Nortel NTBX71AA (telecommunications transmission and networking portfolio) Power Supply Image 1

The Nortel NTBX71AA is a power supply unit for the ISDN line-card shelf of the Nortel DMS-100 central-office switching platform.

The Nortel NTBX71AA is a power supply unit for the ISDN line-card shelf of the Nortel DMS-100 central-office digital switching platform, part of the documented material-code family Nortel used across DMS-100 and DMS-100E power and interface hardware. ISDN shelves on a DMS-100 exchange carry Basic Rate and Primary Rate line cards that need a dedicated, closely-regulated DC feed separate from the switch’s main -48V plant, and this unit is the converter card that provides it. DMS-100 exchanges remain in service in a number of established telecoms networks, and genuine power spares such as this one are a routine requirement for maintaining shelf redundancy after a unit failure. Tech-Star (UK-based, shipped worldwide) stocks Nortel DMS-100 cards to support ongoing exchange maintenance. Please contact our sales team to confirm exact compatibility and for current stock and pricing.
