MRS stays on track with Tellabs
Company builds first of its kind network for national railroad system in Brazil

Naperville, Ill. — MRS Logistica keeps the trains running on time in Brazil. In the mid-1990s the company started updating Brazil's railroad system. Now, to raise the system's volume and efficiency, MRS needs to modernize its communications network as well. MRS, one of Brazil's largest railway companies has 1,643 km of railways in a region that concentrates approximately 65% of Brazil's gross domestic product and is home to the largest industries in the country.

MRS chose Tellabs as the telecom technology partner to engineer its communications upgrade. Tellabs also will manage the migration to a centralized communications system that supports applications such as VOIP and video-conferencing.

Next stop: a brand new network
MRS is deploying the Tellabs® 8600 managed edge system and the Tellabs® 8100 managed access system. These products enable MRS to combine current and new traffic on a single converged network. MRS also will use the Tellabs® 8800 multiservice router for its unique virtual private LAN service capabilities. The network is the first of its kind in Brazil.

"This is a big project, and information technology will make the difference," said Decio Tomaz, chief information officer for MRS Logistica. "It's well known that the Tellabs 8600 system is the best you can get for its management and usage capabilities. With IP technology, we can do a lot of things that TDM (time division multiplexing) does not support."

Round trip ticket - equipment and services
MRS's core business is railroads, not telecom. It has a large number of trains, depots and offices spread all over the country. The project involved a deep analysis of the types of hardware and services MRS needed. So MRS turned to Tellabs for its high level of service and support, as well as network infrastructure.

Tellabs has operated in Brazil for over 10 years with network deployments that extend across the whole Brazilian geography. This presence in Brazil enables the company to be a full partner to MRS, with a deep knowledge of their business and market.

"Our environmental-hardened equipment can withstand the conditions of Brazil, and the management system puts MRS in control of the network," said Tarcisio Ribeiro, vice president of sales for Tellabs' Latin America and Caribbean region. "The flexibility of offering various interfaces for legacy and new services has been a key for MRS."

All aboard!
The upgraded MRS network provides reliable communications between operations centers and trains themselves. This centralized network management enables additional trains on the tracks, raises productivity and reduces fuel usage. So the people of Brazil, the environment and MRS all benefit from the new network.

From locomotive to caboose, Tellabs was the clear choice for MRS and Brazil.
