6 May 2003 London and Madrid Lightwave-- Banverket, the Swedish carrier's carrier, is replacing its existing legacy backbone with DWDM equipment and an advanced bandwidth management system from Nortel Networks. In Madrid, Nortel's DWDM optical equipment and network management system will be used to interconnect universities and other institutions on the Research Telematics network.

The Banverket network is being built in response to growing demand for reliable 10-Gbit/sec channels and Gigabit Ethernet (GbE) services. This deployment, which is expected to be finished this month, is in addition to a framework supply agreement previously entered into between Nortel Networks and Banverket.

The Swedish carrier is deploying a multi-channel OPTera long haul DWDM network and OPTera Connect DX optical switches to replace the existing DWDM platform. The network will be managed through Nortel's Preside optical network management platform.

"We have chosen to install Nortel Networks equipment because of its proven reliability and efficient network management," said Lars Göran Bernland, chief technology officer, Banverket Telenät. "It will allow us to offer new, revenue-generating services such as Gigabit Ethernet to our carrier customers."

The new network can scale to 800 Gbits/sec. The OPTera Connect DX optical switch provides multi-ring interconnection at all SDH rates and multiple ring protection topologies, with the added ability to manage bandwidth between rings with VC-4 granularity. High-density optical interfaces from 155 Mbits/sec to 10 Gbits/sec, including GbE, maximize service capacity per square foot of floor space while minimizing power consumption and operational costs.

Banverket Telenät provides the railway sector with secure and high-quality telecommunication services for railway operations. It develops and manages the telecommunications installations of Banverket (the Swedish National Rail Administration), comprising some 13,000 km of fiber-optic cables network, which runs alongside the tracks of Sweden's railway system. In addition Banverket Telenät leases capacity on its transport and communications network to a market outside the railway sector. Banverket Telenät is, as a carrier's carrier, one of Sweden's largest suppliers of network capacity.

Separately, Nortel is supplying DWDM optical equipment to build the Research Telematics network of the Madrid Autonomous Region. The OPTera Metro 5200 multiservice platform is being deployed to interconnect universities located in the region with the National Institute of Aerospace Technique (INTA), the Superior Center for Scientific Research (CSIC) and the Internet.

The network is part of the RedIRIS (Interconexión de los Recursos InformáticoS) Network, Spain's national academic and research network. Currently about 250 institutions are connected to RedIRIS, mainly universities and research and development centers. Among the universities that are expected to be connected through the Research Telematics Network are: Universidad de Alcalá, Universidad Autónoma Madrid, Universidad Carlos III, Universidad Complutense de Madrid, Universidad Nacional de Educación a Distancia-UNED, Universidad Politécnica de Madrid and Universidad Rey Juan Carlos.

This new network will allow the different university and scientific communities established in the Madrid Autonomous Region to use new information and communication technologies. Services such as storage networking, videoconferencing, remote laboratories, grid computing, high-speed Internet access, and other broadband data and voice services will greatly enhance the environment for science and technology research in the region.

To implement this project, OPTera Metro 5200 and Preside optical network management will provide high-speed, broadband network services on an open, scalable optical transport platform. The system will be compatible with SDH, Fast Ethernet, Gigabit Ethernet, ESCON, FICON, Fibre Channel, and legacy asynchronous fiber optics systems (FOTS/PDH), independent of protocol and binary transmission speed and reaching data rates up to 10 Gbits/sec. OPTera Metro 5200 has a capacity of up to 32 protected wavelengths, or 64 unprotected, with each wavelength capable of carrying up to 10 Gbits/sec of information.

The Research Telematics Network is based on three independent fiber rings covering three main geographic areas in the region. The North ring, where the nodes of the Autónoma, Complutense, and Politécnica Universities of Madrid and UNED are located; the South ring where the Rey Juan Carlos and Carlos III universities are located; and the East ring, with the INTA nodes and University of Alcalá. The three rings converge at the central node of the CSIC, connected to the Iris Network. The ring topology protects each optical channel at the transport layer, providing resistance to failure in fiber sections or equipment line cards.
