Product Description
The 3Com 3CB9NAK1SC is a specialized interface card designed for the 3Com CoreBuilder 9000 series of modular switches. This card provides a single port operating at OC-12c/STM-4 speeds, which corresponds to a data rate of 622 Mbps, specifically for Asynchronous Transfer Mode (ATM) networking. ATM was a key technology for high-speed backbone networks and broadband services, offering efficient cell-based switching and Quality of Service (QoS) guarantees. This interface card enables the CoreBuilder 9000 switch to connect to ATM networks, which were prevalent in telecommunications backbones and early broadband deployments. It allows organizations to integrate their data networks with ATM infrastructure, facilitating high-speed data, voice, and video transmission. The card's modular design ensures it can be easily installed or replaced within the CoreBuilder chassis, providing flexibility for network upgrades and maintenance. The 3CB9NAK1SC card supports the necessary ATM protocols and signaling required for establishing and managing ATM connections. Its high-speed capability at the time of its introduction made it suitable for demanding applications requiring reliable, low-latency data transport. This card represents a component for building robust and high-performance network backbones using ATM technology within the 3Com ecosystem.
