Information
The Cisco 4OC3/ATM-IR-SC is a network module or interface card designed for Cisco routers. It is specifically designed to provide OC-3 (Optical Carrier level 3) connectivity using ATM (Asynchronous Transfer Mode) technology. The "IR" in the name stands for "Intermediate Reach," indicating that it is designed for medium-range optical connections. The "SC" refers to the type of optical connector used, which is the Subscriber Connector. This module allows routers to connect to ATM networks at OC-3 speeds, which is equivalent to 155.52 Mbps (megabits per second).
