AMENDED BY-LAWS OF GENERAL DATACOMM INDUSTRIES, INC. (A Delaware Corporation) As of July 22, 1999 ARTICLE I STOCKHOLDERS 1. CERTIFICATES REPRESENTING STOCK. Every holder of stock in the corporation shall be entitled to have a certificate signed by, or in the name of, the corporation by the Chairman or Vice-Chairman of the Board of Directors, if any, or by the President or a Vice-President and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary of the corporation certifying the number of shares owned by him in the corporation. If such certificate is countersigned by a transfer agent other than the corporation or its employee or by a registrar other than the corporation or its employee, any other signature on the certificate may be a facsimile. In case any officer, transfer agent, or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent, or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if he were such officer, transfer agent, or registrar at the date of issue. Whenever the corporation shall be authorized to issue more than one class of stock or more than one series of any class of stock, and whenever the corporation shall issue any shares of its stock as partly paid stock, the certificates representing shares of any such class or series or of any such partly paid stock shall set forth thereon the statements prescribed by the General Corporation Law. Any restrictions on the transfer or registration of transfer of any shares of stock of any class or series shall be noted conspicuously on the certificate representing such shares. The corporation may issue a new certificate of stock in place of any certificate theretofore issued by it, alleged to have been lost, stolen, or destroyed, and the Board of Directors may require the owner of any lost, stolen, or destroyed certificate, or his legal representative, to give the corporation a bond sufficient to indemnify the corporation against any claim that may be made against it on account of the alleged loss, theft, or destruction of any such certificate or the issuance of any such new certificate. 2. FRACTIONAL SHARE INTERESTS. The corporation may, but shall not be required to, issue fractions of a share. In lieu thereof it shall either pay in cash the fair value of fractions of a share, as determined by the Board of Directors, to those entitled thereto or issue scrip or fractional warrants in registered or bearer form over the manual or facsimile signature of an officer of the corporation or of its agent, exchangeable as therein provided for full shares, but such scrip or fractional warrants shall not entitle the holder to any rights of a stockholder except as therein provided. Such scrip or fractional warrants may be issued subject to the condition that the same shall become void if not exchanged for certificates representing full shares of stock before a specified date, or subject to the condition that the shares of stock for which such scrip or fractional warrants are exchangeable may be sold by the corporation and the proceeds thereof distributed to the holders of such scrip or fractional warrants, or subject to any other conditions which the Board of Directors may determine. 3. STOCK TRANSFERS. Upon compliance with provisions restricting the transfer or registration of transfer of shares of stock, if any, transfers or registration of transfers of shares of stock of the corporation shall be made only on the stock ledger of the corporation by the registered holder thereof, or by his attorney thereunto authorized by power of attorney duly executed and filed with the Secretary of the corporation or with a transfer agent or a registrar, if any, and on surrender of the certificate or certificates for such shares of stock properly endorsed and the payment of all taxes due thereon. 4. RECORD DATE FOR STOCKHOLDERS. For the purpose of determining the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or for the purpose of determining stockholders entitled to receive payment of any dividend or other distribution or the allotment of any rights, or entitled to exercise any rights in respect of any change, conversion, or exchange of stock, or for the purpose of any other lawful action, the directors may fix, in advance, a date as the record date for any such determination of stockholders. Such date shall not be more than sixty days nor less than ten days before the date of such meeting, nor more than sixty days prior to any other action. If no record date is fixed, the record date for the determination of stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto. When a determination of stockholders of record entitled to notice of or to vote at any meeting of stockholders has been made as provided in this paragraph, such determination shall apply to any adjournment thereof; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting. 5. MEANING OF CERTAIN TERMS. As used herein in respect of the right to notice of a meeting of stockholders or a waiver thereof or to participate or vote thereat, as the case may be, the term "share" or "shares" or "share of stock" or "shares of stock" or "stockholder" or "stockholders" refers to an outstanding share or shares of stock and to a holder or holders of record of outstanding shares of stock when the corporation is authorized to issue only one class of shares of stock, and said reference is also intended to include any outstanding share or shares of stock and any holder or holders of record of outstanding shares of stock of any class upon which or upon whom the certificate of incorporation confers such rights where there are two or 2 more classes or series of shares of stock or upon which or upon whom the General Corporation Law confers such rights notwithstanding that the certificate of incorporation may provide for more than one class or series of shares of stock, one or more of which are limited or denied such rights thereunder; provided, however, that no such right shall vest in the event of an increase or a decrease in the authorized number of shares of stock of any class or series which is otherwise denied voting rights under the provisions of the certificate of incorporation. 6. STOCKHOLDER MEETINGS. - TIME. The annual meeting shall be held on the date and at the time fixed, from time to time, by the directors. A special meeting shall be held on the date and at the time fixed by the directors. - PLACE.

The notice of an annual meeting shall state that the meeting is called for the election of directors and for the transaction of other business which may properly come before the meeting, and shall, (if any other action which could be taken at a special meeting is to be taken at such annual meeting) state the purpose or purposes. The notice of a special meeting shall in all instances state the purpose or purposes for which the meeting is called. If any action is proposed to be taken which would, if taken, entitle stockholders to receive payment for their shares of stock, the notice shall include a statement of that purpose and to that effect. Except as otherwise provided by the General Corporation Law, a copy of the notice of any meeting shall be given, personally or by mail, not less than ten days nor more than sixty days before the date of the meeting, unless the lapse of the prescribed period of time shall have been waived, and directed to each stockholder at his record address or at such other address which he may have furnished by request in writing to the Secretary of the corporation. Notice by mail shall be deemed to be given when deposited, with postage thereon prepaid, in the United States mail. If a meeting is adjourned to another time, not more than thirty days hence, and/or to another place, and if an announcement of the adjourned time and/or place is made at the meeting, it shall not be necessary to give notice of the adjourned meeting unless the directors, after adjournment, fix a new record date for the adjourned meeting. Notice need not be given to any stockholder who submits a written waiver of notice by him before or after the time stated therein. Attendance of a person at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends a meeting for the 3 express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver of notice. - STOCKHOLDER LIST. The officer who has charge of the stock ledger of the corporation shall prepare and make, at least ten days before every meeting of stockholders, a complete list of the stockholders, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten days prior to the meeting, either at a place within the city or other municipality or community where the meeting is to be held, which place shall be specified in the notice of the meeting, or if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

Every proxy must be signed by the stockholder or by his attorney-in-fact. No proxy shall be voted or acted upon after three years from its date unless such proxy provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and, if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the corporation generally. 4 - INSPECTORS AND JUDGES. The directors, in advance of any meeting, may, but need not, appoint one or more inspectors of election or judges of the vote, as the case may be, to act at the meeting or any adjournment thereof.

The number of directors may be fixed from time to time by action of a majority of the directors. The number of directors may be increased or decreased by action of the majority of the directors then in office. 3. ELECTION AND TERM. Any director may resign at any time upon written notice to the corporation. The Board of Directors shall consist of such number of persons fixed from time to time by the Board of Directors pursuant to resolution adopted by a majority of directors then in office. Subject to the rights of holders of any series of preferred stock, any vacancy in the Board of Directors caused by death, resignation, removal, retirement, disqualification or any other cause (including an increase in the number of directors) may be filled solely by resolution adopted by the affirmative vote of a majority of the directors then in office, whether or not such majority constitutes less than a quorum, or by a sole remaining director. Any new directors elected to fill a vacancy on the Board of Directors will serve for the remainder of the full term of that director for which the vacancy occurred. No decease in the size of the Board shall have effect of shortening the term of any incumbent director. 4. MEETINGS. - TIME.
