NORTEL 25UMU00722EHR: A muldex card converting between the 8 Mbit/s and 34 Mbit/s levels of the PDH hierarchy for the Nortel PDMX transmission platform.

The Nortel 25UMU00722EHR is a muldex card converting between the 8 Mbit/s and 34 Mbit/s levels of the PDH hierarchy, a plug-in card for Nortel’s PDMX (Programmable Digital Multiplexer) platform. PDMX is a private-network PDH transmission system built around a common control unit interfacing a 2 Mbit/s trunk, with a range of plug-in tributary, clock, protection-switching and power cards configuring each shelf for its role. Genuine Nortel spares like this one keep active PDMX shelves running, cover redundancy after a card fault, and support planned capacity upgrades on existing installations. Card revisions vary across the PDMX’s long service life, so confirm the shelf slot and revision this unit replaces before ordering.
