The Nortel NTLX57AG is a power supply and alarm module for the Nortel DMS-Spectrum peripheral module family, identified by its NTLX part-number prefix as belonging to the same family as Nortel’s documented DMS-Spectrum Shelf Interface Modules. DMS-Spectrum is a peripheral module used with the Nortel DMS-100 and DMS-250 family of carrier-grade digital switches, and its shelves rely on dedicated power and alarm cards to supply the shelf and report fault conditions back to the switch. DMS-Spectrum-equipped exchanges remain in service in a number of established telecoms networks, and genuine spares such as this one are a routine requirement for maintaining full shelf capacity or restoring alarm reporting after a card failure. Tech-Star (UK-based, shipped worldwide) stocks Nortel DMS-Spectrum hardware to support ongoing exchange maintenance. Please contact our sales team to confirm exact compatibility and for current stock and pricing.
