Avaya TN2793B Definity / Communication Manager PBX Expansion Card Image 1

Avaya TN2793B 24-port analogue line card for Definity and Communication Manager systems.

The Avaya TN2793B is a 24-port analogue line card designed to provide connectivity for analogue devices within Avaya’s enterprise communication platforms. This circuit pack enables the connection of standard analogue telephones, fax machines, modems, and other analogue endpoints to the PBX system.

The TN2793B is engineered for deployment in Avaya Definity and Avaya Communication Manager systems, serving as a key component for organisations that require analogue line capacity alongside their digital and IP telephony infrastructure. Each port supports a single analogue device, making it suitable for environments with significant analogue endpoint requirements.

This is a legacy product associated with Avaya’s traditional PBX platforms. While these systems remain in active service across many enterprise installations, the TN2793B represents mature technology that continues to support existing infrastructure and migration strategies.
