Nortel NTNQ03AA (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTNQ03AA is a Control Processor with BITS Interface for the Nortel Passport/Multiservice Switch (MSS) platform, part of the documented NTNQ-prefixed family of Passport function processor and control-processor cards. The control processor manages shelf-level system functions and card supervision, and this variant adds a Building Integrated Timing Supply (BITS) interface so the shelf can synchronise to an external network timing reference rather than relying solely on its own internal clock. Passport and MSS shelves of this generation remain in service across a number of established carrier and enterprise data networks, and genuine control processor cards are a routine requirement for restoring shelf management or timing redundancy after a card failure. Specifiers should confirm exact compatibility against their specific Passport/MSS shelf configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel Passport control-processor cards to support ongoing network maintenance. Please contact our sales team for current stock and pricing.
