Protocol Converters

详情

Product overview:
E1/Ethernet protocol converter provides the transmition between ITU-G.**3(E1) interface and *0/**0Base-T interface. High capability,self-adaptable long-distance Ethernet net bridge.the device start the standby chain while E1 line connectionless. Learn LAN MAC address uninterruptedly, transmit the MAC address as frame. Make TCP/IP transparent, provide communication safe, seamless connection.

Features:
1. Based on self-copyright IC;
2. Ethernet interface support jumbo frames (***6bit);
3. Have the function of E1 interface loop return examination, avoid the converter  crashed because of interface loop return
4. Examines if the malfunction because of the device crashed or E1 line is broken while lose signal or frame; 
5. Can set the E1 line not to send the LINK signal to Ethernet interface while it is error;
6. Ethernet interface *0M/**0M, half/full duplex self adaptable, supporting VLAN;
7. Ethernet supports AUTO-MDIX（crossed line and straightly connected line self-adaptable ）;
8. Realizes set the Ethernet port in 5 random mode, realize AUTO-MDIX function on-off;
9. Provides 2 clock types: E1 mast clock, E1 line clock;
*0. Provides 3 kinds of loop-return function: namely E1self-looping at local end (ANA), Ethernet *1. Self-looping at local end (DIG), and Ethernet being ordered to self-loop at remote end (REM);
*2. Has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;
*3. Supports *5&branded;/unbalanced and **0&branded;/balanced impedance at the same time;
*4. Network management interface uses SNMP;
*5. Can compose Ethernet net bridge (A)—E1 Modem (B)—Ethernet fiber Modern (C) topology structure;
*6. Can compose Ethernet net bridge (A)—Ethernet transmission device(B)—Media converter (C) topology structure.
