472569A Nokia Nokia Fixed Network Access Telecom System Card

The Nokia 472569A is an FXFB (Foreign Exchange Station B-side) interface module designed for Nokia telecommunications systems. This card provides analogue subscriber line interfaces, enabling the connection of traditional analogue devices such as telephones, fax machines, and modems to digital switching infrastructure.

FXFB modules are typically deployed within Nokia’s fixed-line network equipment, serving as the interface between the digital core network and analogue end-user equipment. These cards are essential for providing POTS (Plain Old Telephone Service) connectivity in environments where legacy analogue devices must be supported alongside modern digital infrastructure.

This is a legacy Nokia module associated with older fixed-network switching platforms. While no longer in active production, these cards remain in demand for maintenance and spares purposes in networks where Nokia analogue access equipment continues to operate.
