      TELLABS DELIVERS NEXT-GENERATION VOICE/DATA SWITCH  
                   TECHNOLOGY TO SPRINT  

Lisle, Ill.-- Tellabs announced today that it will supply its AN2100
Gateway Exchange, a trademark of Tellabs Operations, Inc., system, a
next-generation voice/data switch, to Sprint under the terms of a new,
multi-year agreement valued at more than $100 million. 

The AN2100 system blends Tellabs' echo canceller and TITAN, a registered
trademark of Tellabs Operations, Inc., 5500 digital cross-connect
technology with packet and cell technologies to perform multimedia
adaptation and switching.  The system will allow Sprint to place
traditional, switched telephone services on its core ATM backbone, while
consolidating or eliminating legacy TDM network switching elements.
Tellabs and Sprint began to collaborate on the AN2100 feature set three
years ago.  

"The AN2100 system allows us to enable voice applications to be very
effectively integrated onto a broadband, distributed platform," said
Marty Kaplan, senior vice president and chief technology officer of
Sprint. "This is a significant step toward fully integrated voice and
data applications.  By collaborating closely with Tellabs, Sprint has
advanced to the next generation of switching equipment." 

"This announcement unveils a strategic Tellabs initiative to enable
voice telephone service over cell- and packet-based networks," said
Brian J. Jackman, Tellabs' president of Global Systems and Technology.
"The AN2100 Gateway Exchange system is the first of a series of new
Tellabs products designed specifically to enable our customers to
cost-effectively migrate from today's TDM world to future, cell-based
networks much like our industry-leading TITAN 5500 digital cross-connect
system helps customers migrate from asynchronous to SONET transmission."
