    TELLABS ACQUIRES SONET PRODUCT LINE FROM TRANSYS NETWORKS INC.

    Broadened Tellabs' TITAN (a registered trademark of Tellabs Operations, 
    Inc.) Transport and Access Portfolio Will Speed SONET Deployment

    Lisle, Ill. -- Telecommunications equipment manufacturer Tellabs
    announced today that it has reached an agreement with TRANSYS Networks
    Inc., a privately held developer based in Montreal, Canada, to acquire
    SONET technology that complements Tellabs' TITAN line of SONET-based
    digital cross-connect systems.

    Under the terms of the agreement, Tellabs acquired TRANSYS Networks'
    SONET product line for a purchase price of approximately $17 million.

    "The TRANSYS SONET product line complements the capabilities of our
    TITAN 5300 and SONET-based TITAN 5500 digital cross-connect systems,"
    said Richard T. Taylor, vice president and general manager of the
    Tellabs Digital Systems Division.  "This family of products will become
    an integral part of our interoperable ring architecture."

    "These new TITAN network elements address the needs of a broadened
    SONET market that requires TITAN capabilities in a smaller, more
    affordable configuration," Taylor added.  "That's an enhancement to our
    portfolio that many customers are asking us to provide, and it positions
    us to more fully participate in the fast growing, multi-billion dollar
    market for SONET transport equipment."

    Tellabs expects to begin commercial trials and initial release of
    products based on the TRANSYS technology in the first half of 1997 with
    many feature enhancements to follow.

    "This acquisition is consistent with our strategy," said Tellabs
    Operations, Inc., President Brian J. Jackman.  "We are very impressed
    with the next-generation technology developed by this innovative
    Canadian company."

    TRANSYS President Elie Karam and his SONET development team will join
    Tellabs.  "We believe the synergy between the TRANSYS technology and
    Tellabs' industry-leading TITAN systems will result in a powerful
    broadband networking solution," Karam said.

    TRANSYS was founded in 1994, with the mission to design and develop
    innovative telecommunications infrastructure products.  The company's
    efforts have been directed toward the development of SONET networking
    equipment.

    Tellabs designs, manufactures, markets and services voice, data, and
    video transport and network access systems.  The company's products are
    used worldwide by the providers of communications services.  Tellabs,
    Inc., stock is listed on the Nasdaq Stock Market (TLAB).
