Detailed Description
Description: 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 connection-less. 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 (2036bit);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 10M/100M, 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;10. 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);12. Has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument;13. Supports 75Ω/unbalanced and 120Ω/balanced impedance at the same time;14. Network management interface uses SNMP;15. Can compose Ethernet net bridge (A)—E1 Modem (B)—Ethernet fiber Modern (C) topology structure;16. Can compose Ethernet net bridge (A)—Ethernet transmission device(B)—Media converter (C) topology structure.     Technical parameters: E1 Interface Interface Standard: comply with protocol G.703;Interface Rate: n*64Kbps±50ppm;Interface Code: HDB3; E1 Impedance: 75Ω (unbalance), 120Ω (balance); Jitter tolerance: In accord with protocol G.742 and G.823 Allowed Attenuation: 0~6dBm Ethernet interface (10/100M) Interface rate: 10/100 M bps, half/full duplex auto-negotiation Interface Standard: Compatible with IEEE 802.3, IEEE 802.1Q (VLAN) MAC Address Capability: 4096 Connector: RJ45, support Auto-MDIX Power Power supply: AC180V ~ 260V;DC –48V;DC +24V Power consumption: ≤3W Dimension Mini Type: 216(width)X140(depth)X31(height)mm 19 inch 1U:  483(width)X138(depth)X44(height)mm Working environment Working temperature: -10°C ~ 50°CWorking Humidity: 5%~95 % (no condensation) Storage temperature: -40°C ~ 80°CStorage Humidity: 5%~95 % (no condensation)
