Nortel NTLX93CG (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTLX93CG is a CTU (Central Terminal Unit) PCM30 coaxial cabling kit, identified by its NTLX part-number prefix as belonging to the same family as the Nortel Passport SPM (Shelf Processor Module) hardware this catalogue has documented in prior listings, including the NTLX56AA fan assembly, NTLX55AA cooling unit and NTLX51BA high-speed backplane. PCM30 (E1, 2.048 Mbit/s, 30 usable channels) is the standard European primary-rate trunk format, and a CTU coaxial kit of this kind provides the 75-ohm coax connections needed to bring E1 trunks into a Passport shelf’s central terminal position. Passport equipment of this generation remains in service on established carrier and enterprise networks where E1 trunking is still standard, and genuine cabling kits such as this one are a routine requirement when expanding trunk capacity or replacing damaged coax runs. Specifiers should confirm exact shelf and slot compatibility against their specific Passport configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel Passport hardware to support ongoing network maintenance projects.
