Nortel 25UMU00713DFK: PDMX 8-34 Mbit/s muldex card for Nortel telecommunications transmission and networking systems.

The Nortel 25UMU00713DFK is an 8 to 34 Mbit/s multiplexer-demultiplexer (muldex) card, aggregating a group of lower-rate PDH tributaries up to a 34 Mbit/s line. It belongs to Nortel’s PDMX family, a programmable digital multiplexer built as a complete transmission system for private-network operators carrying voice and data traffic over PDH (plesiochronous digital hierarchy) circuits, where a shelf’s common control unit interfaces to the 2 Mbit/s trunk and individual plug-in tributary cards give access to subscriber and other outlets. PDMX shelves of this generation are still found supporting legacy private circuits at utilities, transport operators and other private-network users who have not yet migrated off PDH transmission, and a genuine spare such as this is a routine requirement for maintaining shelf capacity or restoring a failed channel. 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) tests refurbished Nortel spares of this kind before they go back into service. Please contact our sales team for current stock and pricing.
