make incoming audio audible at any time.
