*4E1 to 4Ethernet converter
*BNC and RJ45 offered
*GFP VCAT LCAS
*AC and DC power
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.
* 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.
