The Nortel NTNQ25AA is a one-port E3 Function Processor for the Nortel Passport/Multiservice Switch (MSS) platform, part of the documented NTNQ-prefixed family of Passport function processor cards. It provides a single E3 (34.368Mbps) interface for carrying higher-rate data or trunk traffic into and out of a Passport/MSS shelf, sitting alongside the family’s E1-rate and ATM function processor cards at the next capacity tier up. Passport/MSS shelves of this generation remain in service across a number of established carrier and enterprise data networks, and genuine function processor cards such as this are a routine requirement for maintaining E3 trunk capacity or restoring a failed card. Specifiers should confirm exact compatibility against their specific Passport/MSS shelf configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel Passport cards to support ongoing network maintenance. Please contact our sales team for current stock and pricing.
