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 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.
