(ARCHIVED) ISDN U-Interface Transceiver Evaluation Kit

ARCHIVED

The MC145572EVK U-Interface Transceiver Evaluation Kit provides a convenient and efficient vehicle for evaluation of the MC145572 ISDN U-Interface Transceiver.

The user is provided 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 ISDN call control or maintenance messages

The Kit can be functionally separated into two "halves." The left half of the card is the NT1, while the right half of the card is the LT. Alternately 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.

The kit provides the ability to interactively manipulate status registers in the MC145572 U-Interface Transceiver as well as in the MC145474 S/T-Interface Transceiver with the aid of an external terminal. An appropriate combination of hardware and software features allows for standalone or terminal activation of the U-Interface, and, as such, provides an excellent platform for NT1 and LT hardware/software development.

The MC145572EVK can be interfaced to the MC68302 Family Application Development System (M68302FADS), to support the hardware and software development of S/T- and U-Interface terminal equipment.
