Nortel 25UMN00750GXD: TN-1X subrack controller, the card that supervises the shelf and carries its management interface. Confirm the release before ordering.

The Nortel 25UMN00750GXD is a subrack controller for the TN-1X, Nortel’s STM-1 add and drop multiplexer. The subrack controller supervises the shelf, holds the node configuration and provides the management interface through which the multiplexer is driven. Release and revision suffixes vary within this part number, so tell us the system it is going into and we will confirm the exact unit we hold.

TN-1X nodes are still carrying traffic in SDH access rings, and the platform is maintained rather than replaced. Each shelf combines a controller, payload management, tributary units and traffic access modules, so operators running TN-1X sites normally keep matched spares for every slot type they depend on.

Tell us what you are replacing and we will inspect the stock item, read the label and confirm the release before we quote. Tech-Star (UK-based, shipped worldwide) supplies tested Nortel hardware on a quote-only basis. Contact our sales team for current availability, condition and pricing.
