Nokia 472573A.104 FXDB foreign exchange subscriber line interface module.

The Nokia 472573A.104 is an FXDB (Foreign Exchange D-side B) interface module designed for Nokia telecommunications systems. This module provides analogue subscriber line interfaces, enabling the connection of traditional analogue telephone devices or fax machines to digital switching platforms.

FXDB modules are typically deployed within Nokia’s fixed-line access and switching infrastructure, allowing network operators to support legacy analogue services alongside digital and IP-based communications. These cards are essential for maintaining PSTN connectivity in hybrid network environments.

This is a legacy Nokia telecommunications component from earlier-generation switching and access platforms. While these systems remain operational in many deployed networks, they represent mature technology that may be approaching end-of-life in some installations.
