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.
