Unlike traditional architectures, the 1x1+1 ATA hardware and software designs fully utilize leading DSP resources and advanced patent-pending algorithms to eliminate the need for an additional RISC processor, significantly reducing the typical bill of material cost per unit. The solution is ideal for VoIP equipment suppliers desiring to add a low-cost, compact ATA solution to their portfolios. \t1x Telephone lines \t1x Ethernet port \t1x PSTN life-line port \tField Configurable The 1x1+1 ATA solution supports a telephone line, an Ethernet port, and a PSTN life-line port for automated voice service switching in case of a power outage or network disconnection and is stackable to larger port configurations. End users can connect their homes and businesses to VoIP services using conventional wired and cordless phones without incurring additional monthly service fees or adding extra hardware. The 1x1+1 ATA solution initiates calls using the rapidly emerging IP telephony standard Session Initiation Protocol (SIPv2) and supports multiple advanced codecs to optimize performance. For VoIP service providers looking for a design that is easily configurable with their networks, the solution provides secure and sophisticated Web-based provisioning and firmware update technology. The 1x1+1 ATA solution is reconfigurable in the field and designed to give OEMs and service providers the ability to bring their products to market quickly and deploy them with immediate interoperability in most broadband VoIP service provider networks. OEM customers can also take advantage of VOCAL's high-end customization capabilities, including reference design assistance and integration of value-added features.
