SUPPLEMENT TO THE NOTICE OF ANNUAL MEETING OF SHAREHOLDERS
AND PROXY STATEMENT DATED JUNE 19, 2009 FOR THE
ANNUAL MEETING OF SHAREHOLDERS
TO BE HELD ON AUGUST 5, 2009

To the Shareholders of Tollgrade Communications, Inc.:

     The information contained in this Supplement (the “Supplement”) amends, supplements and, to the extent inconsistent, supersedes the corresponding information in the Notice of Annual Meeting of Shareholders and Proxy Statement dated June 19, 2009 (the “Proxy Statement”) previously sent to the shareholders of Tollgrade Communications, Inc., a Pennsylvania corporation (the “Company” or “Tollgrade”), in connection with the solicitation of proxies on behalf of the Board of Directors of Tollgrade for use at Tollgrade’s 2009 Annual Meeting of Shareholders (the “2009 Annual Meeting”) and at any adjournment or postponement thereof. The 2009 Annual Meeting will be held on Wednesday, August 5, 2009, at the Syria Shrine Center, 1877 Shriners Way, Cheswick, PA 15024, at 3:00 p.m., local time, which is the same place and time specified in the Proxy Statement. The Proxy Statement, together with Tollgrade’s WHITE proxy card, were mailed on or about June 22, 2009.

     The record date for the determination of shareholders who are entitled to notice of and to vote at the 2009 Annual Meeting, and at any adjournment or postponement thereof, is the close of business on May 8, 2009, which is the same record date specified in the Proxy Statement.

     A revised WHITE proxy card is enclosed with this Supplement. If you have not yet voted, please use the enclosed revised WHITE proxy card to vote as soon as possible. The only difference between the enclosed revised WHITE proxy card and the WHITE proxy card you previously received is the substitution of Charles E. Hoffman for Daniel P. Barry as a nominee for the Tollgrade Board. If you already returned, or hereafter return, the previously distributed form of WHITE proxy card before the 2009 Annual Meeting, your submitted WHITE proxy card will remain valid and will be voted at the 2009 Annual Meeting unless revoked, except that the proxies named thereon will use their discretionary authority to vote any shares you voted for Mr. Barry for Mr. Hoffman instead. Completing and returning the enclosed revised WHITE proxy card (naming Mr. Hoffman instead of Mr. Barry as a nominee) before the 2009 Annual Meeting will revoke any proxy previously submitted and the revised WHITE proxy card will be voted for the directors nominated by the Tollgrade Board as instructed on the form.

     All shareholders, regardless of whether they have previously submitted a WHITE proxy card, are urged to return the enclosed revised WHITE proxy card. Please discard any WHITE proxy card you may have previously received and use the revised WHITE proxy card enclosed with this Supplement. If you have already voted your shares, whether via online voting, by telephone or by returning the previously mailed WHITE proxy card, you may vote again by whichever method you choose and your later vote will supersede your earlier vote.

     This year’s annual meeting is particularly important and YOUR vote is extremely important. As you may be aware, affiliates of Ramius LLC (together with all affiliates and associates thereof, the “Ramius Group”) have filed definitive proxy materials with the Securities

and Exchange Commission to solicit proxies for the election at the 2009 Annual Meeting of three of their candidates to serve as directors of Tollgrade. Your Board of Directors has not approved or endorsed any of the Ramius Group’s nominees for election as director and strongly urges you NOT to sign or return any proxy card that the Ramius Group may send to you. Even a vote “AGAINST” the Ramius Group’s nominees on its proxy card will cancel any previously submitted WHITE proxy card. If you previously signed a proxy card sent to you by the Ramius Group, you can revoke that proxy and vote for your Board’s nominees at the 2009 Annual Meeting by completing and returning the enclosed revised WHITE proxy card. Only your latest dated proxy will count. Your Board of Directors unanimously recommends that you vote “FOR” all the Board’s nominees using the enclosed revised WHITE proxy card.

     This Supplement should be read in conjunction with the Proxy Statement. References to sections and subsections herein are references to the corresponding sections and subsections in the Proxy Statement and references to page numbers herein are references to page numbers in the Proxy Statement. Capitalized terms used in this Supplement that are not defined herein have the meanings given to them in the Proxy Statement.

     Except as specifically amended or supplemented by the information contained in this Supplement, all information set forth in the Proxy Statement remains accurate and should be considered in casting your vote by proxy or at the 2009 Annual Meeting.

     The date of this Supplement is July 7, 2009 and the date on which this Supplement and the accompanying form of revised WHITE proxy card will first be sent to Tollgrade shareholders is on or about July 7, 2009.

     Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Shareholders to be held on August 5, 2009. Under new rules issued by the Securities and Exchange Commission (the “SEC”), we are providing access to our proxy materials both by sending you a full set of proxy materials, including this Supplement, and by notifying you of the availability of our proxy materials on the Internet. Our proxy materials, including the Proxy Statement, this Supplement, and our Annual Report on Form 10-K for the fiscal year ended December 31, 2008 are available at http://www.tollgrade.com.

Why am I receiving this Supplement?

     In 2008, the Tollgrade Board of Directors (the “Tollgrade Board”) retained the investment banking firm of Needham & Company LLC to help it evaluate a range of strategic alternatives to enhance shareholder value. At the conclusion of this process, the Tollgrade Board determined that the most appropriate strategy to enhance value was to emphasize Tollgrade’s service assurance offerings to the telecom market and capitalize on the strength of its current customer relationships as it extended its capabilities to next generation architectures. Our refocused strategy, which involves the creation of new software offerings and partnerships, allows us to leverage our strong embedded base of customers, and enhance the value of our long term relationships and services agreements. Tollgrade also has the financial flexibility to execute on our refocused strategy, thanks to our strong balance sheet, which includes no debt and healthy cash reserves of more than $60 million.

