Description:
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
Providing one STM-1 interface (optical/ electrical) and one FE interface(optical/ electrical)and Gigabit Ethernet interface(optical/ electrical),hot swap for all daughter boards, convenient for maintenance and replacement.
CL-EOS carries potted Ethernet services via VC-4 in SDH;
CL-EOS provides very low time delay and delay jitter(within 10μs), supporting real-time data transmission QOS;
Modular design, compact conformation (19 inch 1U ),desktop or rack mounted;
Optional configuration for power supply:AC220V、DC-48V , single power supply、AC220V &DC-48V and redundancy power supply or
Supporting remote fault alarm and power monitoring, hot swap for power module;
NMS type device, supporting SNMP based on Ethernet interface, supporting third party MIB browser management, supporting Ethernet graphical management software,
supporting RS232 hyper terminal management(TL1 command line);
Independent installation and start for NMS software and hardware, NMS fault and line up NMS with business will not affect the normal business,
