Nortel Meridian Dual Port DTI/PRI Card (NT5D12AG)

The NT5D12 is a dual-port 1.5 Mb DTI/PRI card (the DDP firmware functions in DTI or PRI mode) integrating the functionality of two QPC472 DTI/QPC720 PRI cards and one QPC414 ENET into one card. The NT5D12 occupies a single Network shelf slot and provides two DTI/PRI network connections, an optional connection to an external D-Channel Handler, the QPC757 D-Channel Handler Interface (DCHI) or NT6D80 Multi-purpose Serial Data Link (MSDL), and an optional plug-on NTBK51AA Downloadable D-Channel daughterboard (DDCH.) The NT5D12 DDP card supports all features (except the echo canceller and protocol conversion) of the QPC720. In addition, it maintains the backward compatibility of QPC720. The NT5D12 DDP card hardware design uses a B57 ASIC E1/T1 framer. The carrier specifications comply with the ANSI TI.403 specification. The NT5D12 provides an interface to the 1.5 Mb external digital line either directly or through an office repeater, Line Terminating Unit (LTU), or Channel Service Unit (CSU).
