INTRODUCTION
The MC145572EVK U-Interface Transceiver Evaluation Kit provides Motorola ISDN customers a convenient and efÞcient 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.
