January 16, 2001 -- ADTRAN, a provider of DSL deployment equipment, and TollBridge Technologies, a developer of voice-over-broadband solutions for broadband carriers, announced that ADTRAN's Total Access product line of Integrated Access Devices (IAD) has completed certification testing requirements with the TollBridge TB200 voice gateway. The companies say that completion of these tests means that telecommunications service providers, such as CLECs, ILECs, and ISPs, can now provide integrated voice and data services and achieve high levels of voice quality while maintaining the integrity of existing network infrastructure.

According to the companies, certification of ADTRAN's Total Access IADs with the TollBridge TB200 broadband voice gateway enables small and medium sized businesses to deploy VoT1 and VoDSL solutions with the assurance that toll-quality voice levels will be met. TollBridge's testing procedures included TR-57 Compliance, Bulk Call Generation, and Voice and Data Quality of Service (QoS). The ADTRAN Total Access product line has TR-57-compliant analog voice interfaces that assure toll-quality voice over IP networks. And QoS parameters can guarantee the priority of voice calls without any degradation of voice quality on converged voice and data circuits.
