Adtran 1202011L1 DSU III AR Data Service Unit
Brand New Sealed Item
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.
All-rate DSU/CSU module with automatic rate adaption.
Provides V.35 and EIA-232 serial interfaces.
Synchronous loop and DTE rates from 2.4 kbps to 64 kbps.
Asynchronous DTE rates from 2.4 kbps to 57.6 kbps.
Asynchronous secondary port operates at 75 bps to 2400 bps, depending on primary channel rate.
Manual, DTR Dial, AT Commands, V.25 bis, or stored number dialing.
Derives timing from an internal oscillator, the network, or an external DTE device.
