Nortel NTPN33AG MSC 15000 Telecom System Card / Module

The Nortel NTPN33AG is an enhanced power alarm module manufactured by Astec for Nortel’s telecommunications switching platforms. It is listed by multiple legacy telecom parts dealers as an MSC (Mobile Switching Centre) card for the Nortel MSC 15000 platform, forming part of the alarm and power monitoring subsystem within the switch’s power distribution architecture and reporting fault and status conditions back to the system’s alarm management. As with other cards in the Nortel MSC 15000 range, it is designed as a field-replaceable module within the equipment frame to minimise downtime during maintenance or fault rectification. The NTPN33AG is a legacy component now mainly sourced through refurbished and surplus telecom equipment channels, used by operators still supporting Nortel MSC 15000 infrastructure or maintaining spares inventories for older mobile switching deployments. Tech-Star (UK-based, shipped worldwide) supplies this alarm module for engineers maintaining or repairing Nortel MSC 15000 switching equipment. Get in touch to check stock and pricing.
