Model 7510 DSU Features
The DSU provides an interface between the customer premises equipment (CPE)
and a Digital Data Service (DDS) network.
The DSU’s features and capabilities include:
Easy Installation. Connects to your equipment using standard connectors
and cables.
1
Easy Configuration. A compact and well-thought set of configuration options
minimizes your customization effort.
DDS Operation. Operates at 56 and 64 kbps CC (clear channel).
Local Area Data Set (LADS) Operation. Operates at 56 and 64 kbps
full-duplex as a limited-distance modem.
Autorating. Automatically adjusts to the detected line rate.
Data Port Rates. Automatically adjusts to the DDS or LADS operating rates.
Asynchronous T erminal Interface (ATI). Provides a menu-driven
VT100-compatible interface for configuring and managing the DSU.
— Local Management. Provides local management using an asynchronous
terminal connection through the Terminal port.
— Remote Management. Provides remote management using an external
modem through the Terminal port.

Using the Asynchronous Terminal Interface
Connecting to the Terminal Port
The device used for the Asynchronous Terminal Interface (ATI) can be a
VT100-compatible async terminal, or a PC running emulation software. The
terminal or PC can be connected to the Terminal port directly, or through an
external modem.
Ensure that the device you connect communicates using these settings:
2
Data rate set to 9.6 kbps.
Character length set to 8.
Parity set to None.
Stop Bits set to 1.
Terminal port settings cannot be changed from the ATI.
