Avaya 847060753 TN746B 16-port analogue line card for Definity/Communication Manager systems.

The Avaya 847060753, also known as the TN746B (or F746B), is a 16-port analogue line circuit pack designed for Avaya PBX systems. This card provides connections for analogue station devices such as single-line telephones, fax machines, modems, and other analogue endpoints within an enterprise telephony environment.

The TN746B is used within Avaya Definity and Communication Manager platforms, fitting into the system’s port carrier to expand analogue line capacity. It is commonly deployed in environments where legacy analogue devices must be integrated alongside digital and IP telephony infrastructure.

This is a legacy circuit pack from the Avaya Definity/Communication Manager product line. While these systems remain operational in many enterprises, the TN746B is typically sourced as refurbished stock for maintenance, expansion, or spares purposes.
