Nortel NTDY29BA (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NTDY29BA is an SCC (System Control Card) line termination card for the Nortel CVX-1800 platform, decoded directly from its own part label. The CVX-1800 is a Nortel access concentrator with 18 total chassis slots, two of which are dedicated to system control cards while the remaining 16 support digital access or modem access cards, and this SCC line-termination card handles the physical trunk termination associated with the shelf’s control function. CVX-1800 platforms were widely deployed by carriers and ISPs for dial-up and digital access aggregation, and equipment of this generation remains in service on a number of established legacy access networks. Genuine SCC spares such as this one are a routine requirement for maintaining control-card redundancy, since a CVX-1800 shelf typically runs a protected pair of system control cards. Specifiers should confirm exact revision and firmware compatibility against their specific CVX-1800 configuration before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel CVX-1800 hardware to support ongoing network maintenance projects.
