Nortel NT5K71AA (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NT5K71AA is recorded on our supplier data as an XCOT/PPM card. That reads as a central office trunk card with periodic pulse metering, the metering pulse arrangement used on some European and international circuits, but our record does not confirm the port count or the exact Meridian variant. That designation is what our supplier record gives, and we have not expanded it beyond what we can support, so treat the wider detail as unconfirmed until we have checked the unit.

Meridian 1 is Nortel’s large enterprise PBX family, later continued as Communication Server 1000. A system is built from common equipment, network and peripheral shelves, with intelligent peripheral equipment cards providing the line, trunk and service circuits. A great many are still in daily use, and they are maintained by replacing individual cards.

Send us the platform and slot you are filling, or a picture of the front panel legend, and we will confirm the match physically before anything ships. Tech-Star (UK-based, shipped worldwide) sources and supplies Nortel hardware to order. Get in touch with our sales team for availability, tested condition and a price.
