PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD MAY 6, 2008

We are providing this Proxy Statement to the stockholders of ADTRAN, Inc. in connection with the solicitation of proxies by our Board of Directors to be voted at the 2008 Annual Meeting of Stockholders and at any adjournments of that meeting. The Annual Meeting will be held at ADTRAN’s headquarters, 901 Explorer Boulevard, Huntsville, Alabama, on Tuesday, May 6, 2008, at 10:30 a.m., local time. The meeting will be held in the East Tower on the second floor. When used in this Proxy Statement, the terms “we,” “us,” “our” and “ADTRAN” refer to ADTRAN, Inc.

The approximate date on which this Proxy Statement and form of proxy card are first being sent or given to stockholders is April 3, 2008.

This Proxy Statement, the attached Notice of Annual Meeting and our 2007 Annual Report to Stockholders are available at www.proxyvote.com.

VOTING

General

The securities that can be voted at the Annual Meeting consist of our common stock, $.01 par value per share, with each share entitling its owner to one vote on each matter submitted to the stockholders. The record date for determining the holders of common stock who are entitled to receive notice of and to vote at the Annual Meeting is March 12, 2008. On the record date, 64,194,387 shares of common stock were outstanding and eligible to be voted at the Annual Meeting.

Quorum and Vote Required

The presence, in person or by proxy, of a majority of the outstanding shares of our common stock is necessary to constitute a quorum at the Annual Meeting. In counting the votes to determine whether a quorum exists at the Annual Meeting, we will use the proposal receiving the greatest number of all votes “for” or “against” and abstentions, including instructions to withhold authority to vote.

In voting with regard to the proposal to elect directors (Proposal 1), stockholders may vote in favor of all nominees, withhold their votes as to all nominees or withhold their votes as to specific nominees. The vote required to approve Proposal 1 is governed by Delaware law and is a plurality of the votes cast by the holders of shares represented and entitled to vote at the Annual Meeting, provided a quorum is present. As a result, in accordance with Delaware law, votes that are withheld will be counted in determining whether a quorum is present but will have no other effect on the election of directors.

In voting with regard to Proposal 2 to ratify the appointment of the independent registered public accounting firm, stockholders may vote in favor of the proposal or against the proposal or may abstain from voting. The vote required to approve Proposal 2 is governed by Delaware law and is the affirmative vote of the holders of a majority of the shares represented and entitled to vote on the proposal at the Annual Meeting, provided a quorum is present. As a result, abstentions will be considered in determining whether a quorum is present and the number of votes required to obtain the necessary majority vote for the proposal and, therefore, will have the same legal effect as voting against the proposal.

Under the rules of the national stock exchanges that govern most domestic stock brokerage firms, member firms that hold shares in street name for beneficial owners may, to the extent that those beneficial owners do not furnish voting instructions with respect to any or all proposals submitted for stockholder action, vote in their discretion upon proposals that are considered “discretionary” proposals under the rules of the exchanges. These votes by brokers are considered as votes cast in determining the outcome of any discretionary proposal. We believe

that Proposal 1 and Proposal 2 are discretionary. Member brokerage firms that have received no instructions from their clients as to “non-discretionary” proposals do not have discretion to vote on these proposals. If the brokerage firm returns a proxy card without voting on a non-discretionary proposal because it received no instructions, this is referred to as a “broker non-vote” on the proposal. “Broker non-votes” are considered in determining whether a quorum exists at the Annual Meeting, but “broker non-votes” are not considered as votes cast in determining the outcome of any proposal.

As of March 12, 2008, the record date for the Annual Meeting, our directors and executive officers beneficially owned or controlled approximately 1,562,788 shares of our common stock, constituting approximately 2.4% of the outstanding common stock. We believe that these holders will vote all of their shares of common stock in favor of each of the proposals.

Proxies

You should specify your choices with regard to each of the proposals (1) by telephone as directed on the enclosed proxy card, (2) over the Internet as directed on the enclosed proxy card, or (3) on the enclosed proxy card by signing, dating and returning it in the accompanying postage paid envelope. All properly executed proxy cards delivered by stockholders to ADTRAN in time to be voted at the Annual Meeting and not revoked will be voted at the Annual Meeting in accordance with the directions noted on the proxy card. In the absence of such instructions, the shares represented by a signed and dated proxy card will be voted “FOR” the election of all director nominees and “FOR” the ratification of the appointment of the independent registered public accounting firm. If any other matters properly come before the Annual Meeting, the persons named as proxies will vote upon those matters according to their judgment.

Any stockholder delivering a proxy has the power to revoke it at any time before it is voted by:

•

giving written notice to James E. Matthews, Secretary of ADTRAN, at 901 Explorer Boulevard, Huntsville, Alabama 35806 (for overnight delivery) or at P.O. Box 140000, Huntsville, Alabama 35814-4000 (for mail delivery);

•

executing and delivering to Mr. Matthews a proxy card bearing a later date;

•

voting again prior to the time at which the telephone and Internet voting facilities close by following the procedures applicable to those methods of voting, as directed on the enclosed proxy card; or

•

voting in person at the Annual Meeting.

Please note, however, that under the rules of the national stock exchanges, any beneficial owner of our common stock whose shares are held in street name by a member brokerage firm may revoke his proxy and vote his shares in person at the Annual Meeting only in accordance with applicable rules and procedures of the exchanges, as employed by the beneficial owner’s brokerage firm.

In addition to soliciting proxies through the mail, we may solicit proxies through our directors, officers and employees in person and by telephone or facsimile. We may also request that brokerage firms, nominees, custodians and fiduciaries forward proxy materials to the beneficial owners of shares held of record by them. We will pay all expenses incurred in connection with the solicitation of proxies.

The following table sets forth information regarding the beneficial ownership of our common stock as of January 31, 2008, by (1) each of our directors and our director emeritus, (2) each of our executive officers named in the Summary Compensation Table in this Proxy Statement and (3) all of our directors and executive officers as a group, based in each case on information furnished to us by these persons.

The Nominating and Corporate Governance Committee and the Board of Directors have determined that Messrs. Marks, Nair and Nichols and Dr. Huss, as well as director nominee Ross K.

