About This Part
The Nokia 21 x E1 IO 75 Ohm card (S42024-L5480-A1) is a critical interface component designed for high-density E1 connectivity within telecommunications and data centre environments. This card facilitates the termination and transmission of 21 individual E1 circuits, which are fundamental for carrying voice, data, and signaling traffic in traditional digital networks. It is typically deployed within a larger Nokia chassis, such as a multi-service access node or a transport platform, enabling operators to extend legacy services, interconnect different network segments, or provide dedicated leased lines to enterprise customers. Its robust design ensures reliable performance in demanding operational settings. Key technical specifications derived from the product name highlight its capacity and compatibility. With 21 E1 input/output ports, this card offers substantial connectivity for managing multiple digital streams. The 75 Ohm impedance specification is standard for E1 coaxial cable connections, ensuring seamless integration with existing network infrastructure and equipment that adheres to ITU-T G.703 recommendations. As an I/O card, it handles the physical layer termination, converting electrical signals for processing by the host system, thereby maintaining signal integrity and network performance.
