Nortel NTNQ01AA Passport 7400 CP2 Control Processor module (NNTM0350).
The Nortel NTNQ01AA is a CP2 Control Processor module for the Passport 7400 multiservice switching platform, also referenced under the internal designation NNTM0350. It provides the switch’s central control-plane processing.
The CP2 control processor manages the Passport 7400 chassis, coordinating the function processor (interface) cards installed elsewhere in the shelf and running the switch’s control-plane software. Control processor modules such as this were a core, field-replaceable component of the Passport architecture, and could be deployed in redundant pairs for resilience.
Passport 7400 systems were used by carriers and large enterprises for combined ATM, Frame Relay and IP multiservice switching. Tech-Star (UK-based, shipped worldwide) checks every module before it ships. Get in touch to confirm compatibility with your Passport 7400 system.
