Nortel 25UMU00736EQK: PDMX 2-34 Mbit/s jump-multiplexer card for Nortel telecommunications transmission and networking systems.

The Nortel 25UMU00736EQK is a 2 to 34 Mbit/s jump-multiplexer card, stepping a group of 2 Mbit/s tributaries directly up to a 34 Mbit/s line without the intermediate 8 Mbit/s stage. It is part of Nortel’s PDMX platform, a programmable digital multiplexer sold as a complete transmission system for private digital telecommunications networks, built around a bus-connected shelf where a control unit handles the 2 Mbit/s trunk interface and tributary cards provide the individual subscriber and data connections. Installations built on this platform remain in service wherever a private-network operator has not yet replaced its PDH transmission layer, and stock like this is typically bought to restore a failed card, keep an existing shelf at full capacity, or support ongoing maintenance of the installed base. Confirm shelf and revision compatibility against your own PDMX installation before ordering, as with any legacy transmission spare. Tech-Star (UK-based, shipped worldwide) sources and tests refurbished Nortel transmission spares to support installations still running this platform. Please contact our sales team for current stock and pricing.
