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.
The NT5D97 DDP2 card hardware design uses a B57 ASIC E1/T1 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).
