The Cisco PA-A2-4E1XC-OC3SM= is a high-performance network adapter designed to enhance versatility in network connectivity. This module offers a combination of both ATM (Asynchronous Transfer Mode) and high-speed Ethernet services. Featuring five ports, the primary connection capabilities include four E1 and one OC-3 port, allowing for integration into different networking systems or configurations.
The four E1 ports provide connectivity over the E1 standard (a European digital transmission format commonly used in telecommunications), offering a reliable data rate of up to 2.048 Mbps per port. This delivers stable, high-performance transmission for large-scale network operations or data centres. The OC-3 port is designed for fibre optic networks and is capable of supporting 155 Mbps data transfer speeds over a single-mode fibre link, ideal for long-distance communication.
The PA-A2-4E1XC-OC3SM= adapter is part of Cisco's extensive range of networking solutions and is primarily used to connect high-demand enterprise environments that require both ATM and Ethernet data transfers. It supports extended connectivity between different network infrastructures, enabling streamlined interoperability and data flow between sites. The interface operates on a Cisco architecture, designed to maintain high reliability and robust performance for enterprise deployments.
This network adapter is best suited for businesses looking for a combination of E1 circuit and fibre optic connectivity. Supporting multiple port types within a single module, it reduces the need for separate modules or cables, helping optimise rack space and maintain a cleaner infrastructure.