Prior to each regularly scheduled Audit Committee meeting, these directors convene and hold a separate executive session as the independent directors of the Board. Mr. Nichols, our lead director, presides over these meetings.

Meetings of the Board of Directors and its Committees

All six of the incumbent directors, as well as director emeritus James North, attended the 2007 Annual Meeting of Stockholders on May 8, 2007.

The Audit Committee has been established in accordance with Section 3(a)(58)(A) of the Exchange Act. In connection with its responsibilities, the Board has delegated to the Audit Committee the authority to select and hire our independent registered public accounting firm and determine their fees and retention terms.

The Committee has authority to review and approve annual performance goals and objectives for our Chief Executive Officer, to evaluate his performance and to set his compensation based on the evaluation. The Committee is also responsible for reviewing and approving executive officers’ compensation and establishing performance goals related to their compensation within 90 days of the beginning of each fiscal year. The Committee oversees our benefit plans and evaluates any proposed new retirement or executive benefit plans. The Committee also advises the Board on trends in compensation programs for non-employee directors. The Compensation Committee has the authority to delegate its duties to subcommittees, but to date has not done so. In accordance with Delaware law, in November 2007 the Compensation Committee also delegated to the Chief Executive Officer the authority to determine the amount of the individual annual stock option grants to employees of ADTRAN that are not officers, subject to a maximum aggregate number of stock options approved by the Committee.

At the beginning of each calendar year, our Compensation Committee reviews the Management Incentive Bonus Plan results from the prior year, establishes the performance goals for the current year, approves any increases in executive salaries or other compensation, recommends plan changes, if any, for submission to our stockholders at the annual meeting, and approves the Compensation Committee’s report for our proxy statement. Mid-year the Compensation Committee generally reviews our compensation programs and makes recommendations to the Board regarding outside director compensation and, as necessary throughout the year, approves any equity grants and/or compensation for newly hired or promoted executives. Our Compensation Committee generally meets in the fourth quarter of each calendar year to determine and approve annual equity awards.

Our Compensation Committee generally receives proposals and information from our Chief Executive Officer for its consideration regarding executive and director compensation. Our Chief Executive Officer makes recommendations regarding salary increases, annual cash incentives and equity awards for all of our executive officers other than himself. In doing so, he consults with our Chief Financial Officer.

Our Compensation Committee has authority to retain and terminate any outside advisors, such as compensation consultants. In 2007, we did not engage a compensation consultant to assist in evaluating our compensation programs.

Compensation Committee Interlocks and Insider Participation

None of our executive officers or directors serves as a member of the board of directors or compensation committee of any entity that has one or more of its executive officers serving as a member of our Board of Directors or Compensation Committee.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is responsible for assisting the Board in identifying and attracting highly qualified individuals to serve as directors of ADTRAN, selecting director nominees and recommending them to the Board for election at annual meetings of stockholders. The Nominating and Corporate Governance Committee operates under a charter approved by the Board. The charter is posted on our website at www.adtran.com. The Nominating and Corporate Governance Committee is composed of H. Fenwick Huss, William L. Marks, Balan Nair and Roy J. Nichols, each of whom is independent under NASDAQ listing standards. Mr. Nair is the Chair of the Nominating and Corporate Governance Committee.

Consideration of Director Nominees

The Nominating and Corporate Governance Committee seeks to create a Board that is as a whole strong in its collective knowledge of, and diversity of skills and experience with respect to, accounting and finance, management and leadership, vision and strategy, business operations, business judgment, crisis management, risk assessment, industry knowledge, corporate governance and global markets. When the Committee reviews a potential new candidate, the Committee looks specifically at the candidate’s qualifications in light of the needs of the Board and ADTRAN at that time given the then current mix of director attributes.

In accordance with NASDAQ listing standards, we ensure that at least a majority of our Board is independent under the NASDAQ definition of independence, and that the members of the Board as a group maintain the requisite qualifications under NASDAQ listing standards for populating the Audit, Compensation and

Nominating and Corporate Governance Committees. The Board has adopted Corporate Governance Principles that set forth the principles that guide us and the Board on matters of corporate governance. The Corporate Governance Principles are posted on our website at www.adtran.com.

As provided in its charter, the Nominating and Corporate Governance Committee will consider nominations submitted by stockholders. To recommend a nominee, a stockholder should write to the Nominating and Corporate Governance Committee, care of James E. Matthews, Secretary of ADTRAN, at 901 Explorer Boulevard, Huntsville, Alabama 35806 (for overnight delivery) or at P.O. Box 140000, Huntsville, Alabama 35814-4000 (for mail delivery). Any recommendation must include:

•

the name and address of the candidate;

•

a brief biographical description, including his or her occupation for at least the last five years, and a statement of the qualifications of the candidate, taking into account the qualification requirements set forth above; and

•

the candidate’s signed consent to be named in the proxy statement if nominated and to serve as a director if elected.

To be considered by the Nominating and Corporate Governance Committee for nomination and inclusion in our proxy statement for the 2009 Annual Meeting, stockholder recommendations for director must be received by us no later than December 4, 2008. Once we receive the recommendation, we will deliver a questionnaire to the candidate that requests additional information about the candidate’s independence, qualifications and other information that would assist the Nominating and Corporate Governance Committee in evaluating the candidate, as well as certain information that must be disclosed about the candidate in the proxy statement, if nominated. Candidates must complete and return the questionnaire within the time frame provided to be considered for nomination by the Committee.

All of the current nominees for director recommended for election by the stockholders at the 2008 Annual Meeting are current members of the Board, except for Ross K. Ireland. In 2007, we hired Spencer Stuart, an executive and director search consulting firm, to assist in identifying and/or evaluating potential director nominees. Spencer Stuart identified Mr. Ireland as a nominee for director. In evaluating candidates for director, the Committee uses the qualifications described above, and evaluates stockholder candidates in the same manner as candidates from all other sources. Based on the Committee’s evaluation of each nominee’s satisfaction of the qualifications described above and, for incumbent directors, their prior performance as directors, the Committee determined to recommend Mr. Ireland for election and each incumbent director for re-election. The Committee has not received any nominations from stockholders for the 2008 Annual Meeting.

