Humanity HM-C200B 4E1 to Ethernet converter realizes Ethernet transmission over 1~4E1.

This model complies with GFP, VCAT, LCAS and able to work with third party device followed same protocol.

• Realizes Ethernet transmission over E1
• Comply with ITU-T G.7041, G.7042, G.7043, G.8040. It’s able to work with third party device followed same standard ITU protocol. 
• Support auto delete the fault E1 channels. Auto in use after E1 is normal.
• E1 can not connect according to serial number. In case one E1 failure, the other E1 can still work.
• For 4E1 channels, the maximum tolerable time delay difference between any two can be up to 220ms.
• Chassis type supported
• MBTF: 50000hours
