 Item 2. Managements Discussion and Analysis of Financial Condition and Results of Operations
 The following discussion and analysis should be read in conjunction with Selected Financial
Data and our Consolidated Financial Statements and Notes thereto included in our Annual Report on
Form 10-K for the year ended September 30, 2005, as filed with the Securities and Exchange
Commission on December 14, 2005.
 Forward-looking Statements
 This
Quarterly Report on Form 10-Q/A contains statements that are not historical facts but are
forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and relate to such
matters as anticipated financial performance and involve known and unknown risks, uncertainties and
other factors that may cause our business or our industrys actual results, levels of activity,
performance or achievements to be materially different from those expressed or implied by any
forward-looking statements. Such statements include, in particular, statements about our plans,
strategies, prospects, changes and trends in our business and the markets in which we operate as
described in this Quarterly Report on Form 10-Q/A . In some cases, you can identify forward-looking
statements by terminology such as may, will, could, would, should, expect, plan,
anticipate, intend, believe, estimate, forecast, predict, propose, potential or
continue or the negative of those terms or other comparable terminology. These statements are
only predictions.
 These forward-looking statements include but are not limited to those identified in this
report with an asterisk (*) symbol. Actual results may differ materially from those discussed in
such forward-looking statements, and you should carefully review the cautionary statements set
forth in this Quarterly Report on Form 10-Q/A , including those set forth under the caption Risk
Factors in Item 1A of Part II of this report and those set forth in our Annual Report on Form 10-K
for the year ended September 30, 2005, as filed on December 14, 2005. We caution the reader,
however, that these factors may not be exhaustive.
 We may from time to time make additional written and oral forward-looking statements,
including statements contained in our filings with the Securities and Exchange Commission and in
our reports to stockholders. We do not undertake to update any forward-looking statements that may
be made in this Form 10-Q/A or from time to time by us or on our behalf.

   Conditions and Trends in Our Industry
   Summary of Our Financial Performance in the Second Quarter of Fiscal 2006
   
    
    In Japan, revenues decreased by 51% or $4.3 million from
the second quarter of fiscal 2005, primarily due to competition from
test products developed by two of our Japanese OEM customers, both for their own internal
use and for sale to our major Japanese telecom operator customers. We expect this
competitive factor to continue to impact our Japanese revenues for at least the remainder
of our current fiscal year. Revenues in Japan were also impacted by an 11% decrease in the
value of the yen, in which all our revenues in Japan are denominated.
    
    In regions outside Japan, our revenues continued to be affected
adversely by engineering delays. In the second quarter we received a further $2.7 million in orders requiring
additional engineering work on which no revenue could be recognized, bringing the cumulative
total of orders in this category to

$5.2 million at quarter end. We expect to begin
recognizing revenue on these orders in the fourth quarter of our
current fiscal year. In addition, other customer orders that we would
have expected to receive in the absence of engineering delays were
delayed or issued to other vendors.
 
    
    Our overall gross profit margin decreased by nine percentage points due to increases in
hardware component costs, services demonstration equipment costs and manufacturing overhead
as percentages of the related revenues.
    
    In the second quarter of fiscal 2006, we recorded $0.5 million in pre-tax, non-cash,
stock-based compensation expense under the newly applicable accounting standard, SFAS
123(R), Share-Based Payment.Because we elected to adopt this standard under the modified
prospective transition method, we did not restate prior periods to include stock-based
compensation expense. Refer to Stock-Based Compensation in the Critical Accounting
Policies and Estimates section below.

  Risks Related to Our Business
 Our quarterly operating results may fluctuate significantly, and this may result in volatility in
the market price of our common stock.
  
    
    the variable size and timing of individual purchases by our customers;
    
    absence of long-term customer purchase contracts;
    
    seasonal factors that may affect capital spending by customers, such as the varying
fiscal year ends of customers and the reduction in business during the summer months,
particularly in Europe;
    
    the relatively long sales cycles for our products;
    
    competitive conditions in our markets;
    
    exchange rate fluctuations;
    
    the timing of the introduction and market acceptance of new products or product
enhancements by us and by our customers, competitors and suppliers;
    
    costs associated with developing and introducing new products;
    
    product life cycles;

Our success depends on the timely development and introduction of new products.
  Historically, our revenues have been dependent upon a few significant customers, the loss of one
or more of which could significantly reduce our revenues.
  Our business is dependent on our customers outsourcing their telecommunications testing needs, and
our business could be harmed if the market for outsourced testing solutions declines or fails to
grow.
  If we do not effectively manage our growth, our business and operating results could be adversely
affected.

##### Table of Contents



We face foreign business, political and economic risks because a significant portion of our sales
is to customers outside the United States.
  
    
    longer customer payment cycles;
    
    greater difficulty in accounts receivable collection;
    
    difficulties in staffing and managing foreign operations;
    
    changes in regulatory requirements or in economic or trade policy;
    
    costs related to localizing products for foreign countries;
    
    potentially weaker protection for intellectual property in certain foreign countries;
    
    the burden of complying with a wide variety of foreign laws and practices, tariffs and
other trade barriers; and
    
    potentially adverse tax consequences, including restrictions on repatriation of
earnings.
  We face intense competition in our markets from more established test solutions providers, and if
we are unable to compete successfully we may not be able to maintain or grow our business.
  Our success depends on the continued growth of the telecommunications industry and increased use
of our test solutions, and lack of growth in this industry could harm our business.

Our business could be harmed if we were to lose the services of one or more members of our
senior management team, or if we are unable to attract and retain qualified personnel.
   We may not be able to achieve the anticipated benefits of any acquisitions we may make of other
companies, products or technologies.
  
    
    difficulties associated with assimilating the personnel and operations of acquired companies;
    
    potential disruption of our ongoing business;

  Many of our suppliers are sole source or single source suppliers, and our inability to obtain
adequate amounts of components from these suppliers could harm our business.

We depend on a limited number of independent manufacturers, which reduces our ability to control
our manufacturing process.
  The high level of complexity and integration of our products increases the risk of latent defects,
which could damage customer relationships and increase our costs.
  We face exposure to product liability claims, which if successful could harm our business.
  Our success is dependent on our ability to protect our intellectual property, and our failure to
protect our intellectual property could have a significant adverse impact on our business.

We could become subject to litigation regarding intellectual property, which could divert

  Environmental laws and regulations subject us to a number of risks and could result in significant

   Risks Related to Our Stock
 Our stock has been, and likely will continue to be, subject to substantial price and volume
fluctuations due to a number of factors, many of which will be beyond our control.
