HUNTSVILLE, Ala, (August 23, 2007) - ADTRAN, Inc., (NASDAQ: ADTN) a leading supplier
of network equipment, today announced that it has been named as the Company of the
Year in the Network Infrastructure category in the Annual Report Card (ARC) from CMP
Channel\'s VARBusiness. Now in its 22nd year, the VARBusiness ARC Awards recognize
outstanding partner programs and superb vendor service in 15 product and service
categories including network infrastructure, mobile computers, mainstream business
servers, voice networking hardware, data and information management software, and
security appliances. The ARC awards were held at an awards ceremony August 21, at
the CMP Channel\'s XChange \'07 Conference in Orlando, Florida.

ADTRAN excelled beyond several industry-leading vendors to be named as Company of
the Year for Network infrastructure. The company received the highest marks of any
participant in two of the three subcategories in which it participated. Winners were
selected by VARBusiness editorial staff based on the survey results of more than
5,000 systems integrators, IT consulting organizations, value-added resellers
(VARs), solution providers and software developers.

\"We are pleased to be recognized by our partners as a preferred choice for their
business," said Ted Cole, vice president of channel sales, ADTRAN Enterprise
Networks Division. \"The ADTRAN ADvantage Partner Program continues to gain
recognition for excellence and this award further validates our position as one of
the leading channel programs in the networking industry."

\"Because vendors taking part in the VARBusiness Annual Report Card are selected by
their own Solution Provider partners, the Annual Report Card, over the last 22 years
has become the defining research on vendor/partner relationships," said Robert C.
Demarzo, vice president and editorial director, CMP Channel. \"We salute each of the
vendors named on this year\'s ARC.\"

The ADTRAN ADvantage Partner Program is designed to assist partners in achieving
their goals, while remaining flexible enough to match each partner\'s individual
business model and objectives. This program recognizes three tiers of participation:
ADvantage Plus, ADvantage, and Registered. Each tier provides a level of support and
reward that scales to the level of commitment the partner chooses. The foundation of
the program is ADTRAN\'s portfolio of innovative, reliable alternative networking
solutions designed especially for Small and Medium Businesses (SMBs) at price points
appropriate for the market.

Top priorities for the partner program include training, certifications and
product/technology specializations (Internetworking, IP Telephony); ease of doing
business; best-in-class pre- and post-sales technical support; clear points of
contact; demo programs; opportunity registration and lead generation.
In addition to this award, the ADTRAN ADvantage Partner Program has been recognized
as a five-star partner program by VARBusiness. ADTRAN Vice President of Channel
