New Devices Target Carrier Service Offerings for Small- and Medium-sized Business (SMB) Customers

HUNTSVILLE, Ala. --(September  19, 2006)--ADTRAN^®, Inc. (NASDAQ: ADTN), a leading global provider of networking and communications equipment, today announced the introduction of the NetVanta 3100 Series of fixed-port IP access routers. These devices are designed to address the needs of SMBs for secure cost-effective Internet access and corporate connectivity using carrier-supplied broadband services such as DSL or cable.

The NetVanta 3100 Series consists of the NetVanta 3120 and NetVanta 3130. The NetVanta 3120 is a fixed-port Ethernet router with an integral four-port managed Ethernet switch, a single 10/100Base-T Ethernet WAN interface, and an analog modem for dial-backup or remote management. The NetVanta 3130 is a fixed-port ADSL access router with an integral four-port managed Ethernet switch, a single ADSL WAN interface, and an analog modem for dial-backup or remote management. In addition to ADSL and ADSL2, the NetVanta 3130 supports today’s most advanced ADSL technology, ADSL2+, for applications with the ability to take advantage of its greater reach and higher bandwidth (up to 25Mbps).

Each of these devices offers a variety of standard features including:  standards-based routing/switching protocols; stateful inspection firewall for network security; IPSec VPN for secure corporate connectivity across the Internet; a familiar Command Line Interface (CLI) that eliminates re-training of technical personnel; a user-friendly Web-based Graphical User Interface (GUI); NAT-compatible SIP ALG for VoIP applications; Quality of Service (QoS) for VoIP and other delay-sensitive applications; and an analog dial-backup interface for disaster recovery/mission critical applications or for remote management by the carrier.

“The NetVanta 3100 Series addresses the needs of our carrier customers for cost-effective, business-class routers that offer proven reliability and remote management capability,” said Rick Schansman, senior vice president and general manager, ADTRAN Enterprise Networks Division. “SMBs benefit from versatile customer-premises devices that offer flexibility and security with a built-in switch, VPN for data protection, firewall for denial of service attacks, and dial backup for disaster recovery, all provided as a cost-effective, secure DSL/cable bundle from their carrier.”

The NetVanta 3120 and 3130 are priced at $595 and $645 respectively, and are currently shipping.
