Nortel NT1X81AA: DMS-100 Conference Trunk Module for central-office conference-call bridging.

The Nortel NT1X81AA is a DMS-100 Conference Trunk Module (CONF TRK MOD), a peripheral circuit pack that provides multi-party conference-bridging resources within a Nortel DMS-100 digital central-office switch. It sits in the switch’s trunk peripheral shelf, mixing audio from multiple call legs so operator or subscriber conference-calling features can be offered across the office. DMS-100 exchanges of this generation remain in service across many established telecoms networks, and genuine spares like this restore full conferencing capacity after a card failure or support an office’s rated conference-trunk count. Specifiers should confirm exact frame and generic-program-load compatibility before ordering. Tech-Star is UK-based and ships worldwide. Contact our sales team for current availability and pricing.