Communications with the Board of Directors

The Board has established a process for stockholders to communicate with members of the Board. If you have any concern, question or complaint regarding any accounting, auditing or internal controls matter, as well as any issues arising under our Code of Business Conduct and Ethics or other matters that you wish to communicate to ADTRAN’s Audit Committee or Board of Directors, you can reach the ADTRAN Board of Directors through our Corporate Governance Hotline by email at hotline@adtran.com, by mail at ADTRAN, Inc. Hotline, P.O. Box 5765, Huntsville, Alabama 35814, or by calling the hotline at 1-800-873-1110, extension 6600.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Overview and Philosophy

The goals of our executive compensation program are to:

•

provide competitive compensation that will help attract, retain and reward qualified executives, with a focus on talent from within the telecommunications industry;

•

align management’s interests with our success by making a portion of the executive’s compensation dependent upon corporate performance; and

•

align management’s interests with the interests of stockholders by including long-term equity incentives.

To achieve these goals, we focus on several key points in the design of our executive compensation program. First, retention is a very important consideration in our compensation programs, and internal promotion and retention of key executive talent has been a significant feature of our company. We believe that retention involves two interrelated components – establishment of a working environment that provides intangible benefits to our executives and encourages longevity and overall compensation that is generally competitive within our industry and among companies of comparable size and complexity. Augmenting compensation with a desirable working environment enables us to maintain an overall compensation program that generally provides roughly average overall compensation to our executive officers, as compared to companies with which we compete for talent, but still remain competitive. Our Compensation Committee has not historically employed compensation consultants to assist it in designing our compensation programs. Instead, we rely on our familiarity with the market and ongoing market intelligence, including occasional review of publicly available compensation information of other companies both those with which we compete and those within our geographic labor market, to gauge the competitiveness of our compensation programs. We do not, however, use any systematic process or designated group of companies for this review.

The Committee also seeks a compensation structure that is internally consistent and provides appropriate compensation for our executives in relation to one another. Consequently, the Compensation Committee does not focus on any particular benchmark to set executive compensation. Instead, we believe that a successful compensation program requires the application of judgment and subjective determinations based on the consideration of a number of factors. These factors include the following:

•

the scope and strategic impact of the executive officer’s responsibilities, including the importance of the job function to our business;

•

our past financial performance and future expectations;

•

the performance and experience of each individual;

•

past salary levels of each individual and of the officers as a group;

•

our need for someone in a particular position; and

•

for each executive officer, other than the Chief Executive Officer, the evaluations and recommendations of our Chief Executive Officer, in consultation with our Chief Financial Officer.

The Committee does not assign relative weights or rankings to these factors. Our allocation of compensation between cash and equity awards, our two principal forms of compensation, is based upon our historical practice and our evaluation of the cost of equity awards, as discussed in more detail below.

Our Chief Executive Officer works closely with the Committee to maintain an open dialogue regarding the Committee’s goals, progress towards achievement of those goals and expectations for future performance. The Chief Executive Officer updates the Committee regularly on results and compensation issues. Our Chief Executive Officer also provides the Committee, and in particular, the Committee Chair, with recommendations regarding

compensation for our executive officers other than himself. In part because the Chief Executive Officer works closely with the Committee throughout the year, the Committee is in a position to evaluate his performance and make its own determinations regarding appropriate levels of compensation for the Chief Executive Officer.

Tax Considerations

Section 162(m) of the Internal Revenue Code limits ADTRAN’s tax deduction for compensation over $1,000,000 paid to the Chief Executive Officer or to certain other executive officers. Compensation that meets the requirements for qualified performance-based compensation or certain other exceptions under the Internal Revenue Code is not included in this limit. Generally, the Compensation Committee desires to maintain the tax deductibility of compensation for executive officers to the extent it is feasible and consistent with the objectives of our compensation programs. To that end, our 2006 Employee Stock Incentive Plan and Management Incentive Bonus Plan were designed to meet the requirements so that grants and annual incentive bonuses under those plans will be performance-based compensation for Section 162(m) purposes. However, in the past, our executives’ compensation has not been high enough to make Section 162(m) a critical issue for ADTRAN. Therefore, deductibility under Section 162(m) is only one consideration in determining executive compensation, and the Compensation Committee may approve compensation that is not deductible in order to compensate executive officers in a manner consistent with performance and our need for executive talent.

Components of Executive Compensation

Our executive compensation program consists of base salary, commissions for sales executives, an annual incentive bonus program, and long-term equity incentives in the form of stock options. Executive officers also are eligible to participate in certain benefit programs that are generally available to all of our employees, such as medical insurance programs, life insurance programs and our 401(k) plan, and in a nonqualified deferred compensation program. The Compensation Committee of our Board of Directors oversees our executive compensation program.

Base Salary and Commissions. Base salaries are the most basic form of compensation and are integral to any competitive employment arrangement. At the beginning of each fiscal year, the Compensation Committee establishes an annual base salary for our executive officers as well as commission structures for our sales executives, based on recommendations made by our Chief Executive Officer, in consultation with our Chief Financial Officer. Consistent with our compensation objectives and philosophy described above, the Compensation Committee attempts to set base salary compensation, and adjust it when warranted, based on company financial performance, the individual’s position and responsibility within our company and performance in that position, the importance of the executive’s position to our business, and the compensation of other executive officers of ADTRAN with comparable qualifications, experience and responsibilities. The Committee also generally takes into account its perceived range of salaries of executive officers with comparable qualifications, experience and responsibilities at other companies with which we compete for executive talent. For our sales executives, commissions are an important element of cash compensation, because they tie the executive’s pay directly to his success in his area of responsibility. Our sales executives generally receive half of their cash compensation (not including annual incentive bonus payments, if any) in salary and half in commissions, which is consistent with our historical practice and our understanding of the standard practice in the market for these executives. The Committee also reviews historical salary and commission information for each of the executive officers as part of its analysis in setting base salaries and commission structures. The Committee uses this information to review historical progression of each executive officer’s compensation and to identify variations in compensation levels among the executive officers.

