Press Release Summary = NetVanta 1335 Enhances All-In-One Integrated Platform with
802.11a/b/g and Layer 3 Switching

Press Release Body = HUNTSVILLE, Ala--May 22, 2007--ADTRAN(R), Inc. (NASDAQ: ADTN),
a leading supplier of networking equipment, today announced a new
performance-enhanced business-class Multiservice Access Router. The NetVanta 1335 is
a unique platform that integrates a modular IP access router, 802.11a/b/g Wireless
Access Point (WAP), 24-port Layer 2/3 Power over Ethernet (PoE) switch, firewall,
VPN appliance, and DSU/CSU, all in a single, compact chassis. The NetVanta 1335 also
features RapidRoute(TM) technology, delivering the enhanced performance necessary
for IP telephony, corporate connectivity and Internet access, with advanced services
like Quality of Service (QoS), Network Address Translation (NAT) and firewall
enabled.

\"The Tolly Group\'s initial spot check of the NetVanta 1335 shows that the integrated
platform packs diverse functionality into a single box, including routing, Layer 2/3
switching, VPN and firewall security and wireless access point capability - all of
the functions that are important to SMB and enterprise branch office users,\" said
Kevin Tolly, president/CEO/founder of The Tolly Group.

The NetVanta 1335 with Wi-Fi provides 802.11a/b/g dual radio support at speeds up to
54Mbps. It offers advanced business-class features including multiple SSIDs, the
ability to disable SSID broadcasts, 802.1x for user authentication, and WPA2
support. It also employs the concept of Virtual Access Points (VAPs), the equivalent
of wireless VLANs, that allow customers to securely segment their wireless network
just as they would their wired network.

\"As the need for instantaneous information continues to grow, so does the importance
of wireless connectivity,\" said Tim Saunders, vice president, product management,
ADTRAN Enterprise Networks Division. \"By adding Wi-Fi to our integrated platforms we
are increasing the number of applications this product will serve in the SMB space.
We continue to provide SMB customers with an all-in-one business solution that meets
their needs in terms of both functionality and price point.\"

This 1U-high platform offers a single expansion slot that can house any of the
NetVanta Network Interface Modules (NIMs) or Dial backup Interface Modules (DIMs).
For uplink or stacking capabilities, it also includes one or two Gigabit
SFP/1000Base-T Ethernet interface(s), dependent upon the model.

Like all NetVanta platforms, the NetVanta 1335 is based on the ADTRAN Operating
System (AOS). This allows for the support of standards-based switching and routing
functionality. The NetVanta 1335 provides 8.8 Gbps of non-blocking switching
capability at Layer 2 and Layer 3. It offers an integrated 24-port Fast Ethernet
switch, and includes a model that supports Power over Ethernet (PoE) functionality
on all 24 ports. The PoE variation of the NetVanta 1335 supports both the 802.3af
standard and pre-standard legacy functionality. Gigabit SFP/1000Base-T Ethernet
port(s) support stacking with the ability to stack and manage up to 16 switches from
a single IP address. QoS is used to prioritize mission-critical traffic like VoIP
and to control network traffic congestion on both the Local Area Network (LAN) and
Wide Area Network (WAN). Memory expansion is available via CompactFlash and can be
used for a variety of applications including backup and restoration of configuration
or data files.

For existing NetVanta-based networks, ADTRAN also announced the NetVanta 150
lightweight WAP. This business-class access point is perfect for corporate
environments that need a secure, integrated WLAN solution. The NetVanta 150 is
designed to exclusively co-exist with other NetVanta products and is centrally
managed through an ADTRAN Wi-Fi Access Controller integrated into various NetVanta
routers. Each of the Wi-Fi access controllers can manage up to eight NetVanta access
points.

The small form factor of the NetVanta 150 allows it to be placed in discrete
locations and it can be desktop or wall-mounted. In addition, the auto-sensing
10/100Base-T 802.3af compliant Ethernet port can be used to power the unit,
expanding installation options by eliminating the need to be near a power outlet.

The NetVanta 1335 and NetVanta 150 will be available at the end of May. List prices
are as follows: NetVanta 1335 $1,595; NetVanta 1335 with PoE $2,395; NetVanta 1335
with Wi-Fi $1,995; NetVanta 1335 with PoE and Wi-Fi $2,795; NetVanta 150 $425, ($445
with AC power supply).
