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/NTBK51CA 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.
The NT5D97 DDP2 card hardware design uses a B57 ASIC framer. The carrier specifications
comply with the ANSI TI.403 specification. The NT5D97 provides an interface to the 2.048
Mbps external digital line either directly or through an office repeater, Network Channel
Terminating Equipment (NCTE), or Line Terminating Unit (LTU).
