Introduction

This section contains information required to install the NT5D97 Dual-port

DTI2/PRI2 (DDP2) card.

The NT5D97 is a dual-port 2.0 Mb DTI2/PRI2 card (the DDP2 firmware functions in DTI2 or PRI2 mode, depending on DIP switch settings) that integrates the functionality of two NT8D72BA PRI2 cards, and one QPC414 ENET card into a single CE card. The NT5D97 occupies a single slot in the Network shelf and provides two DTI2/PRI2 network connections: an interface to an external D-Channel Handler (the NT6D11AF) or the NT6D80 Multi-purpose Serial Data Link card, and an optional plug-on NTBK51AA Downloadable D-Channel daughterboard (DDCH) with two DCH interface ports.

The NT5D97 DDP2 card can be mixed in the same machine with PRI2

NT8D72BA cards.
