Nortel 25UPJ00722DHQ: PDMX tone-signalling processor card for Nortel telecommunications transmission and networking systems.

The Nortel 25UPJ00722DHQ is a tone-signalling processor card for the PDMX platform, generating and detecting the audio tones used to signal calls across the multiplexed circuits. 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. Card revisions on this platform can vary between shelf software loads, so confirm exact compatibility against your installed system before ordering. 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.
