Avaya 847613742 TN746B 16-port analog line card for Definity/Communication Manager systems.

The Avaya 847613742 is a TN746B (also referenced as F746B) 16-port analog line card designed to provide analogue telephone line connections within Avaya telephony systems. This circuit pack enables the connection of standard analogue devices such as single-line telephones, fax machines, modems, and analogue door phones to the digital PBX infrastructure.

The TN746B analog line card is designed for use in Avaya Definity and Communication Manager platforms, installed within the system’s carrier or port network cabinet. It delivers loop-start analogue line functionality across 16 ports, making it suitable for environments requiring integration of legacy analogue endpoints alongside digital or IP telephony.

This is a legacy card associated with Avaya’s traditional PBX systems. Whilst these platforms remain operational in many enterprise environments, the TN746B is typically sought as a replacement or spare part to maintain existing installations rather than for new deployments.
