Nortel NT8D42AC Meridian 1 PBX PBX Card / Module

The Nortel NT8D42AC is a card for the Nortel Meridian 1 enterprise PBX platform, part of the well-documented NT8D-prefixed material-code family used across Meridian 1 digital line cards, universal trunk cards and controller cards. Meridian 1 is a large-scale digital PBX platform widely deployed in enterprise environments, and cards such as this one provide line, trunk or control connectivity within the system’s shelf-based architecture, giving connected extensions and trunks full access to the PBX’s call-handling and feature functionality. As a genuine Nortel part, it is built to slot directly into a compatible Meridian 1 shelf without any compatibility concerns. Meridian 1 systems remain in service across many established enterprise telephony deployments, and genuine cards such as this one are a routine requirement for maintaining full system capacity, restoring redundancy after a card failure, or expanding an existing installation. Tech-Star (UK-based, shipped worldwide) stocks tested Nortel Meridian 1 cards to support ongoing PBX maintenance.
