E1/4ETH Physical isolation converter

E1 / 4ETH physical isolation protocol converter provides four 10 / 100Base-T Ethernet interface multiplexed to ITU-T G.703 standard E1 interface capabilities to provide users with maximum speed of not more than 1984K Ethernet access. Widely used in finance, securities, security departments need to provide two different networks, and the two networks can be completely isolated physically. As the financial system business network, internal office network can not be associated with its business network, local interface multiplexer can solve this problem.

The protocol converter is a high performance, adaptive remote Ethernet bridge. Its small size, low cost, it is suitable for cost-sensitive bridging applications or as a LAN extender or segmented basis of bitstream structure. Widely used in between WAN and LAN networking, monitoring and other occasions.

□ based on proprietary integrated circuit;
□ built dynamic Ethernet MAC address list (4096), with local data frame filtering function;
□ 4-way Ethernet total rate of 1984K, set up the first after a 3-way rate, the first four Ethernet speed automatic allocation;
□ E1 interfaces and two Ethernet interface has lightning protection;
□ there can detect E1 loopback, and is indicated by the indicator;
□ can distinguish E1 signal loss when the remote device is powered down or disconnected intermediate transmission E1;
□ Ethernet interface 10M / 100M, full / half duplex fully adaptive, support VLAN protocol;
□ Ethernet port supports AUTO-MDIX (crossover cable and straight-line adaptive);
□ provide two kinds of clock ways: E1 master clock, E1 line from the clock;
□ can force the device to follow the rate of the end of the end of this end;
□ provides three loopback function: E1 local loopback (ANA), Ethernet local loopback (DIG), command the remote Ethernet loopback (REM);
□ while supporting adaptive 120Ω / balance and 75Ω / Imbalance impedance, no need to make settings;
□ support desktop, 1U high 19-inch rack-mount, 4U chassis card type;
□ support SNMP network management;
