Ethernet over TDM CCOM Communication

10/100Base-T Ethernet to E1 Converter
NIC-EBS/L/i

Is a type of high quality and self-studied Ethernet bridge, realizes the conversion from 10/100Base-T Ethernet interface to G.703 E1 interface. As the extended equipment of Ethernet, it could be used to connect two Ethernets transparently and adapts to found remote network connection at low cost.

NIC-EBS/L/i has a build-in Ethernet switch module inside, which could save one Ethernet Switch or users, the Ethernet VLAN mode provides four Ethernet separate channels which is based on the physical layer.

NIC-EBS/L/i catches the MAC address of the LAN which connected with it automatically. It only transfers different LAN segment traffic to destination, which can prevent the broadcast storm and provides flow control function.
