Tech Specs

The ADTRAN DSU III AR is a technologically advanced, high performance data service unit/channel service unit (DSU/CSU). This unit provides a reliable interface between the digital data service (DDS) or 4-wire Switched 56 (SW56) network and the customer's data terminal equipment (DTE). The unit is an all-rate DSU/CSU supporting synchronous and asynchronous data rates on the primary channel and asynchronous data rates on the secondary channel. The synchronous primary channel rates supported are 2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64 Kbps. Asynchronous data rates supported are 2.4, 4.8, 9.6, 19.2, 38.4 and 57.6 Kbps. Secondary channel data rates of 75, 150, 300, 600, 1200, and 2400 bps are offered depending upon the primary channel rate.