In January 2007, the Compensation Committee reviewed the base salaries of our executive officers, taking into account the considerations described above. The Committee approved salary increases for each of the named executive officers ranging from 3% to 6%, along with corresponding increases in the commission rates for Messrs. Fredrickson and Locke. The base salary increases for 2007 were as follows:


Named Executive Officer	2006 Base Salary		2007 Base Salary
Thomas R. Stanton	$	415,000	$	431,600
James E. Matthews	$	245,000	$	255,413
Raymond R. Schansman	$	208,000	$	220,480
Robert A. Fredrickson	$	209,000	$	215,270
P. Steven Locke	$	202,600	$	212,730

The standard increase in base salary throughout our company in 2007 was approximately 4%, with adjustments within each functional area based upon an individual’s relative performance and position within his or her area. This basic structure influenced the base salary increases for the named executive officers as well. For Messrs. Stanton and Matthews, their base salary increase reflected the standard increase throughout the company of approximately 4%. Mr. Schansman’s increase reflected his tenure with ADTRAN, his increased responsibility and the importance of his position to the organization following his promotion to Senior Vice President and General Manager of our Enterprise Networks division in late 2006. The increases for Messrs. Stanton, Matthews and Schansman also reflected their increased responsibilities in 2007, particularly as a result of the elimination of the chief operating officer position in early 2007.

Messrs. Fredrickson and Locke, both of whom are sales executives, received both base salary increases and corresponding increases in commission rates. For Mr. Fredrickson, his base salary and commission rate increase principally reflected the process used throughout the company, taking into account the overall percentage increase for his functional area and then adjusting for his position and the relative performance of his business unit with respect to overall corporate performance. In adjusting his base salary and commission level, the Committee also considered Mr. Frederickson’s historical base salary and commission rate with respect to other executives with similar positions within the company, resulting in a slightly lower increase than for the other named executive officers. For Mr. Locke, the Committee approved a base salary and commission rate increase that reflected his successful performance in the prior year as well as adjustments to align his salary and commission rate more closely with other executives with similar positions, resulting in a slightly higher percentage increase.

Annual Incentive Compensation. We provide annual bonuses under our Management Incentive Bonus Plan, which is designed to motivate and reward executives for their contribution to ADTRAN’s performance during the fiscal year. A significant portion of the total cash compensation that our executive officers could receive each year is paid through this program, and thus is dependent upon our corporate performance. Bonuses for 2007 were determined by a formula based on targeted per-share after tax earnings (“EPS”), as described in the narrative following the Summary Compensation Table and the Grants of Plan-Based Awards table. We use EPS as the performance measure for our annual incentive awards because we consider earnings growth to be the best indicator of stockholder value. The minimum EPS goal for 2007 was based on what we believed at the time to be an achievable level of growth, while at the same time a challenging one, substantially higher than the average growth rate of our EPS for the last few years. The Committee does not have the discretion under the Management Incentive Bonus Plan to award a bonus absent attainment of the minimum EPS goal. The Committee has the discretion to decrease a bonus payout under the plan even if performance measures are met, but does not have any discretion to increase a bonus payout. No bonuses were paid to our executive officers for 2007 because the minimum EPS required under the plan was not achieved. In addition, in 2007, the Committee did not exercise any discretion in its decisions regarding the plan.

For 2007, the Committee set the bonus targets for the Chief Executive Officer and Senior Vice Presidents, including Messrs. Stanton, Matthews and Schansman, at a minimum of 10% of base salary if the minimum targeted level of EPS were achieved, plus an additional 1% of base salary for each $0.01 of EPS above the minimum level. For Vice Presidents, including Messrs. Fredrickson and Locke, the corresponding initial bonus target was set at 5% of base salary, with an additional 0.5% of base salary for each $0.01 of EPS above the minimum level. The initial base salary target corresponded with the target set in the previous year, which the Committee believed remained appropriate in 2007. The Committee set a second target at 24% of base salary for the Chief Executive Officer and Senior Vice Presidents and 12% of base salary for Vice Presidents if a higher level of EPS were achieved, plus an additional 2% of base salary and 1% of base salary, respectively, for each $0.01 of EPS above the higher EPS level. The Committee set the EPS target for the second base salary target level based upon the EPS that would result from achievement of the high end of our internal corporate revenue goals. Because this EPS target was higher than the one used in previous years and therefore more difficult to achieve, the percentages of base salary corresponding to achievement of that level of EPS were increased for 2007. Our Management Incentive Bonus Plan is discussed further in the narrative following the Summary Compensation Table and the Grants of Plan-Based Award table below.

Long-Term Incentive Awards. We compensate our executive officers in part with annual grants of stock option awards under our 2006 Employee Stock Incentive Plan, which is described in the narrative following the Summary Compensation Table and the Grants of Plan-Based Awards table. We grant stock options every year because these awards are consistent with our compensation goals of aligning executives’ interests with that of our stockholders in the long term, and because these grants are a standard form of compensation among the companies with which we compete for executive talent. The Compensation Committee believes that stock option awards are an especially valuable tool in linking the personal interests of executives to those of our stockholders, because executives’ compensation under these awards is directly linked to our stock price. These awards give executive officers a significant, long-term interest in ADTRAN’s success. In addition, they can provide beneficial tax treatment that executives value due to the fact that we have typically granted incentive stock options to our executives to the maximum extent permitted under the tax laws. Moreover, the vesting component of our stock option awards provides a valuable retention tool, and retention is a significant consideration in making these awards.

