Nortel NTNN55AA: Passport OC3S Functional Processor (FP) Module.

The Nortel NTNN55AA is an OC3S Functional Processor (FP) Module for the Nortel Passport multiservice switching platform, the same OC3S FP card family documented on sibling Passport modules (NTNQ55AA, NTFP38DA) across the Passport 6400/6480/6840/7400 shelf range. It provides OC-3/STM-1 ATM interface capacity, terminating the optical line and handing ATM cells to the shelf’s switch fabric. Passport shelves of this generation remain in service across a number of legacy carrier ATM networks, and OC3S FP modules of this type are a routine spares requirement for maintaining line capacity or restoring redundancy after a card failure. Confirm the exact Passport chassis variant before ordering, since OC3S FP cards are not interchangeable across every Passport model. Tech-Star (UK-based, shipped worldwide) supplies Nortel Passport spares to support ongoing network maintenance.
