The DS2149DK/DS21349DK is a fully integrated design kit for the DS2149 and the DS21349 T1/J1 line interface units (LIUs). It contains the necessary circuitry to evaluate the device in all operation modes, including running the device in hardware and software mode.
The document details the DS2149DK/DS21349DK Design Kit, a fully integrated board containing circuitry to evaluate the DS2149 and DS21349 devices in both hardware and software modes. The kit includes necessary components such as PLCC sockets, Bantam and RJ48 connectors, transformers, and an on-board 8051 microprocessor for software mode access.
The guide provides instructions on board layout, component lists, line-side connections, and system connector usage. It also explains how to install and run the DemoView software for register read/write operations and offers basic configuration steps for setting up T1 hardware and software modes with external remote loopback.

The kit is a fully integrated design kit for the DS2149 and the DS21349 T1/J1 line interface units.
The board contains an on-board 8051 microprocessor with factory-installed firmware to translate memory access requests into register access.
DemoView, a general-purpose program created by Dallas Semiconductor, allows easy read-write access for this device.