Our option grants are timed to occur in the latter part of each year, to coincide with an open trading window under our insider trading policy. In November 2007, the Compensation Committee approved equity grants to our executives consisting solely of stock options that vest over a four year period, with 25% vesting on each anniversary of the grant date. Stock option grants in 2007 to the named executive officers are set forth in the Grants of Plan-Based Awards table below and described in the narrative below that table. In determining the amount of the option awards, the Compensation Committee began by deciding on an overall pool amount for the company, taking into account the estimated expense to us of the grants and the earnings per share impact of that expense. We typically establish an internal target for the aggregate expense from company-wide option grants, which we believe is at the low end of the expense levels incurred by our competitors. The Committee established a pool of up to 930,000 stock options for the 2007 annual grant, as compared to a pool of up to 879,827 stock options for the 2006 annual grant. The Committee then allocated the pool of options among the different functions throughout the company, based on the importance and performance of the function and considerations such as retention and competitive compensation levels. The Compensation Committee then set each executive’s individual award from the amount allocated to the function in which he serves, based on the recommendation of our Chief Executive Officer with input from our Chief Financial Officer. In determining the amount of the options grants for Messrs. Stanton, Matthews and Schansman, the Committee principally took into account their increased responsibilities in 2007, particularly as a result of the elimination of the chief operating officer position. Consequently, the Committee increased the option grants to these three officers in 2007. With respect to Messrs. Fredrickson and Locke, the Committee determined to increase their 2007 grant amounts in consideration of the fact that their grants in prior years had remained flat or had decreased, due to the need in those prior years for higher grants in other functional areas of the company to address retention concerns in those other areas.

Other Compensation. We maintain general broad-based employee benefit plans in which our executives participate, such as health insurance plans and a 401(k) plan. These benefits are provided as part of the basic conditions of employment for all of our employees, and therefore providing them to our executive officers does not represent a significant incremental cost to us. In addition, we believe that providing these basic benefits is necessary for us to attract talented executives. We also maintain a nonqualified deferred compensation plan, which is described under the Nonqualified Deferred Compensation table below. This plan permits executives to voluntarily defer a portion of their income and save money for retirement on a tax deferred basis. Although the plan permits discretionary employer contributions, to date we have not made any contributions to this plan. Therefore, this plan provides a benefit that executives value at virtually no cost to us.

As described in more detail under “Potential Payments Upon Termination or Change of Control” below, we provide limited benefits upon a change of control or upon termination of employment for specified reasons to participants, including the named executive officers, in our equity incentive plans and our Management Incentive Bonus Plan. All of these benefits are consistent with the basic benefits provided by the companies with which we compete for executive talent and help us to attract valuable executives. These benefits help to provide additional security that executives may need and reward loyal service in situations that create insecurity and present special challenges for executives. We provide the limited change of control benefits to encourage our executives to seek out and pursue business transactions that could be beneficial to ADTRAN and its stockholders.

Annual Incentive Awards

We provide our named executive officers with the opportunity to earn annual bonuses under our Management Incentive Bonus Plan. Under the bonus plan, within 90 days of the beginning of each year, our Compensation Committee establishes corporate goals to determine the eligibility for, and amount of, any annual incentive compensation for our executives. The Committee also determines the eligible individuals to receive awards and establishes the terms and conditions of all awards under the bonus plan.

In February 2007, our Compensation Committee established a formula to determine 2007 bonuses, based on a targeted level of per-share after tax earnings (“EPS”). If a minimum EPS target were achieved, each of Messrs. Stanton, Matthews and Schansman would have received a bonus equal to 10% of his base salary for the year, plus 1% of base salary for each $0.01 of EPS above the minimum EPS amount. Each of Messrs. Fredrickson and Locke would have received a bonus equal to 5% of his base salary (not including commissions) for the year, plus 0.5% of base salary for each $0.01 of EPS above the minimum EPS amount. If a second, higher EPS objective were achieved, each of Messrs. Stanton, Matthews and Schansman would have received a bonus equal to 24% of his base salary for the year, plus 2% of base salary for each $0.01 of EPS above the higher goal level. Each of Messrs. Fredrickson and Locke would have received a bonus equal to 12% of his base salary (not including commissions) for the year, plus 1% of base salary for each $0.01 of EPS above the higher goal level. The maximum potential bonus for each of Messrs. Stanton, Matthews and Schansman was 100% of his base salary for the year. The maximum potential bonus for each of Messrs. Fredrickson and Locke was 50% of his base salary for the year. No bonuses were paid to our executive officers for 2007 because the minimum EPS required under the plan was not achieved.

Equity Compensation

We granted stock options during 2007 to our named executive officers under the ADTRAN, Inc. 2006 Employee Stock Incentive Plan. The Stock Incentive Plan permits grants of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock and restricted stock units. Our Compensation Committee administers the Stock Incentive Plan, determines who will receive awards and establishes the terms and conditions of all awards.

The exercise price of the options we granted to our named executive officers during 2007 was equal to the fair market value of a share of our common stock on the date of grant. Fair market value is defined in the Stock Incentive Plan as the closing price of our common stock on the business day immediately before the date of grant. The option price may be paid in cash, in shares of our common stock, by broker-assisted cashless exercise, or by any other method permitted by the Committee.

The options we granted in 2007 to our named executive officers will become exercisable with respect to 25% of the shares on each of the first four anniversaries of the grant date. The options become immediately vested and exercisable upon the executive’s death or disability, and upon a change of control. The options may be exercised for one year after termination due to the executive’s death, disability or retirement, or for 90 days after termination for any other reason other than for cause, in which case the options immediately terminate. In addition, the Committee, in its discretion, may accelerate the vesting at any time. The provisions regarding acceleration of the options are described in more detail in the section on the Stock Incentive Plan below under the heading entitled “Potential Payments Upon Termination or Change of Control.”

Outstanding Equity Awards at 2007 Fiscal Year-End

(1)	This amount is included in the “Salary” column of the Summary Compensation Table for 2007 for Messrs. Stanton, Matthews, Fredrickson and Locke.

(2)	Includes an amount that is included in the “Salary” column of the Summary Compensation Table for 2006 for certain of the named executive officers, as follows: Mr. Stanton – $103,816; Mr. Matthews – $36,984; and Mr. Fredrickson – $52,250.

We maintain the ADTRAN Inc. Deferred Compensation Plan. This plan is offered as a supplement to our tax-qualified 401(k) plan and is available to our officers who have been duly elected by our Board of Directors. The deferred compensation plan allows participants to defer all or a portion of their salaries and annual bonuses, and permits us to make matching contributions on a discretionary basis, without the limitations that apply to the 401(k) plan. To date, we have not made any matching contributions under this plan. All contributions are unfunded and are credited to bookkeeping accounts for the participants, although we have set aside assets in a rabbi trust to help us

pay for the benefits under this plan. Each participant’s account is credited with earnings as if the account were invested as elected by the participant among pre-approved mutual funds. Benefits are usually distributed after termination of employment, or at age 65 if elected by the participant, in a single lump sum cash payment.

