Addition of broadband 3G wireless capability in its NetVanta 3305 modular router.

New Capability Offers Customers Multiple Deployment Options at Broadband Speeds on Verizon Wireless' EV -DO Network


HUNTSVILLE, Ala. -(December 1, 2008) -ADTRAN, Inc. (NASDAQ: ADTN), a leading supplier of voice and data solutions, today announced the addition of broadband 3G wireless capability in its NetVanta 3305 modular router. The NetVanta 3G Network Interface Module (NIM) is certified for use with Verizon Wireless' BroadbandAccess Wireless Router service and provides a rapid, secure and cost -effective connectivity option when used in conjunction with ADTRAN's NetVanta 3305 modular router. The NetVanta 3G NIM provides Wireless Wide Area Network (WWAN) service using Verizon's Evolution Data Optimized Rev. A (EV -DO) service, allowing customers to take advantage of flexible deployment options at broadband speeds from a single platform.

The NetVanta 3305 router equipped with the NetVanta 3G NIM is ideal for a number of applications including use as a reliable network failover/backup option for large businesses or as a primary connection for smaller businesses. Used in a backup configuration, network traffic can be diverted to the 3G wireless connection in the event of a primary circuit failure, guaranteeing network connectivity. The NetVanta 3G NIM in the NetVanta 3305 router can also be used as a primary connection in applications requiring broadband speeds, rapid deployment or where wireline connections are not readily available.

"The ability to use the NetVanta 3G NIM for wireless service in conjunction with our Automatic Teller Machines (ATMs) has been a great asset to our bank," said Jeremy Carrigan, network administrator, Citizens National Bank. "The 3G NIM allowed us to service a highly congested tourist area that could not otherwise be accessed via wireline service and it performed flawlessly."

"We're delighted to be strengthening our relationship with ADTRAN," said Michael Schaefer, executive director -mobility solutions, Verizon. "The NetVanta 3G NIM's introduction will give existing NetVanta 3305 customers the ability to quickly and easily add 3G services with the simple addition of a NIM."

"The addition of 3G wireless capability to our NetVanta 3305 routers really adds to our options for backing up a failed circuit, in addition to being an attractive primary access selection for applications such as ATMs, lotteries, and kiosks," said Tim Saunders, vice president of Product Management, ADTRAN Enterprise Networks Division. "Now, both enterprise and Small and Medium Business (SMB) customers will benefit from the many advantages NetVanta products offer ranging from cost savings and reliability, to ease of use and support."

The NetVanta 3G NIM is designed for use with a wide range of NetVanta platforms and is currently certified for use in the NetVanta 3305 with Verizon Wireless in conjunction with its BroadbandAccess Wireless Router service. The NetVanta 3G NIM carries a list price of $795 while the NetVanta 3305 has a list price of $1,295. Both products are currently shipping. Verizon Wireless service plans are available through Verizon Wireless.
