ULISES G5000iVoIP Communications Gateway

Based on international standards for air traffic control, the ULISES G5000i acts as a bridge between Voice over IP (VoIP) and analogue/digital systems, handling legacy and VoIP radio and telephony units. It is used for both civilian and military voice communications.

Integral solution for communication networks

ULISES G5000i is responsible for converting the protocol of aeronautical data and communication network elements (radio, telephony, etc.), allowing an efficient migration to IP: sustainable and scalable investment at a reduced cost and multiple supported interfaces. The system design meets the ED137 standard, allowing interoperability with units produced by multiple vendors.

Reduced cost: simple and sustainable migration

• Protocol conversion makes operation with multiple legacy interfaces possible, meaning that the replacement of network equipment is not required.

• Radio and telephony interfaces are managed by a single board, facilitating the installation and configuration of a sustainable solution.

• Reduced hardware investment: the large processing capacity of the boards means that investments in hardware acquisition are kept to a minimum. Up to 48 channels in a single rack.

• Guaranteed support for a 10-year period.

Optimisation of the amortisation and life cycles of all radio and telephony equipment already installed.

Encrypted communicationsOptimal network performance

Network performance will benefit from three key aspects:

• Availability: extremely high gateway availability (up to 99.999%) with hardware redundancy and hot-pluggable mechanisms. The redundant Ethernet network with a virtual IP guarantees system continuity if one of the main elements is down.

• Shared resources: ability to remotely control and manage all radio and telephony units on the network.

• Efficient management and maintenance: local or remote management and maintenance through a user-friendly and intuitive graphical user interface.

Through DF Epicom (a reference company in Spain for data encryption), the solution can include encrypted communications up to the highest possible level of NATO certification, with algorithm customisation capabilities.

DF Núcleo is currently implementing VoIP communication gateways for the Air Navigation Data Network (REDAN) throughout Spain. Winning this contract has helped to strengthen the leadership position of the Duro Felguera subsidiary in the field of domestic and international aeronautical communications.

On this occasion, the ULISES G5000i product will be installed at 98 sites: 5 control centres (ACC) and 38 control towers, as well as at multiple Spanish Air Force bases and communications centres distributed throughout the country.
