● Based on self-copyright IC;
● Support unframed mode (2048K) set and can manage the remote device condition, OAM management data did not take up the user’s timeslot;
● Have the function of the E1 interface loopback check, to avoid the converter crashing because of interface loopback;
● Have indicator when the device is power-off or E1 line is broken or lose signal;
● Can set the E1 line not to send the LINK signal to the Ethernet interface while the E1 line is broken;
● The Ethernet interface supports jumbo frames (2036 Bytes);
● Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering;
● Ethernet interface supports 10/100M, half/full duplex auto- Negotiation, and AUTO-MDIX (crossed line and straightly connected line self-adaptable );
● Have the Ethernet monitor self-reset function, the equipment will not dead;
● Can achieve the remote device setting any 5 modes of Ethernet and can close the AUTO-MDIX function;
● Provide 2 clock types: E1 master clock and E1 line clock;
● The local device can force the remote device rate to follow it (when the device is unframed mode, that is invalid);
● Have three Loop Back Mode: E1 interface Loop Back (ANA), Ethernet interface Loop Back(DIG), Command the remote, Ethernet interface Loop Back (REM);
● Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
● Support SNMP Network Management;
● Can realize monitor of remote equipment temperature and voltage from local equipment;
● Can form the structure: Ethernet E1 Bridge(A)---E1 Optical Fiber Modem(B)---Ethernet Optical Fiber Modem (C);
● Can form the structure: Ethernet E1 Bridge(A)---Optical Ethernet Modem(B)---Ethernet Optical Fiber Transceiver (C), can manage (B) and (C) at (A).
