Tele2 Selects Tellabs Platform to Integrate High-Speed Data

                         Services Into
                               Existing Network

  LONDON, May 21 /PRNewswire-FirstCall/ -- Tele 2 Sverige AB, the leading
Swedish alternate telecommunications service provider, has chosen the next-generation synchronous digital hierarchy (SDH) platform from Tellabs to expand
its Internet and intranet services for enterprise customers.  Offering
Ethernet capabilities integrated into Tellabs' proven SDH solution, the
Tellabs(R) 6300 managed transport series will enable Tele2 to reduce costs,
quickly connect customers to Fast Ethernet and deliver high-speed data and
voice services. 
Tele2 is using the new Tellabs(R) 6350 switch node, a digital cross-connect with market-leading density, and the Tellabs(R) 6310 edge node for
access and customer premise applications.  Tellabs will also provide Tele2
with service support and customized training to enable rapid deployment and
help speed Tele2's time-to-revenue. 
"According to several analyst firms, Tellabs is leading the way in
providing next-generation SDH solutions that enable service providers to
implement high-speed Ethernet services over their SDH network," said Anders
Gustafsson, president of Tellabs International.  "This is the most
cost-efficient way to migrate an existing SDH network into a truly converged
network for transport of voice and data on the same infrastructure, which will
highly benefit our customers." 
The Tellabs 6300 managed transport series is the next generation of
Tellabs' carrier-class SDH platform.  The series enables network operators to
leverage their existing SDH investments and open up new revenue streams by
integrating optical Ethernet services into their installed base of SDH
transport equipment.  The modular units feature an extremely small footprint
combined with high functional density. 
Three products have been recently introduced into the next-generation
Tellabs 6300 series and are currently available: 

    -- The Tellabs(R) 6340 switch node, which is among the first products in
       the industry to offer Generic Framing Procedure (GFP), a standardized
       method of transporting Ethernet using SDH, enabling interoperability
       among equipment.  It is a multi-service provisioning platform (MSPP)
       that leverages an existing infrastructure to transport and deliver
       voice, high-speed data and video-on-demand services.
    -- The Tellabs 6310 edge node, which is a small and easy to use add/drop
       multiplexer with multiple applications for access and customer
       premises.  These applications include 2 Megabits per second (Mbit/s),
       34/45 Mbit/s, Fast Ethernet and ATM services.
    -- The scalable and high-density Tellabs 6350 switch node, which is a
       digital cross-connect with market-leading density that handles voice,
       leased line and value-added data services.  It enables network
       operators to generate new revenue streams and lower operating costs.

  All of the Tellabs 6300 managed transport system elements are monitored
and managed end-to-end from a single network management platform.
