ADTRAN Unveils Innovative Voice Quality Monitoring Technology in NetVanta and Total
Access VoIP Platforms

Graphical User Interface Eases Monitoring and Management of VoIP Traffic

HUNTSVILLE, Ala.-(April 14, 2008)-ADTRAN®, Inc. (NASDAQ: ADTN), a leading supplier
of innovative networking and communications equipment today announced the
availability of Voice Quality Monitoring (VQM) as part of the ADTRAN Operating
System (AOS). Products that will support VQM include: NetVanta® Routers, NetVanta
IP Business Gateways and Total Access® 900 Series IP Business Gateways. ADTRAN's
unique VQM suite allows network administrators or carriers to examine the data
stream and identify problems, via an intuitive, graphic interface. Unlike other
implementations, ADTRAN's graphics-based approach presents findings in an
easy-to-use manner that significantly reduces the time devoted to identifying and
troubleshooting voice problems. This allows for a rapid return to a high-quality
service experience for Voice over IP (VoIP) users.


ADTRAN's VQM is unique in that it provides a graphical interface that allows network
administrators to view both active and historical VoIP call statistics. The
easy-to-read analytical charts and graphs allow service providers and administrators
to assess overall network health quickly and easily. It also allows them the ability
to closely examine areas with less than optimal call quality with the click of a
mouse. VQM looks at the most important aspects of voice calls: Mean Opinion Score
(MOS), delay, jitter and dropped or out-of-order packets. Administrators have the
ability to perform data searches by any given parameter, including date, day, time,
extension, VLAN, IP address, among others. Multi-term searches are even more
powerful and allow administrators to pinpoint specific data by combining search
terms such as searching for traffic on a specific extension on a specific day in a
specific time range. This greatly expedites troubleshooting and problem resolution
by reducing the amount of time spent parsing through unwanted or unneeded data.

"As midmarket customers embrace IPT, there is an increasing need for simple,
integrated toolsets to drive quality and repeatability in the VoIP environment.
These tools should offer reporting, trending and call-by-call visibility to allow
for rapid trouble isolation and fine-grained optimization," said Robert Mason,
principal research analyst, Gartner.

"Our approach to VQM stems from our desire to make ADTRAN platforms the easiest on
the market to install and manage," said Tim Saunders, vice president of product
management, ADTRAN Enterprise Networks Division. "When users experience poor voice
quality, most don't know what type of problem they are experiencing; they just know
it sounds bad. Our VQM implementation allows network administrators to quickly
identify the problem(s) and investigate the source of the trouble quickly and easily
via a non-invasive graphical interface."

VQM is currently available as part of the AOS at no additional charge. Platforms
