Adtran Dedicated DDS, T1, and E1 Disaster Recovery

• ATLAS
  The ATLAS Series of IADs offers the highest capacity and most advanced set of networking services. From a single platform, ATLAS can support multiple technologies including T1, T3, ISDN, IP routing, and Frame Relay. IT managers and network engineers of small, medium and large enterprise networks may choose ATLAS for its ISDN conversion and oversubscription features, T1 Inverse Multiplexing, ISDN PRI/BRI switching, multiple T1/PRI DACSing and grooming, Frame Relay concentration/switching, compressed voice, T3 applications, and videoconferencing.

  This multi-T1/PRI enterprise platform converges voice, data, video, and Internet traffic through dynamic bandwidth allocation, T1 Inverse Multiplexing, circuit switching, and packet routing. The ATLAS 550 is designed for the small-to-medium networks with one to 18 T1/PRI ports, while the ATLAS 830 is designed for medium-to-large networks that require up to 34 T1/PRI ports or a T3. The ATLAS 890 supports up to 64 T1/PRI ports or a T3 and can be used in networks that require full system redundancy.

  For global applications, the ATLAS Series also offers a range of interfaces including E1, ISDN PRA and BRI S/T, along with support for Net-3 and Net-5 Euro-ISDN protocols.

• DSU
  The DDS Series of products offers a wide range of high performance, cost-effective DSU/CSUs. The ADTRAN DSU family of products includes standalone and rackmount products that incorporate many different features like SNMP management, automatic dial backup, auto-rate adaption, user-slectable options, external DTE master circuit clock, as well as weekend and time of day lockout options.
• ESU
  ADTRAN offers a series of E1 network termination devices to support multi-national applications involving high-speed data across E1 circuits. The ESU Series offers the same data modularity and flexibility found in ADTRAN's industry-leading T1 DSU/CSU and multiplexer products. The ESU 120e includes embedded SNMP management and allows users to grow their capabilities by adding interface modules to the built-in expansion slot.
• TSU Multiplexers
  ADTRAN's TSU Multiplexer Series redefined the T1 multiplexer marketplace in 1994. Today, this equipment is some of the most reliable and respected for aggregating multiple voice only or voice and data services onto T1 or FT1 bandwidths.

  The intelligent TSU and TDU devices offer either one (1XX series) or six (6XX series) expansion slots, with up to four interfaces per slot. More than thirty plug-in and plug-on modules are available to support analog voice, Nx56/64 data, subrate data, disaster recovery, and other applications. The "e" series devices additionally include SNMP management via a SLIP or 10BaseT port, an enhanced terminal screen, and N-Form support.
