Nortel 25UMU00722DBR: PDMX multiplexer control card for Nortel telecommunications transmission and networking systems.

The Nortel 25UMU00722DBR is a multiplexer control card for the PDMX platform, interfacing the shelf to its 2 Mbit/s trunk and coordinating the tributary cards plugged into it. It is one of the plug-in tributary cards that make up Nortel’s PDMX system, a programmable digital multiplexer built for private digital telecommunications networks, where the shelf’s control unit interfaces to the 2 Mbit/s trunk and each tributary card handles a specific circuit type. This class of PDH transmission equipment is still active in a number of established private networks, and a card like this is typically sourced to replace a failed unit, restore shelf capacity, or support an existing installation through its remaining service life. As with any legacy transmission spare, confirm the exact card revision and shelf compatibility against your installed system before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel transmission spares, including cards of this type, to support ongoing maintenance. Please contact our sales team for current stock and pricing.
