NORTEL 25UPB50713AAA: A muldex (multiplexer/demultiplexer) card converting between the 2 Mbit/s and 8 Mbit/s levels of the PDH hierarchy for the Nortel PDMX transmission platform.

The Nortel 25UPB50713AAA is a muldex (multiplexer/demultiplexer) card converting between the 2 Mbit/s and 8 Mbit/s levels of the PDH hierarchy, a plug-in card for Nortel’s PDMX (Programmable Digital Multiplexer) platform. Nortel’s PDMX system carries private-network PDH traffic through a shelf built around a control unit and a set of interchangeable tributary, power and protection-switching cards. Where a PDMX shelf is still carrying live traffic, a genuine spare such as this restores full capacity or redundancy without disturbing the rest of the installation. Card revisions vary across the PDMX’s long service life, so confirm the shelf slot and revision this unit replaces before ordering.
