Device Overview
CL-EOS Series take SDH technology as its core to provide access, provide broadband IP service, realize access and convergence faced with broadband data application, and is a device for comprehensive access conversion in the applications between Ethernet access services and SDH load-carrying net.
The devices is supplied with 2 interfaces, STM-1 interface (network interface) and 100M Ethernet and 1000M Gigabit Ethernet interface (user interface), Ethernet data frames from access network received by Ethernet interface is converted STM-1 SDH frames, and conveyed to SDH rig net through STM-1 interface. Whole communication is realized through convergence and data receiving on the opposite terminal.
Providing sound level ensured data transmission service, module designed for complete device, STM-1 interface and Ethernet interface can be optional for electrical or optical port.
Typical applications include IP DSLAM backhauling, enterprise connectivity, and high-bandwidth private line services¡£  Device Feature