Potential Payments Upon Termination or Change of Control

This section describes the limited benefits that would be provided to our named executive officers under our executive compensation plans upon a change in control of ADTRAN or following termination of employment.

Management Incentive Bonus Plan

Under the ADTRAN, Inc. Management Incentive Bonus Plan, in the event of a change in control of ADTRAN, each executive will receive an immediate lump sum cash payment of the then-current annual incentive, but only if the performance measures set by the Compensation Committee for the relevant fiscal year have been attained as of the date of the change in control. The amount of the performance award would be consistent with the minimum, target or maximum level of performance measures actually achieved as of the change in control. Under the bonus plan, a change of control would occur if:

(1)

any person or group acquires more than 50% of the total fair market value or total voting power of our stock;

(2)

any person or group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) ownership of 35% or more of the total voting power of our stock;

(3)

a majority of our Board members is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board; or

(4)

any person or group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) at least 40% of the total gross fair market value of all of our assets.

If there had been a change of control of ADTRAN on December 31, 2007, none of our executive officers would have received a payment under this provision, because the minimum earnings per share target required under the 2007 performance measures had not been attained as of that date.

Deferred Compensation Plan

Under the ADTRAN Inc. Deferred Compensation Plan, participants are entitled to receive their benefits upon termination of employment. The amount they receive is based on their account balance, which would consist of their contributions to the plan and any earnings as described above in the Nonqualified Deferred Compensation table and its accompanying narrative. The Nonqualified Deferred Compensation table shows each executive’s account balance at the end of 2007, which is the amount each executive would have received if he had terminated employment on December 31, 2007.

2006 Employee Stock Incentive Plan

Under our 2006 Employee Stock Incentive Plan, the options we have granted will become immediately vested and exercisable upon the executive’s death or disability, or upon a change of control. Upon termination of employment for cause, all outstanding options immediately terminate. Options may be exercised for one year upon termination due to the executive’s death, disability or retirement, or for 90 days after termination for any reason other than cause.

Under the 2006 Employee Stock Incentive Plan, change of control is defined as:

(1)

the acquisition of beneficial ownership of 50% or more of either our outstanding shares of common stock or the combined voting power of our securities, except for any acquisition directly from us, any acquisition by us or our affiliates, or any acquisition by any of our employee benefit plans;

(2)

during any 12-month period, a majority of the Board is no longer composed of individuals who, as of the beginning of that period, constituted our Board and individuals whose nomination for election was approved by the Board;

(3)

a reorganization, merger or consolidation, where substantially all of the owners, respectively, of our outstanding shares of common stock or the combined voting power of our securities immediately before the transaction beneficially own less than 50% of, respectively, the common stock and the combined voting power of the securities of the resulting corporation, in substantially the same proportions as their ownership immediately prior to the transaction; or

(4)

the sale or other disposition of substantially all of our assets.

An executive is considered retired under the 2006 Employee Stock Incentive Plan if he terminates employment after age 65. Disability is defined as eligibility to receive long-term disability benefits or, if we do not have a long-term disability plan, an executive’s inability to engage in the essential functions of his or her duties due to a medically-determinable physical or mental impairment, illness or injury, which can be expected to result in death or to be of long-continued and indefinite duration. Cause means the executive’s willful and continued failure to perform his duties within 15 days of receipt of written demand for such performance; unlawful or willful misconduct which is economically injurious to us or our affiliates; conviction of, or a plea of guilty or nolo contendere to, a felony charge (other than a traffic violation); habitual drug or alcohol abuse that impairs the executive’s ability to perform his duties; embezzlement or fraud; competition with our business; or the executive’s breach of his employment contract, if any. Currently, none of our executives have employment contracts.

1996 Employees Incentive Stock Option Plan

Under our 1996 Employees Incentive Stock Option Plan, the options we have granted will become immediately vested and exercisable upon the executive’s death or disability, or upon a change of control. Upon termination of employment for cause, all outstanding options immediately terminate, unless the executive is terminated for cause after a change of control, in which case the options may be exercised for three months after termination. Options may be exercised for one year upon termination due to the executive’s disability, for one year upon the executive’s death, or for three months after termination for any reason other than cause.

Disability under the 1996 plan is determined by our Compensation Committee in its sole discretion. Change of control is defined as: (1) the acquisition by a person, group or entity of a sufficient number of shares of our common stock, or securities convertible into our common stock, to hold more than 50% of our common stock; or (2) any sale or other disposition of substantially all of our assets. Cause under the 1996 plan means acts by an executive that cause us liability or loss involving: personal dishonesty, incompetence, willful misconduct, moral turpitude, intentional failure to perform stated duties, willful violation of any law, rule or regulation (other than traffic violations or similar offenses), improper use or disclosure of our confidential information or trade secrets, the breach of any contract with ADTRAN, the unlawful trading in securities based on information gained through the performance of services for us, a felony conviction or the failure to contest prosecution for a felony, embezzlement, fraud, deceit or civil rights violations.

Because all of the outstanding unvested stock options held by the named executive officers as of December 31, 2007 under the 2006 Stock Incentive Plan and the 1996 Stock Option Plan had exercise prices higher than the closing price of our common stock on that date, Messrs. Stanton, Matthews, Fredrickson, Locke and Schansman would not have received any value on December 31, 2007 due to accelerated vesting upon a change of control or termination of employment due to death or disability.

The grant date fair value for the annual option award made to the directors in 2007 was $38,730, and the grant date fair value of the initial option award made to Mr. Nair upon his election to the board was $116,414. For a description of the assumptions used to determine the fair value of options recorded as expense in 2007 and the grant date fair value of options granted in 2007, see Note 2 to our Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2007, except that, as required by SEC regulations, the amounts included herein do not reflect any assumed forfeitures.

