With millions of small- to medium-sized enterprises existing today, the requirement for carriers to provide integrated voice and data solutions is growing at a rapid rate. ADTRAN delivers with Total Access Integrated Access Devices (IADs). The Total Access 612, 616, and 624 are three cost-effective, fixed-port, IADs designed to support either TDM or emerging packet architectures. These IADs offer enterprise users and integrated communications providers, such as CLECs, ILECs, and ISPs, a means to offer combined voice and data traffic over a single network interface terminating at the customer's premises. The Total Access 624 provides a full 24-port voice capacity for large voice applications. These analog FXS interfaces support the stringent design and full feature set required by today's carriers. Total Access 600 series IADs provide a built-in IP router and Nx56/64 V.35 port for synchronous data applications, allowing the customer to combine a broad variety of voice and data services into a single platform. Total Access IADs are compatible with industry-leading DSLAMs and voice gateways for VoATM and VoDSL applications. The FXS interfaces support all popular CLASS features, and an additional Assured Dialtone analog interface is provided for Lifeline POTS. Built with the carrier in mind, the Total Access 600 IADs are housed in a rugged metal case and provide the flexibility needed for quick turn-up in harsh environments. Wall and desktop mounting options are available for ease of installation. An optional ADTRAN battery backup system is available for added security. The integral IP router provides a powerful suite of performance and security features. Each Total Access 600 IAD offers multiple PVC configurations for simultaneous access to the corporate network and the ISP. Supporting NAT/PAT and packet filtering, Total Access 600 IADs secure the corporate network from unwanted intrusion. All configuration options, testing parameters, and passwords are accessed through an easy-to-use VT100 terminal interface or a TELNET session using the 10/100BaseT port. Using local or remote inband management, the service provider can turn features, functions, and access ports on and off. For network access, the Total Access 600 IADs have a single T1, SDSL, or SHDSL interface that is compatible with today's industry-leading DSLAMs.
