Nortel NT1X62CB (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NT1X62CB is a CP I/O Message Controller card in the NT1X-prefixed Central Processor (CP) family used on the DMS-100 switching platform. It manages input/output message traffic between the DMS-100 Central Processor and the exchange’s peripheral and maintenance subsystems, a function that sits at the core of the switch’s call-processing and system-management architecture. DMS-100 is a large-scale carrier-grade digital switching exchange historically deployed by network operators for local and trunk switching, and its Central Processor complex depends on cards of this kind to keep peripheral messaging synchronised across the office. DMS-100 exchanges remain in service in a number of established telecoms networks, and genuine CP spares are a routine requirement for maintaining full system capacity or restoring redundancy after a card failure. Tech-Star (UK-based, shipped worldwide) stocks Nortel DMS-100 cards to support ongoing exchange maintenance.
