Exhibit 99.1

          ADC Provides Preliminary Estimates of Third Fiscal
              Quarter Results From Continuing Operations

    MINNEAPOLIS--(BUSINESS WIRE)--Aug. 9, 2004--ADC (Nasdaq:ADCT,
www.adc.com) today provided estimates of anticipated results from
continuing operations for the third fiscal quarter ended July 31,
2004. These preliminary estimates are provided in connection with
ADC's completion of the acquisition of the KRONE Group on May 18, 2004
and the divestiture of its Cuda(TM) cable modem termination system
product line, FastFlow(R) Broadband Provisioning Manager software
offering and Singl.eView(R) customer care and billing software
business. The Cuda and FastFlow divestitures were completed on June
29, 2004, and the closing of the Singl.eView divestiture is expected
to occur during ADC's fourth fiscal quarter ending October 31, 2004.
Third quarter results are expected to be reported on August 25, 2004
at approximately 4:00 p.m. Eastern time with a conference call
scheduled for 5:00 p.m. Eastern time.
    In the third fiscal quarter of 2004, the results of the Cuda,
FastFlow and Singl.eView product lines will be removed from continuing
operations and accounted for as discontinued operations. At this time,
ADC expects sales from continuing operations in the third quarter of
2004 to be around $235 million, GAAP loss per share from continuing
operations to be around $0.00 to $(0.01) and, after adjusting to
exclude restructuring charges, adjusted earnings per share from
continuing operations to be around breakeven. ADC's previous outlook
on May 19 did not give effect to these recently discontinued
operations, which had combined sales of approximately $22 million in
the second fiscal quarter of 2004. ADC's updated outlook for GAAP and
adjusted results includes estimates for intangible amortization
expense of approximately $2 million and integration expenses of
approximately $5 million, both as a result of the KRONE acquisition.
    "Since closing the KRONE acquisition in the third quarter, ADC and
KRONE employees have been able to meet to initiate detailed planning
for revenue synergies and cost reductions in the global business,"
said Robert E. Switz, president and CEO of ADC. "As we move into the
fourth quarter, we are beginning to implement these plans, which we
expect to have significant long-term benefits."
    A reconciliation of expected GAAP loss per share from continuing
operations to expected adjusted earnings per share from continuing
operations in the third quarter of 2004 follows. The ranges below
reflect current estimates for each item; however, ADC is still in the
process of completing its financial statements for the quarter and
actual results could vary from these estimates.



Net loss per share (GAAP) from continuing
 operations                                           $0.00 to $(0.01)


Adjustments for restructuring charges, impairment
 charges and certain non-operating gains/losses       $0.00 to $(0.01)
                                                      ----------------

Adjusted earnings per share from continuing
 operations                                           Around $0.00
                                                      ============


    Estimates of adjusted earnings per share from continuing
operations in this outlook exclude ADC's current estimates of
restructuring charges, impairment charges and certain non-operating
gains/losses that have been incurred as a result of restructuring
activities taken during the quarter. These estimates and actual
results depend on many factors, including the evolving outlook for
industry conditions and ADC's businesses, which result in a difference
between GAAP and adjusted earnings per share.
    On June 2, 2004, ADC filed a Form 8-K reporting the KRONE
acquisition with the Securities and Exchange Commission. Under SEC
rules, ADC is required to file an amendment to the 8-K report
containing historical stand-alone financial statements for the KRONE
Group and certain pro forma financial information for ADC reflecting
the acquisition. When ADC files this amendment, the following
financial information will be included:

    --  For ADC, pro forma combined income statements (unaudited)
        giving effect to the acquisition of KRONE and certain
        previously announced divestitures for the year ended October
        31, 2003 and the six months ended April 30, 2004, as well as a
        combined pro forma balance sheet (unaudited) as of April 30,
        2004. These divestitures consist of ADC's business related to
        the Cuda(TM) cable modem termination system product line, its
        operations related to the FastFlow(R) Broadband Provisioning
        Manager software and its business related to the
        Singl.eView(R) customer care and billing software.

    --  For KRONE, an audited income statement and cash flow statement
        for the year ended December 31, 2003; an audited balance sheet
        as of December 31, 2003; an unaudited income statement and
        cash flow statement for the three months ended March 31, 2004;
        and an unaudited balance sheet as of March 31, 2004.

    For several quarters, ADC has indicated that it has been
considering potential divestitures of certain product lines in its
portfolio. With the divestitures announced earlier this year, ADC is
nearing completion of this recent divestiture process with the
possibility of one additional divestiture of a product line not core
to its current strategy. With the KRONE acquisition, internal growth
initiatives and potential future additions, ADC remains focused on its
goal of growing profitably in its core network infrastructure business
and being a leader in each market served by the company.
    ADC cautions investors that providing preliminary estimates
remains extremely difficult and subject to change because of many
factors, including soft and changing industry conditions, acquisition
integration activities, as well as economic, geopolitical and other
uncertainties.
    ADC plans to discuss its third quarter 2004 results and current
outlook on a conference call scheduled for August 25, 2004 at 5:00
p.m. Eastern time. The conference call can be accessed by domestic
