BLOCK DIAGRAM
Figure A–2 is a basic functional block diagram of the MC145572EVK ISDN U–Interface Evaluation
Kit. Note that the dashed line represents the physical and logical separation between the LT and the
NT1 sides of the evaluation board. While the board is capable of activating “standalone”, the user
may decide to use a single ASCII terminal to gain total control of the MC145572EVK capabilities.
Or the user may choose to split the board, allowing the LT and NT1 portions to be physically located
in separate areas.
