Framed E1 Interface Conve er is an Ethernet bridge of high performance, which accomplishes the conve ing between the 100M Ethernet po and the E1 po . As an extended device of the Ethernet, the FE1 to Ethernet Bridge realizes interconnection of two Ethernet by using the E1 channel provided by existing networks with low cost.
100BASE-TX (RJ45) interfaces are provided at the end of Ethernet LAN to accomplish various functions including MAC address self-learning, address filtering, address table maintenance and flow control.
E1 interfaces conforming to ITU-T G.703 and G.704 proposals are provided at the end of WAN, suppo ing RJ45 and BNC connection modes. The E1 po s suppo both framing and un-framing architecture. The user can select an operating mode for the E1 interface according to the connected E1 environment. This provides flexibility of network application. In the framing mode, the E1 interface provides a rate of N*64Kbps（N=1~31）. In the un-framing mode, the E1 channel provides a rate of 2.048Mbps and accomplishes transparent transmission.
The FE1 to Ethernet Bridge provides plenty of self-test functions, suppo ing local loop and remote loop. It also provides pseudo random code test function to test error codes in the circuit.
Features:
- Realizes monitoring of remote equipment from local equipment;
- Upper LED row indicate local status, lower row indicate remote status, easy to understand easy to use
- Based on self -copyright IC.
- Ethernet interface Semi/full duplex self adapt, suppo VLAN
- Ethernet interface suppo auto-mdix.
- Provide 2 clock types: E1 master clock, E1 line clock.
- Provide 3 loop functions: local loop, to remote loop, order remote loop.
- Have pseudo random code test function, easy the installation and maintenance.
- E1 can suppo rate N*64k (N=1 to 32)
- Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance.
- Have Ethernet monitor self-reset function, equipment will not dead.
- Provide detecting realtime Ethernet communication status.