Name		Options
H. Fenwick Huss		55,000

William L. Marks		55,000

Balan Nair		15,000

Roy J. Nichols		59,000

James L. North		35,000

(5)	On April 16, 2007, the Board of Directors approved the acceleration and vesting of Mr. Blount’s outstanding unvested stock options.

Non-employee directors of ADTRAN, including Mr. North, our director emeritus, were paid an annual fee of $25,000, plus $1,500 for each Board meeting and $1,000 for each committee meeting attended in person and $500 for each Board or committee meeting attended by telephone, plus an annual retainer of $5,000 paid to each Board committee chairperson. In January 2008, the Board approved the payment of an annual fee of $10,000 to the director serving as lead director. This annual fee is in addition to all other fees received for services as a director or as a member or chairman of a committee of the Board. Directors who are employees of ADTRAN receive no directors’ fees. All directors are reimbursed for their reasonable expenses in connection with the performance of their duties.

Our non-employee directors, including our current director emeritus, are entitled to participate in our 2005 Directors Stock Option Plan, which our stockholders approved at the 2005 annual meeting of stockholders on May 18, 2005. As of December 31, 2007, there were a total of 400,000 shares reserved for issuance under the 2005 Directors Plan, of which 75,000 shares were subject to outstanding options and 320,000 shares were available for future option grants. The 2005 Directors Plan provides for automatic grants of nonqualified stock options to directors who are not otherwise employees of ADTRAN. As of December 31, 2007, there were four directors and one director emeritus eligible to participate in the 2005 Directors Plan. The 2005 Directors Plan is administered by the Compensation Committee. Subject to the terms of the 2005 Directors Plan, the Compensation Committee has the authority to determine the terms and provisions of the option agreements, to interpret the provisions of the 2005 Directors Plan, to prescribe, amend and rescind any rules and regulations relating to the 2005 Directors Plan, and to make all determinations necessary or advisable for the administration of the 2005 Directors Plan.

Under the terms of the 2005 Directors Plan, an eligible director is granted a nonqualified stock option to purchase 10,000 shares of common stock upon that director’s initial election to the Board, and receives an additional nonqualified stock option to purchase 5,000 shares of common stock as of December 31 of each subsequent calendar year in which the director is still serving as an eligible director. The options granted under the 2005 Directors Plan have a term of ten years, and the exercise price of the options is the fair market value of our common stock on the date of grant. The fair market value of our common stock under the 2005 Directors Plan is the closing price of a share of common stock on NASDAQ on the date of grant. The exercise price may be paid in cash, shares of common stock held for at least six months, or both, or by broker-assisted cashless exercise. The options generally vest on the first anniversary of the grant date; however, all non-vested options previously granted to an eligible director immediately vest upon that director becoming “disabled,” upon his death or upon a “change of control” of ADTRAN. Under the 2005 Directors Plan, “disability” means the total and permanent disability of an individual as determined by the Compensation Committee in its sole discretion. “Change of control” is defined as: (1) any acquisition of more than 50% of our common stock; or (2) any disposition of all or substantially all of our assets. Generally, unexercised options terminate three months after an optionee ceases serving as a director. However, the post-service exercise period is extended to a year after termination due to disability. Unexercised options terminate immediately if the director is terminated for “cause” prior to a change in control. Under the 2005 Directors Plan, “cause” is defined as an act or acts by an individual involving personal dishonesty, incompetence, willful misconduct, moral turpitude, intentional failure to perform stated duties, willful violation of any law, rule or regulation (other than traffic violations or similar offenses), the use for profit or disclosure to unauthorized persons of our confidential information or trade secrets, the breach of any contract with us, the unlawful trading in our securities or the securities of another corporation based on information gained as a result of the performance of services for us, a felony conviction or the failure to contest prosecution for a felony, embezzlement, fraud, deceit or civil rights violations, any of which acts cause us liability or loss, as determined by the Compensation Committee in its sole discretion. In addition, if a director dies during service, or during a period following termination of service when his options have not yet terminated as provided above, the director’s beneficiary can exercise the options for up to one year after the date of the director’s death. The options will not be exercisable past their expiration date, however, regardless of the reason for termination of the director’s service.

No options may be granted under the 2005 Directors Plan after May 18, 2015, ten years after its date of adoption. The 2005 Directors Plan will terminate on the later of (1) the complete exercise or lapse of the last outstanding option granted under the 2005 Directors Plan or (2) the last date upon which options may be granted under the 2005 Directors Plan, subject to its earlier termination by the Board at any time.

On December 31, 2007, in accordance with the terms of the 2005 Directors Plan, options exercisable for 5,000 shares of common stock were granted to each of Messrs. Marks, Nair, Nichols and North and Dr. Huss. In addition, Mr. Nair received a grant of options exercisable for 10,000 shares of common stock upon his election to the Board on May 8, 2007.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

James L. North, a partner in the law firm of James L. North & Associates, is our director emeritus and as of December 31, 2007, beneficially owned 101,000 shares of our common stock. We paid James L. North & Associates fees of $120,386 for legal services rendered to us during 2007. All bills for services provided by James L. North & Associates are reviewed and approved by our Chief Financial Officer. We believe that the fees for these services are reasonable and comparable to those charged by other firms for services rendered to us.

Policies and Procedures For Review and Approval of Related Person Transactions

We believe that business decisions and actions taken by our officers, directors and employees should be based on the best interests of ADTRAN, and must not be motivated by personal considerations or relationships. We attempt to analyze all transactions in which ADTRAN participates and in which a related person may have a direct or indirect material interest, both due to the potential for a conflict of interest and to determine whether disclosure of the transaction is required under applicable SEC rules and regulations.

Related persons include any of our directors or executive officers, certain of our stockholders and their immediate family members. A conflict of interest occurs when an individual’s private interest interferes, or appears to interfere, in any way with the interests of ADTRAN. Our Code of Business Conduct and Ethics requires all directors, officers and employees who may have a potential or apparent conflict of interest to fully disclose all the relevant facts to either a personnel supervisor, if applicable, or the Director of Internal Audit. Once a personnel supervisor receives notice of a conflict of interest he or she will report the relevant facts to the Director of Internal Audit. The Director of Internal Audit will then generally consult with the Audit Committee and a determination will be made as to whether the activity is permissible. A copy of our Code of Business Conduct and Ethics is available on our website at www.adtran.com under the links “Investor Relations – Corporate Governance – ADTRAN Code of Business Conduct and Ethics.”

