AN-4E1-4ETH Interface Converter is a device that takes ASIC chip as its core and enables Ethernet data to be transmitted through multi 4E1 channels. AN-4E1-4ETH Interface Converter breaks through the bandwidth limit of single E1 Ethernet bridge. It is very easy to make use of the existing rich E1 resources in the public networks to quickly extend the range of the Ethernet LAN. AN-4E1-4ETH Interface Converter is an enhancement model of the Ethernet to multi E1 converter. It means that with a built-in bit error detector, the device can find which E1 is not capable to be used because of too much bit errors, and then automatically cut down the bad one, to keep the Ethernet data transmission continuously.
AN-4E1-4ETH Interface Converter is a multifunction and high performance L2 switch which build in the port cross engine to realize the conversion between two Ethernet interface and E1 interface. The equipment supports the function used as Ethernet transceiver or Ethernet net bridge. As the extension of Ethernet, This converter may realize Ethernet interconnection at low cost via the E1 channel provided by existing network.
E1 interfaces conforming to ITU-T G.703 and G.704 proposals are provided at the end of WAN, supporting RJ45 and BNC connection modes. The E1 ports support both framing and un-framing architecture. Each channel can support 31 time slots for transmit. The 4 E1 channel provides a rate of 7.936 Mbps and accomplishes transparent transmission.
The equipment uses 10/100BASE-T Ethernet interfaces and supports adaptive 10/100M half/full duplex mode. Ethernet devices connected to AN-4E1-4ETH bridge (such as SWITCH, HUB, Ethernet adapter card (NIC), etc.) can be set to 10M full duplex, 10M half duplex, adaptive 10M half/full duplex and adaptive 10/100M.
Users can directly query and set the status of a pair of devices with the 4E1 management software Via RS232 wire (available 3 line,2—2,3—3,5--5). The software will automatic test the device’s type model and the currently state of Ethernet, the alarm of every channel E1’s LOS, LOF, AIS. For the normal E1 channel, we can check the state of remote Ethernet connecting, etc.
