Nortel NTEP39BA (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTEP39BA is a shelf assembly component for the Passport wide-area switching platform. Passport shelf hardware of this kind typically comprises the mechanical rack or subrack structure, backplane sections, or mounting assemblies that the platform’s active function processors, control processors and power modules are fitted into, rather than an active electronic card in its own right. Passport 6400/7400 and Passport 15000 nodes both use shelf-level assemblies of this general kind, and a number of them remain in service across long-running carrier and enterprise WAN cores, where mechanical spares are needed alongside the active cards to keep an ageing shelf serviceable. Tech-Star (UK-based, shipped worldwide) stocks Passport shelf hardware for ongoing chassis maintenance.