In addition to the reporting requirements under the Code of Business Conduct and Ethics, each year our directors and officers complete Directors’ and Officers’ Questionnaires identifying any transactions with us in which the officer or director or their family members have an interest. A list is then maintained by us of all companies known to ADTRAN that are affiliated with a related person. Any potential transactions with such companies or other related party transactions are reviewed by the Chief Financial Officer and brought to the attention of the Audit Committee as appropriate. Our Audit Committee is responsible for reviewing and approving all material transactions with any related person.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act, and regulations of the SEC thereunder, require our directors, officers and persons who own more than 10% of our common stock, as well as certain affiliates of those persons, to file with the SEC initial reports of their ownership of our common stock and subsequent reports of changes in that ownership. Directors, officers and persons owning more than 10% of our common stock are required by SEC regulations to furnish us with copies of all Section 16(a) reports they file. Based solely on our review of the copies of these reports received by us and on information provided by the reporting persons, we believe that during the fiscal year ended December 31, 2007, our directors, officers and owners of more than 10% of our common stock complied with all applicable filing requirements, except that two stock option grant transactions for Michael K. Foliano, our Senior Vice President – Global Operations, were inadvertently reported late on a Form 4.

AUDIT COMMITTEE REPORT

The Audit Committee assists the Board of Directors in fulfilling its oversight responsibilities relating to the accuracy and integrity of ADTRAN’s financial reporting. In February 2004, our Board of Directors adopted an updated Audit Committee Charter, which sets forth the responsibilities of the Audit Committee. A copy of the Audit Committee Charter is available on our website at www.adtran.com.

The Audit Committee held 12 meetings during the fiscal year ended December 31, 2007. Representatives of PricewaterhouseCoopers LLP, our independent registered public accounting firm, attended each meeting. The Audit Committee reviewed and discussed with management and PricewaterhouseCoopers LLP our audited financial statements for the fiscal year ended December 31, 2007 and our unaudited quarterly financial statements for the quarters ended March 31, June 30 and September 30, 2007. The Audit Committee also discussed with PricewaterhouseCoopers LLP the matters required under Statement on Auditing Standards No. 61 and No. 90 (Codification of Statements on Auditing Standards, AU § 380), as amended or superseded.

In addition to the review of annual and interim financial statements, the Audit Committee continued its focus on functions and risks which could adversely impact ADTRAN’s financial position. Audit Committee meetings included overviews of the status of testing of key internal controls over financial reporting. The Audit Committee has actively reviewed management’s assessment of the effectiveness of ADTRAN’s internal control over financial reporting (including management’s evaluation of identified control deficiencies and management’s program for remediation of those deficiencies) and PricewaterhouseCoopers LLP’s report thereon, both of which are included in the Annual Report on Form 10-K for the year ended December 31, 2007.

The Audit Committee also received the written disclosures and the letter from PricewaterhouseCoopers LLP that are required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees) and has discussed with PricewaterhouseCoopers LLP its independence. The Audit Committee reviewed the audit and non-audit services provided by PricewaterhouseCoopers LLP for the fiscal year ended December 31, 2007 and determined to engage PricewaterhouseCoopers LLP as the independent registered public accounting firm of ADTRAN for the fiscal year ending December 31, 2008.

Based upon the Audit Committee’s review of the audited financial statements and the discussions noted above, the Audit Committee recommended that the Board of Directors include the audited financial statements in our Annual Report on Form 10-K for the year ended December 31, 2007 for filing with the SEC.

PROPOSAL 2 – RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

The Audit Committee of our Board of Directors, in accordance with its charter and authority delegated to it by the Board, has appointed the firm of PricewaterhouseCoopers LLP to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2008, and the Board of Directors has directed that such appointment be submitted to our stockholders for ratification at the Annual Meeting. PricewaterhouseCoopers LLP has served as our independent registered public accounting firm since 1986 and is considered by our Audit Committee to be well qualified. If the stockholders do not ratify the appointment of PricewaterhouseCoopers LLP, the Audit Committee will reconsider the appointment.

Representatives of PricewaterhouseCoopers LLP will be present at the Annual Meeting and will have an opportunity to make a statement if they desire to do so. They also will be available to respond to appropriate questions from stockholders.

The Audit Committee of the Board of Directors and the Board unanimously recommend that the stockholders vote “FOR” the proposal to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of the Independent Registered Public Accounting Firm

The Audit Committee has adopted a pre-approval policy that provides guidelines for the audit, audit-related, tax and other non-audit services that may be provided to us by PricewaterhouseCoopers LLP. The policy: (1) identifies the guiding principles that must be considered by the Audit Committee in approving services to ensure that PricewaterhouseCoopers LLP’s independence is not impaired; (2) describes the audit, audit-related, tax and other services that may be provided and the non-audit services that may not be performed; and (3) sets forth pre-approval requirements for all permitted services.

Under the policy, a schedule is presented annually to the Audit Committee outlining the types of services that are likely to be performed during the year. The Audit Committee, based upon the guidelines in the policy, selects the services from that schedule that will be generally pre-approved and attaches the list of services as an appendix to the policy. The Audit Committee then sets an annual aggregate fee limitation for all of the generally pre-approved services. For fiscal year 2007, that limit was set at $50,000. Any fees for the generally pre-approved services that exceed this aggregate fee limit must be specifically pre-approved. In addition, any services not on the list of general pre-approved services must be specifically pre-approved.

Each member of the Audit Committee has been delegated the authority to provide any necessary specific pre-approval, in the event that the full Audit Committee is not available. Any member of the Audit Committee who provides specific pre-approval must report such approval to the Audit Committee at its next meeting. To ensure compliance with the policy, a detailed report outlining all fees incurred year-to-date for services provided by PricewaterhouseCoopers LLP is presented to the Audit Committee on a quarterly basis.
