Avaya TN2793B: 24-port analogue line circuit pack for Avaya Definity/G3 PBX.

The Avaya TN2793B is a 24-port analogue line circuit pack for the Avaya Definity/G3 PBX platform (the same TN-card architecture carried forward into later Avaya Communication Manager systems), giving the system 24 ports of loop-start analogue extension connectivity for ordinary telephones, fax machines and similar analogue devices from a single card.

Definity was AT&T’s and then Lucent’s enterprise PBX, carried forward by Avaya as Communication Manager, and it is built from a cabinet of TN-prefixed circuit packs. Each pack does one job: line cards for extensions, trunk cards for outside circuits, tone and announcement packs for the system’s own audio, and control packs for the processor complex. The platform ran for decades with the same physical card format, which is why individual packs are still traded and still fit.
