New NetVanta Platforms Bring Higher Density, Power Conservation and Lifetime Warranty

HUNTSVILLE, Ala--Aug. 25, 2008--ADTRAN(R), Inc., a leading supplier of voice and
data solutions for the Small and Medium-sized Business (SMB) market, today announced
a new array of NetVanta(R) switches designed to address a variety of SMB
applications and provide a wealth of new benefits including higher density, Gigabit
Power over Ethernet (PoE), power conservation, wireless controller capabilities and
a new limited lifetime warranty. These solutions are designed to address the need
for value-driven, business-class solutions in the SMB market and to provide a means
for SMBs to both upgrade and future-proof their Local Area Networks (LANs) as they
embrace architectures such as Gigabit-to-the-Desktop and Voice over IP (VoIP).

\"In an Internet economy, the competition is not just the business down the street or
across town, but anyone selling similar products or services online,\" according to
Naresh Singh, principal analyst, Networking and Communication Equipment, Gartner.
\"As a result, SMBs are being driven to become more enterprise-like in their network
architectures, while remaining on an SMB budget.\"

ADTRAN\'s NetVanta family of voice and data networking solutions was designed
specifically for this market and uniquely addresses the needs of the value-driven
SMB by providing a reliable, easy-to-use, business-class product at an SMB-friendly
price point. ADTRAN is introducing six new platforms to the award-winning NetVanta
family of switching solutions. These solutions ease the transition to
next-generation applications, while preparing SMB networks for future growth.

New innovative features being introduced in these platforms include the ability to
act as a Wi-Fi access controller, thus eliminating the need for a separate
controller; intelligent power conservation, which enables PoE units to conserve
energy by reducing power consumption; LLDP/LLDP MED, which simplify the deployment
and troubleshooting of IP phones on a VoIP network; cable diagnostics which
simplifies troubleshooting and repairs of the Ethernet cable plant/infrastructure;
and a limited lifetime warranty.
The new platforms include:

-- The NetVanta 1534 PoE - This is a managed, 26-port, Layer 2 Gigabit PoE switch.
This platform is perfect for higher-bandwidth applications and
Gigabit-to-the-desktop deployments and supports both 802.3af and legacy PoE. It
features CompactFlash and expandable RAM for easy configuration and backup.

-- The NetVanta 1534 - This model offers the same standard features as the NetVanta
1534 PoE, without PoE support.

-- The NetVanta 1238 PoE - This platform brings higher port density to the NetVanta
switch family. This 48-port, Layer 2 switch supports both 802.3af and legacy PoE
making it perfect for VoIP and Wi-Fi applications. It provides four Gigabit uplink
ports and allows SMB and branch office customers to future-proof their networks with
additional port count.

-- The NetVanta 1238 - This model offers the same standard features as the NetVanta
1238 PoE, but does not support PoE.

-- The NetVanta 1234 PoE - This 24-port Layer 2 Fast Ethernet Switch supports both
802.3af and legacy PoE making it perfect for VoIP and Wi-Fi applications. It offers
four Gigabit uplink ports and is ideal for SMBs with a need for fast, secure LAN
switching.

-- The NetVanta 1234 - This model offers the same standard features as the NetVanta
1234 PoE, but does not support PoE.

These platforms, like all NetVanta switching solutions, offer fast, secure,
cost-effective LAN switching and are based on the ADTRAN Operating System (OS). The
ADTRAN OS which is common across all NetVanta products and provides standards-based,
non-blocking switching; support for Virtual LANs (VLANs); Quality of Service (QoS),
Link Aggregation, advanced management; TCL scripting; and remote configuration
capability. They also feature a web-based Graphical User Interface (GUI) with
step-by-step configuration wizards, as well as a user-familiar Command Line
Interface (CLI) for ease of set-up and management.

These switching solutions complement ADTRAN\'s existing portfolio of NetVanta
routers, switches, IP business gateways, IP communications, wireless access and
security products, and together offer a complete networking solution for the
value-based SMB customer. All six NetVanta platforms will be available at the end of
August and have the following list prices:

NetVanta 1534 PoE $2,895

NetVanta 1534 $1,695

NetVanta 1238 PoE $2,195

NetVanta 1238 $995

NetVanta 1234 PoE $1,445

NetVanta 1234 $595

\"Today\'s SMB customers want real value. We understand that this is more than just a
price tag. It is a measure of factors such as reliability, performance and support,\"
said Tim Saunders, vice president of product management, ADTRAN Enterprise Networks
Division. \"ADTRAN\'s NetVanta products uniquely address each of these factors and
deliver a host of key benefits that make them the best value on the market for the
SMB or distributed enterprise.\"
