E1-10/100BaseT Protocol Convertor

FTTH-CHINA new style E1-10/100BaseT protocol converter. The device provides the transition between ITU-T G.703 (E1) standard E1interface and 10/100Base-T interface. It is a high capability, self-adaptable long-distance Ethernet net bridge. The Ethernet interface support jumbo frames (2036bit); have the function of E1 interface loop return examination, avoid the converter  crashed because of interface loop return; 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.

Characteristic:

• Based on self-copyright IC;
• Ethernet interface support jumbo frames (2036bit);
• Have the function of E1 interface loop return examination, avoid the converter  crashed because of interface loop return
• Examines if the malfunction because of the device crashed or E1 line is broken while lose signal or frame;
• Can set the E1 line not to send the LINK signal to Ethernet interface while it is error;
• Ethernet interface 10M/100M, half/full duplex self adaptable, supporting VLAN;
• Ethernet supports AUTO-MDIX（crossed line and straightly connected line self-adaptable ）;
• Realizes set the Ethernet port in 5 random mode, realize AUTO-MDIX function on-off;
• Provides 2 clock types: E1 mast clock, E1 line clock;
• Provides 3 kinds of loop-return function: namely E1self-looping at local end (ANA), Ethernet 11. Self-looping at local end (DIG), and Ethernet being ordered to self-loop at remote end (REM);
• Has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;
• Supports 75Ω/unbalanced and 120Ω/balanced impedance at the same time;
• Network management interface uses SNMP;
• Can compose Ethernet net bridge (A)—E1 Modem (B)—Ethernet fiber Modern (C) topology structure;
• Can compose Ethernet net bridge (A)—Ethernet transmission device (B)—Media converter (C) topology structure.
