Avaya TN750C Definity / Communication Manager PBX Expansion Card Image 1

Avaya TN750C Announcement circuit pack for Definity and Communication Manager systems.

The Avaya TN750C is an Announcement circuit pack designed to provide recorded announcement playback capabilities within Avaya PBX systems. This card stores and plays pre-recorded voice announcements to callers, supporting applications such as queue greetings, on-hold messages, and informational prompts.

The TN750C is deployed in Avaya Definity G3 and Communication Manager platforms, typically installed in the system’s port carrier or gateway chassis. It enables organisations to deliver professional recorded messages to callers without requiring external announcement hardware.

This is a legacy circuit pack associated with Avaya’s traditional TDM-based telephony infrastructure. While these systems remain in production use across many enterprises, the TN750C is no longer in active manufacture, making refurbished units a practical option for maintenance and expansion.
