Cisco NM-1FE1CT1-CSU

The Cisco NM-1FE1CT1-CSU is a network module designed for Cisco routers. It provides one Fast Ethernet (FE) port and one Channelized T1 (CT1) port with an integrated CSU/DSU (Channel Service Unit/Data Service Unit). The Fast Ethernet port supports data transfer rates of up to 100 Mbps, allowing for high-speed connectivity to Ethernet-based devices. The Channelized T1 port supports T1/E1 connections, which are commonly used for voice and data services in telecommunications networks. The integrated CSU/DSU provides the necessary functions for connecting to T1 lines, including line coding, framing, and clocking. This eliminates the need for an external CSU/DSU device, simplifying the setup and reducing equipment costs. Overall, the Cisco NM-1FE1CT1-CSU is a versatile network module that combines Fast Ethernet and T1 connectivity with an integrated CSU/DSU, making it suitable for various networking applications.
