EOP 4E1/ETHERNET Protocol Converter
Humanity HM-C200B 4E1 to Ethernet converter realizes Ethernet transmission over 1~4E1. This model complies with ITU-T G.7041, G.7042, G.7043, G.8040 and able to work with third party device followed same protocol.
Main Feature:
- Realize Ethernet data transmission over 1~4E1
- 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 (BER more than 1E-6 or a serious warning LOS/AIS/LOF or the signal loop back); Auto-restore the use of E1 after eliminate the failure.
- The E1 spur track on both ends can be connected not according to the serial number. If one E1 channel fails, the rest channels can still work.
- For 4E1 channels, the maximum tolerable time delay difference between any two can be up to 220ms.