     As part of the Tollgrade Board’s plan to transform Tollgrade and reinvigorate its global franchise, the Tollgrade Board was unanimous in its view that Tollgrade and all of its shareholders would benefit from the addition of independent directors with deep experience in the telecom sector. On May 13, 2009, the Tollgrade Board announced that, as part of its plan to enhance its telecom industry expertise through the addition of independent directors with deep experience in the telecom sector, it had retained CT Partners, a nationally-recognized executive

2

search firm, to assist it, in conducting a comprehensive search process to identify highly qualified and very experienced candidates with telecom industry expertise.

     Since the Proxy Statement and Tollgrade’s WHITE proxy card were mailed to shareholders, the Tollgrade Board has made significant progress on its plan to enhance its telecom industry expertise and, as a result of its comprehensive search process, has been able to identify and appoint two new highly qualified and very experienced independent directors with deep experience in the telecom sector who are committed to acting in the best interests of all shareholders.

     On June 24, 2009, the Tollgrade Board voted to increase its size from seven to eight members and unanimously appointed Edward H. Kennedy to fill the newly-created vacancy. Under the terms of Tollgrade’s Amended and Restated Bylaws, as most recently amended on May 21, 2007 (“Bylaws”), the Tollgrade Board may determine its own size so long as the size of the Tollgrade Board remains at not more than nine directors. In addition, under the terms of Tollgrade’s Amended and Restated Articles of Incorporation, as most recently amended on May 21, 2007 (“Articles”), if prior to Tollgrade’s 2010 Annual Meeting of Shareholders the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional director of any class elected to fill a vacancy resulting from an increase in such class shall hold office for a term that shall coincide with the remaining term of that class. Accordingly, the Tollgrade Board determined to appoint Mr. Kennedy to the class of directors whose term expires at the 2010 Annual Meeting of Shareholders which, prior to the appointment of Mr. Kennedy, had only two directors in that class. Pursuant to the Articles, the classification of the Tollgrade Board is in the process of being phased out. Beginning with the 2010 Annual Meeting of Shareholders, all directors will be required to stand for election annually.

     On July 6, 2009, the Tollgrade Board voted to further increase its size from eight to nine members until the final certification of the vote by shareholders at the 2009 Annual Meeting and unanimously appointed Charles E. Hoffman to fill the newly-created vacancy. To continue to maintain the number of directors in each class as nearly equal as possible, the Tollgrade Board determined to appoint Mr. Hoffman to one of the two classes of directors whose term expires at the 2009 Annual Meeting and whose members are required to stand for re-election at the 2009 Annual Meeting.

     In connection with his appointment to the Tollgrade Board, Mr. Hoffman has been nominated to stand for re-election at the 2009 Annual Meeting as a substitute nominee for Daniel P. Barry. Mr. Barry has served on the Tollgrade Board since 1995, served as Tollgrade’s Chairman of the Board from 2005-2009 and is one of the Tollgrade Board’s longest serving directors. Mr. Barry has informed the Tollgrade Board that he has determined not to stand for re-election so that he can retire from the Tollgrade Board following the 2009 Annual Meeting. Accordingly, immediately following the final certification of the voting results from the 2009 Annual Meeting, the size of the Tollgrade Board will be automatically reduced from nine to eight members.

     Mr. Hoffman has consented to being nominated for election to the Tollgrade Board, to being named in this Supplement and to serving as a member of the Tollgrade Board if elected by Tollgrade’s shareholders.

3

How has “Proposal No. 1 – Election of Directors” been amended?

     In light of the substitution of Mr. Hoffman as a nominee for election to the Tollgrade Board in place of Mr. Barry, Proposal No. 1, as set forth in the Proxy Statement, dated June 19, 2009, with respect to the 2009 Annual Meeting, is hereby amended to provide that the Tollgrade Board has nominated the following five (5) individuals to serve on the Tollgrade Board for a one-year term until the 2010 annual meeting of Tollgrade’s shareholders: Joseph A. Ferrara, Tollgrade’s Chairman and Chief Executive Officer, James J. Barnes, David S. Egan, Charles E. Hoffman and Brian C. Mullins.

     Unless otherwise instructed, the persons named in the accompanying revised WHITE proxy card will vote to elect Messrs. Barnes, Egan, Ferrara, Hoffman and Mullins to the Tollgrade Board, unless, by marking the appropriate space on the revised WHITE proxy card, the shareholder instructs that he, she or it withholds authority from the proxy holder to vote. The revised WHITE proxy card will not be voted for more than five candidates or for anyone other than the Tollgrade Board’s nominees or designated substitutes.

Procedural Matters

     A revised WHITE proxy card is enclosed with this Supplement. If you have not yet voted, please use the enclosed revised WHITE proxy card to vote as soon as possible.

Only your latest dated proxy will count. Your Board of Directors unanimously recommends that you vote “FOR” all the Board’s nominees using the enclosed revised WHITE proxy card.

Can I revoke my proxy or change my vote?

     Shareholders may revoke any previously delivered voting proxy at any time before it is voted at the 2009 Annual Meeting:

§	By delivering to our Corporate Secretary a signed written notice of revocation, bearing a date later than the date of the proxy, stating that the proxy is revoked;
§	By attending the meeting and voting in person (the shareholder’s attendance at the meeting will not, by itself, revoke the proxy – the shareholder must vote in person at the meeting to revoke a prior proxy);
§	By submitting a later-dated proxy card;
§	If the shareholder voted by telephone or the Internet, by voting at a later time by telephone or the Internet; or
§	If the shareholder has instructed a broker, bank or other nominee to vote the shareholder’s shares, by following the directions received from the broker, bank or other nominee to change those instructions.
