Adtran DSU/CSU's

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.

T1 CSUs
A full line of T1 products from ADTRAN provides termination options ranging from economical to full-featured. ADTRAN's T1 CSU and single-port DSU/CSUs, many of which are offered in both standalone and rackmount configuratons, offer a T1 termination solution without the cost of additional features. ADTRAN's full-featured single port DSU/CSU, the TSU ESP, provides optional SNMP management and dial backup for an advanced network access solution.

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.

TSU Single-port DSU/CSUs
ADTRAN's full line of cost-effective single-port TSUs provide an interface between T1 or Fractional T1 service and the end user's Data Terminal Equipment (DTE) for applications such as LAN to LAN connectivity, Frame Relay circuit termination and dedicated videoconferencing.

The TSU ESP adds integral SNMP management and dial backup support which allows for automatic switched backup in the event of a dedicated T1 line failure. The backup features do not apply when the device is used to transparently pass frame relay traffic to an external router.
