INTRODUCTION
1.1
ORGANIZATION OF DATA SHEET
This document is composed of three major sections. Section 1 introduces the MC145572EVK U-Interface
Transceiver Evaluation Kit with a brief description of the evaluation board and a list of key features. Also
included at the end of Section 1 is Getting Started, a short tutorial to help begin working with the
MC145572EVK. Section 2 is a brief description of the hardware design. Section 3 contains the command
set descriptions and examples.
IMPORTANT NOTE
This Users Manual MC145572EVK U-Interface Transceiver Evaluation Kit Revision 2
corresponds with MC145572EVK Printed Circuit Board Revision F with rmware version
2.01. If a discrepancy exists between this document and the MC145572 data sheet, the
MC145572 data sheet should take precedence.

INTRODUCTION
The MC145572EVK U-Interface Transceiver Evaluation Kit provides Motorola ISDN customers a
convenient and efcient vehicle for evaluation of the MC145572 ISDN U-Interface Transceiver. The
approach taken to demonstrate the MC145572 U-Interface Transceiver is to provide the user with a fully
functional NT1 (Network Termination Type 1) connected to an LT (Line Termination). An NT1 provides
transparent 2B+D data transfer between the U- and S/T-Interfaces. In addition, it provides for network
initiated maintenance procedures. The MC145572EVK does not terminate any ISDN call control
messages. It also does not terminate any maintenance messages received over the S/T-Interface.
The MC145572EVK U-Interface Transceiver Evaluation Kit can be used as an NT1 card or as an LT card.
The left half of the card is the NT1, while the right half of the card is the LT. Alternatively, it can be thought
of as having both ends of the two-wire U-Interface, extending from the customer premise (NT1) to the
switch line card (LT) on a single, stand-alone evaluation board. Figure 1-1 shows a typical ISDN application
using the MC145572 and the MC145574.
The kit provides the ability to interactively manipulate status registers in the MC145572 U-Interface
Transceiver as well as in the MC145574 S/T-Interface Transceiver with the aid of an external terminal. A
unique combination of hardware and software features allows for stand-alone or terminal activation of the
U-Interface and as such provide an excellent platform for NT1 and LT hardware/software development.
The NT1 function can be disabled by putting DIP switch S4-10 in the NT1 DIS position.
