The Nortel NTHW31AG is a 16-port OC-3/STM-1 ATM single-mode Function Processor for the Nortel Passport Multiservice Switch (MSS 15000/20000) platform, part of the documented NTHW31-prefixed Function Processor family alongside confirmed sibling cards such as NTHW31AC and NTHW31AB. It aggregates up to 16 OC-3c/STM-1 ATM ports over single-mode fibre into the Passport switch fabric, giving considerably higher port density per card than the 4-port NTHW-series Function Processors used on smaller Passport shelves. Passport MSS 15000/20000 systems remain in service across a number of established carrier ATM/IP networks, and genuine high-density Function Processor cards such as this one are a routine requirement for maintaining full port capacity or restoring redundancy after a card failure. Specifiers should confirm the exact optics reach and shelf compatibility against their specific Passport configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel Passport Function Processor cards to support ongoing network maintenance. Please contact our sales team to confirm exact compatibility and for current stock and pricing.
