Avaya 700393408 Facility Test Card TN771DP for Definity/Communication Manager systems.

The Avaya 700393408 is a Facility Test Card, also referenced as TN771DP, designed for diagnostic and maintenance testing within Avaya Definity and Communication Manager PBX systems. This circuit pack enables technicians to perform automated testing and fault diagnosis on facility interfaces, trunk lines, and station ports within the telecommunications system.

The TN771DP is installed in the system’s universal equipment cabinet and works in conjunction with the system’s maintenance software to identify faults, verify circuit integrity, and support ongoing system health monitoring. It is an essential component for maintaining service quality and reducing downtime in enterprise telephony environments.

This is a legacy product associated with Avaya’s traditional circuit-switched PBX platforms, which have been largely superseded by IP-based solutions. However, many enterprises continue to operate Definity and Communication Manager systems, creating ongoing demand for replacement and spare components.
