         This Current Report on Form 8-K/A is filed by Tollgrade Communications,
Inc. (the "Company") for the purpose of amending Item 7(a) and (b) of the
Company's Current Report on Form 8-K filed with the Securities Exchange

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS

         (a)      Financial Statements of Business Acquired.

         Based on a comparison of the most recent annual financial statements of
the acquired Cheetah business and the Company's most recent annual consolidated
financial statements, the acquired Cheetah business is not a "significant
subsidiary" (as defined in Section 210.1-02(w) of Regulation S-X) with respect
to which financial statements are required to be filed pursuant to Section
210.3-05 of Regulation S-X. Accordingly, financial statements for the acquired
Cheetah business are not required to be filed and will not be filed pursuant to
this Item.

         (b)      Pro Forma Financial Information.

         The acquisition of the Cheetah business did not meet any of the
conditions set forth in Article 11 of Regulation S-X with respect to which pro
forma financial information is required to be furnished. Accordingly, pro forma
financial information is not required to be filed and will not be filed pursuant
to this Item.

                                   SIGNATURES

         Pursuant to the requirements of the Securities Exchange Act of 1934,
the Registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.
