C109976 Nokia Nokia Transmission Systems Telecom System Card

The Nokia C109976 is a B.ISFD (Broadband ISDN Fiber Distribution) interface module designed for Nokia telecommunications infrastructure. This component provides fibre-based connectivity for broadband ISDN services within carrier-grade network deployments.

This module is typically deployed within Nokia’s transmission and access network platforms, serving as an interface card that bridges fibre optic distribution systems with ISDN services. It enables operators to deliver broadband connectivity over fibre infrastructure to enterprise and residential customers.

The C109976 is a legacy Nokia component from earlier generations of telecommunications infrastructure. While no longer in active production, these modules remain in demand for maintaining and extending existing Nokia network deployments where complete system replacement is not practical or cost-effective.
