E1/4ETH Logical isolation converter

E1 / 4ETH protocol converter provides ITU-T G.703 standard E1 interfaces and four 10 / 100Base-T Ethernet Interface Converter, 10 / 100Base-T channels will be transferred to the switch, HUB, routers, bridges or other devices on, and through the use of existing networks (PDH / SDH / microwave, etc.) provided by the E1 channel transmission, after two LAN networking has become both a LAN segment.

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 10M / 100M Ethernet interface isolated from each other, achieve Independent Communications
□ E1 interfaces and four 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;
