Nortel NTNQ21AA: Passport/MSS four-port E1 Channelized Function Processor (Premium) for Nortel telecommunications systems.

The Nortel NTNQ21AA is a four-port E1 Channelized Function Processor (Premium grade) for the Nortel Passport/Multiservice Switch (MSS) platform, part of the documented NTNQ-prefixed family of Passport function processor cards. It provides four channelized E1 (2.048Mbps) interfaces, each of which can be subdivided into individual timeslots for carrying multiple lower-rate circuits over a single E1 link, and the Premium grade denotes a higher-capacity or higher-feature hardware variant within the NTNQ family. 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 E1 trunk capacity. 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.
