Madrid, 24 May 2005 – Telvent (Nasdaq TLVT), the Global RealTime IT Company, has signed a contract with Valladolid City Council for the supply, installation, commissioning and five-year maintenance program for a Tetra (open digital trunked radio standard) radio communications network for the city of Valladolid in Spain. The project, which exceeds one million euros in contract value, will be funded on a rental basis.

Telvent technology will replace the current analog radio communications network and will provide radio communications services for local police force, firefighters and civil protection personnel. Telvent will supply a communications network composed of a main switching node (TNX-EL), three base stations, each with two carriers (seven communications channels and one control channel), as well as 467 portable terminals with GPS and 118 mobile terminals with GPS.

The Telvent Tetra Trunked System, TetraNode, is the only solution on the market with architecture and design based on nonproprietary state-of-the-art devices, with multi-protocol capacity (Tetra - Digital and MPT-1327-Analog), and soft-switch architecture, which offers users the flexibility required for integrating applications such as Vehicle and Person Location Systems (AVL), SCADA, emergency management centers, etc.

According to Manuel Sánchez Ortega, Telvent Chairman, “This new contract consolidates Telvent’s position in the Tetra digital radio communications market with a proprietary product, the ‘Telvent TetraNode’ Digital Trunked Radio Communications System, based on the Tetra standard.”

Telvent is a member of the Tetra MoU Association, which has as its main objective the development of products based on the Tetra standard. The Association is also focused on the integration and development of applications that increase the added value of the radio communications infrastructure.
