ADTRAN, Inc. (Nasdaq:ADTN), the market leader in Integrated Access Devices (IADs) and G.shdsl technology, today introduced three new IADs in its Total Access(TM) System of distributed access solutions. Ideal for Voice over DSL (VoDSL) applications, the new Total Access IADs support both TDM and ATM networks with cost effective, fixed port configurations. These Carrier Class devices support voice-only or converged voice/data solutions, providing small-to-medium-sized enterprises and integrated communications providers, such as CLECs, ILECs, and ISPs, a means to offer combined voice and data traffic over a single network interface.

The new Total Access IADs include network interface ports for T1, SDSL, or G.shdsl and are compatible with industry leading DSLAMs and voice gateways for quick turn-up of VoDSL or VoATM services. These devices are also ideal for many enterprise TDM applications.

As components of the Total Access System, the Total Access 604 provides four fixed analog voice interfaces, while the Total Access 608 provides eight fixed analog voice interfaces. These analog FXS interfaces support the stringent design and full feature set required by today's carriers. Both products provide a built-in IP router and an integrated V.35 port for synchronous data applications, allowing the customer to combine a variety of voice and data services into a single platform. The Total Access 544 offers four ISDN interfaces accompanied by a V.35 port for synchronous data applications as well as an IP router. The Total Access 604 and 608 are designed for domestic use, while the Total Access 544, with ISDN S0 ports, is designed for international applications. Compact yet durable, Total Access IADs are housed in rugged, metal enclosures. They provide additional security with a battery back-up system.

"The VoDSL and VoATM implementations found in the Total Access IADs are compatible with industry leading voice gateways such as CopperCom, Jetstream, Tdsoft, and TollBridge," said Tim Saunders, ADTRAN's vice president of product management, Enterprise Networks Division. "The Total Access 544 extends ADTRAN's VoDSL product offering to the international marketplace by offering an ISDN voice solution for Europe."

ADTRAN's Total Access products feature cutting-edge G.shdsl technology. An international standard leading to multi-vendor interoperability, G.shdsl (ITU G.991.2) is expected to be approved in February 2001. G.shdsl is a symmetric, multirate DSL offering greater rates with greater reach and spectral compatibility, making it easier to deploy than previous technologies. Service providers are expected to deploy G.shdsl to provide optimal VoDSL service delivery for small-to-medium-sized enterprises.

"The approval of G.shdsl in February will make it a true standard for worldwide deployment," said Everett Brooks, DSL product line manager for ADTRAN. "G.shdsl will be an ideal end-to-end deployment solution for applications that require high-speed, symmetric multirate DSL service across a single pair of copper wires. G.shdsl is a perfect deployment solution for voice over broadband and VoDSL."

These IADs are the newest additions to ADTRAN's Total Access System of broadband and narrowband access platforms, the industry's most flexible solution for deploying the latest loop technologies.
