Description
The 3Com 3CB9NAL4R is a specialized interface daughter card designed to expand the capabilities of the 3Com CoreBuilder 9000 modular chassis. This card provides a single port that supports OC-3C/STM-1 Asynchronous Transfer Mode (ATM) connectivity, a high-speed networking protocol commonly used for Wide Area Networks (WANs) and Metropolitan Area Networks (MANs). The OC-3C/STM-1 standard operates at a data rate of 155.52 Mbps, offering a robust and reliable connection for demanding network applications. The ATM protocol is known for its ability to handle both voice and data traffic efficiently by segmenting data into fixed-size cells, ensuring quality of service for time-sensitive applications. This makes the 3CB9NAL4R ideal for service providers and large enterprises requiring high-bandwidth, low-latency connections. As a daughter card, the 3CB9NAL4R is designed to be installed within the CoreBuilder 9000 chassis, allowing for flexible and scalable network configurations. Its purpose is to enable the CoreBuilder platform to connect to ATM networks, facilitating high-speed data transport and integration into existing ATM infrastructure. This component is crucial for building high-performance backbone networks and providing advanced connectivity services.
