          TOLLGRADE ACQUIRES CHEETAH STATUS AND PERFORMANCE MONITORING
                           PRODUCT LINE FROM ACTERNA

PITTSBURGH, PA, February 13, 2003 -- Tollgrade Communications, Inc. (NASDAQ:
TLGD) today announced that it has purchased for $14.3 million in cash certain
assets and has assumed certain liabilities of the Cheetah(TM) status and
performance monitoring product line of Acterna, LLC. As part of the agreement,
contingent purchase consideration of up to $2.4 million may be payable in the
form of an earn-out based on certain 2003 performance targets for the acquired
business. Acterna has retained ownership of the Return Path segment of the
product line.

Tollgrade will offer jobs to 47 of the former Acterna employees, most of whom
are engineers and technicians. Tollgrade plans to consolidate the Cheetah status
and performance monitoring product with its LIGHTHOUSE(R) status monitoring
system. The product line will be based at Tollgrade's new facility in Sarasota,
Florida.

"As the cable industry continues to evolve, more service providers recognize the
need to proactively monitor power supplies and nodes in the cable broadband
access network," said Tollgrade CEO Chris Allison, "For many years, the Cheetah
name has been synonymous with cable status monitoring. By combining the Cheetah
tradition with the HMS compliance achieved by Tollgrade's LIGHTHOUSE system, we
have created a value proposition for large or small system operators, both here
and abroad."

Allison added, "Because the Cheetah product line is new to us, our management
team continues to evaluate its financial impact, as well as its subsequent
integration into the company, on our business as a whole. During the first
quarter of 2003, we will have owned the product line for roughly six weeks and
expect sales of $ 1.7 to $2.0 million for that period. Excluding any one-time
integration charges, our earnings goals for the new product line are breakeven
at the high end of the sales range. As it progresses, we expect the acquisition
to begin to become accretive to earnings during the second half of the year."

Parker/Hunter Incorporated acted as financial advisor to Tollgrade in connection
with this transaction.

FORWARD-LOOKING STATEMENTS
This release contains statements relating to future events that are considered
"forward-looking statements." These statements, which may be expressed in a
variety of ways, including the use of future or present tense language, relate
to, among other things, expected revenue and earnings results.

These forward-looking statements are based on assumptions that involve risks and
uncertainties and are subject to change based on the considerations described
below. The company does not undertake any obligation to publicly update any
forward-looking statements.



2



General economic conditions and the economic conditions of the
telecommunications industry, including the effect of negative line growth and
competition for the company's RBOC customers from wireless, cable providers and
other carriers entering the local telephone service market can affect the
capital budgets of the company's customers. If such conditions result in a
reduction of such budgets, the company's revenues can be adversely affected.

If the company's customers find themselves unable to meet their established
purchase forecasts and their own growth projections, such customers may curtail
their purchase of the company's products, which would adversely affect the
company's revenues.

If the company would be unable to establish customer or sales distribution or
OEM relationships relating to the new Cheetah business, it could affect the rate
of incoming orders, which would adversely affect sales and revenues.

If the financial strength of certain of the company's major customers should
deteriorate or such customers encounter difficulties in accessing capital, the
ability of such customers to purchase and pay for the company's products could
be impaired, with a corresponding adverse affect on the company's revenues.

If third parties with whom the company has entered into sales and marketing
partnerships should fail to meet their own performance objectives or (in some
cases) prove unable to continue to provide vendor financing to certain local
exchange carriers, customer demand for the company's products could be adversely
affected, which would have an adverse effect on the company's revenues.

Seasonal fluctuations in customer demand for the company's products can create
corresponding fluctuations in period to period revenues, and any increases in
the rate of order cancellation by customers could adversely affect future
revenues.

The carrying value of certain intangible assets, including goodwill, acquired by
the company from Lucent Technologies, Inc. ("Lucent") could be impaired if
changing market conditions indicate that lower than anticipated cash flows will
be produced by such intangible assets.

The final allocation of the purchase price will be completed following
acquisition of the Cheetah product line. This final allocation may differ from
that currently assumed, which may cause the amounts of any future amortization
to differ from current management estimates, resulting in an adverse affect on
the accompanying projected earnings.

If the company were to encounter a shortage of key manufacturing components from
limited sources of supply, or experience manufacturing delays caused by reduced
manufacturing capacity or integration issues related to the acquisition of the
Cheetah product line, loss of key assembly subcontractors or other factors, the
company's ability to produce and ship its manufactured products could be
adversely affected, with an adverse effect upon revenues.

The introduction of improved products or services or reduced prices by the
company's competitors could reduce the demand for the company's products and
services and adversely affect revenues.

If the company proves unable to respond effectively to technological change in
its industry, such as an evolution of the telephone network from circuit to
packet-based, by developing new products and services and obtaining customer
approval and acceptance of its products and services, demand for the company's
products and services could be adversely affected, which would adversely affect
revenues.

The company is dependent on a relatively narrow range of products and a small
number of large customers. As a result, the failure of one or a small number of
the company's products to gain or maintain acceptance in the marketplace, or the
decision by one or a few of the company's customers to curtail their purchases
of the company's products could have an adverse effect on revenues.

If one or more of a small number of key employees of the company were to cease
to be associated with the company, the company's future results could be
adversely affected.

If the company is unable to successfully assert and defend its proprietary
rights in the technology utilized in its products, its future results could be
adversely affected. If third parties were able to successfully assert that the
company's use of technology infringed upon the proprietary rights of others, the
future results of the company could be adversely affected.

If one or more of the company's products were to prove defective, the company's
relationships with its customers could be jeopardized and the company could be
subject to potential liability, adversely affecting the company's future
results.

If for any reason demand for the company's products should decrease
substantially, the company could find itself with excess inventory and obsolete
parts on hand, which could adversely affect future results. Changes in
government regulation, such as modification or repeal of The Telecommunications
Act of 1996, increasing the costs of doing business by the company or its
customers, or preventing the company or its customers from engaging in business
activities they may wish to conduct could adversely affect the company's future
results.
