The Total Access 1500 (TA 1500) is a Carrier Class, multi-service access platform for deploying narrowband and xDSL services from TDM or ATM backbone infrastructures. A small, extremely versatile platform, TA 1500 integrates the functionality of many carrier products into a single high-density chassis. TA 1500's small footprint (2U-high mounting) makes it the perfect choice for integrated communications providers such as ILECs, CLECs, and ISPs, who need to deploy services from crowded Remote Terminals (RTs), Central Offices (COs), or Co-Location (COLO) facilities. TA 1500 provides a variety of services including POTS, special services (ISDN, DDS, FXO, FXS, E&M, DPO, DPT, and PLAR), and xDSL. TA 1500 complements ADTRAN's Total Access 3000 broadband multi-service access platform, which can terminate and distribute higher bandwidth services such as SONET, DS3, HDSL, HDSL2, T1, and Optical DS2. This specific model is designed for government use.
