Avaya 848179560 TN746B 16-port analog line card for Definity and Communication Manager systems.

The Avaya 848179560, also known as the TN746B (or F746B), is a 16-port analog line circuit pack designed to provide connections for analogue telephone sets and devices. This card enables traditional analogue endpoints to integrate with Avaya’s digital PBX infrastructure, supporting basic telephony functions including dial tone, ringing, and voice transmission.

The TN746B is intended for deployment within Avaya Definity and Communication Manager systems, where it occupies a slot in the system’s carrier or port network. Each of the 16 ports can support a standard analogue telephone, fax machine, modem, or other analogue device, making it suitable for environments requiring legacy device connectivity alongside digital and IP telephony.

This circuit pack is a legacy component from Avaya’s established Definity and Communication Manager product lines. Whilst these systems remain in active service across many enterprise installations, the TN746B is no longer in current production. It remains a practical solution for maintaining or expanding analogue capacity in existing deployments.
