Information
The Cisco 4OC12X/ATM-IR-SC is a line card module designed for use in Cisco 12000 Series routers. It provides four optical carrier 12 (OC-12) interfaces, which are used for high-speed data transmission over fiber optic networks. The "ATM-IR" in the name indicates that the module supports Asynchronous Transfer Mode (ATM) technology, specifically the inverse multiplexing over ATM (IMA) feature. The "SC" refers to the type of optical connector used on the module, which is the Subscriber Connector (SC) type. Overall, the Cisco 4OC12X/ATM-IR-SC is used to enable high-speed, reliable, and scalable connectivity in large-scale network environments.
