Avaya 847306438 TN464F DS1 interface card for Definity/Communication Manager systems.

The Avaya 847306438, also known as the TN464F, is a DS1 interface card designed to provide T1/E1 digital trunk connectivity for Avaya PBX systems. This circuit pack enables the connection of digital trunk lines to the telephone switching system, facilitating voice and data transmission over standard DS1 facilities.

The TN464F DS1 card is engineered for use within Avaya Definity and Communication Manager platforms, serving as a critical component for connecting the PBX to the public switched telephone network (PSTN) or private tie lines. It supports standard DS1 signalling protocols required for enterprise telephony deployments.

This is a legacy product associated with Avaya’s traditional circuit-switched PBX architecture. While these systems remain operational in many enterprise environments, the TN464F represents mature technology that continues to be sought after for maintenance, spares, and system expansion purposes.
